This is a common choice.

Seems to be one of the first mods a lot of owners do.

u/DexRogue · 8 pointsr/Charger

Buy a catch can ASAP. If you're 100% set on buying the SP, order a Billet Technology one now (if you want that brand, fantastic quality) as the delivery time is insane. I ordered mine the day before I took delivery of my SP and it took over ten weeks to get it.

Buy a replacement air filter, I'd suggest the K&N (only because I have it, there are plenty of dry ones you can get as well) just a piece of mind thing. It has a rebate right now so you can pick it up for $34 which is awesome.

I would also suggest to swap out the brake pads if you know how. The stock brembos are great but they are noisy (they squeal before they are heated up) and create a TON of dust. I'd suggest PowerStop Z23/Z26. I personally went with the Z23s, seems silly as your pads will be new but you'll thank me later. The lack of dust is incredible and they stay super touchy.

Are you planning to order your SP? I'd highly suggest the Plus Group and I'd even consider the adaptive suspension. (though I've never used it or experienced it I think it would be neat) The dynamics package isn't really that important unless you're planning to track the car (the 4 piston brembos stop the car on a dime) and you can stick a 275 on the stock rims.

Cheap, easy, and butt dyno approved:

You could use a line dryer.

u/tolas · 7 pointsr/Golf_R

I think DSG paddle replacement is worth it, especially the real ones (not the stick ons). Those racing lines look nice. I love my S2T Performance ones.

Drop in air filter and removal of the snow grate. SLIGHTLY more intake/turbo noises and for $60 you're getting roughly the same air flow "performance" as $300-$600 aftermarket intakes.

Tires. PS4S for Summer, RE71r for track/autocross, Alpin PA4 for winter.

Wheels 18" Konig Flow Form Wheels (i have the Rennform) are around 18lbs, which save a good bit of unsprung mass. I rock my Pretorias in the summer, and switch to my Konig's with the RE71r's for autocross/track.

I also just got the ECS subframe mount insert but haven't installed it yet.

u/XR999 · 6 pointsr/Justrolledintotheshop

An ASSTOY640 oil filter wrench. They are used to remove the caps of cartridge filter housings (an example with the tool to remove it installed on it) which manufacturers from many makes have started using in place of standard spin-on oil filters.

Instead these housings are a reusable plastic or metal container that house a replaceable filter element (this one is an example of a Prius filter) and depending on the vehicle manufacturer some require special tools to remove the cap correctly without damage.

Others though use a nut on top that you can buy a special socket set for although depending on the access available, you can sometimes use a regular 1/2 drive socket instead (Dodge Grand Caravans for example as they take a 24mm socket to remove).

The main reason why this tool failed though is because many Toyota models are known for breaking these tools when people overtighten the housings on reinstall and then when the next guy goes to remove the housing, it's simply on too tight for the tool to be able to withstand the force required to remove it. Heck I've seen one on so tight that an air hammer was required to finally remove it, followed by the last guy who installed it getting an earful about it.

So it is actually a 3 part ordeal.

The actual fog lights since my car didn't come with them, and the stalk. Then I did some c-shaped drl since I have leds in my high beams and the factory drl doesn't work with leds, but then the c-shaped drl didn't work for a little bit so I bought the drl turn signals, and then the previous c-shaped ones started working again. I will just post all of my mods below:

I had my rims done by a local company, they are the factory 16" painted gloss black. My mazda emblem is actually a long story, but essentially it is just scuffed up with sand paper ready to be painted but I liked the look and stuck it back on the way it is. I have also installed car play, and 3D printed a shift knob. The factory bose system was a little lacking and put a small under seat sub in to help fill the sound, but am still not happy with it, so that's a future project.

Some near future plans for the car include the aero kit, and I'll post the links to those here too:

Seriously took 10 minutes to install!

The sound is...visceral, a growl and rumble, you can hear the engine suck in air with a whistle even.

u/zxbc · 3 pointsr/mazda3

Air filter upgrade is the cheapest and easiest to install. A tiny bit boost to horsepower and gas mileage.

u/thisonewillsurelybef · 3 pointsr/cars

The best you can do is improve ride and handling. Lighter, sportier wheels. A coilover spring kit. Removing unnecessary weight from the trunk or cabin. Install a lightweight battery.

You could consider adding a high flow filter to get some more induction noise which can make the drive more exciting. https://www.amazon.com/Corolla-Matrix-Reusable-Washable-Replacement/dp/B074XLNDC4

Your engine is not tuneable, modern toyotas ECU are locked down.

u/DigitalBaka · 3 pointsr/FocusST

Open ended oiled filter. Seen them in the $40 range on Amazon occasionally. Not much performance gain but the noise is good for miles of smiles.

Was approx 70 degrees today, i would expect it to be even higher in the summer.

Installing Racing beat axleback and a full set of Michelin CrossClimate + this weekend :)

u/coozyorcosie · 3 pointsr/FordFocus

I went with this AEM filter because it's closed. Seems to work well + has the advantage that it's a dry filter so it's easier to clean.

The snorkel delete shouldn't really change the temp of the air coming into the intake, you're just taking off a piece that restricts the flow.

u/survivedtheclap · 2 pointsr/infiniti

Grille looks good with the Takeda, man. I'm running this filter instead of a shield. Ended up fitting perfectly https://www.amazon.com/gp/product/B01NCJI7V2/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

u/frsh2fourty · 2 pointsr/Cartalk

I can't give advice for the insurance portion other than just continuing to pester them about the supplement since it sounds like they are giving you the run around till you give up but I'm guessing the dealer can't get in touch with the adjuster just like you.

What likely happened is when the mold developed it got trapped in your vents and since the shop was only paid to clean the carpet, thats all they did. So what I would suggest is finding somewhere local that rents ozone machines and stick one in your car for a day or two. Here is one in Houston from a quick search. At my old job we had one for apartments that were flooded or smoked in and we used it in my friends car once after he had a pound of rotting meat under his seat for a week in the Texas summer (long story) and it got that smell out completely. Also, pick up one of these kits and use it, then replace your cabin air filter which should cost no more than $20 and is pretty easy to do. That should pretty much eliminate all the likely sources of the smell, at least enough to sell it. If the smell still lingers a little I would also put one of these in your car too and maybe stash it somewhere out of sight so if you do go to sell it, it won't be found during the inspection. Try their spray too, that stuff worked wonders and was always a life saver back in my high school pot smoking days.

u/abbyjo_0801 · 2 pointsr/shrooms

Never spray peroxide on the cakes and always let it sit for 24 hours before you add cakes to the environment it takes 48hours before it converts to just water.

I've never had any issue soaking with a little peroxide but the key is to let it sit for the 24 hours and don't wait longer or the peroxide is all gone and it was near pointless to add it.

It's almost the exact same one from Midwest I just find two tubs at Walmart the outer/bottom one is filled with enough water to cover the heater with 2 inches extra. The top/inner tub is where the cakes go. I have two setups one for incubation and one for fruiting. The only difference is the fruiting one has a hair hose and perlite base. This is the filter for the air, it let's you see if it's clogged or needs to be changed.

Hepa Sanitary Air Filter (In-line) (1) https://www.amazon.com/dp/B00QXRD3NA/ref=cm_sw_r_cp_apa_i_qn7OCbXZAZYPV

The fuzz is just mycelium growing at the base I never worry about that.

u/mkelleygcsi · 2 pointsr/FocusST

Got it here..

http://www.amazon.com/Green-Filter-7159-High-Performance/dp/B000CMHIR4/ref=sr_1_1?ie=UTF8&qid=1425668660&sr=8-1&keywords=focus+st+green+filter

Came pretty quick, got it in 2-3 days. As far as performance goes, there isnt much of a difference. It sounds great though! Left the top of the air box off.

Ive been thinking of getting the rokblokz myself. Window tint is iffy for me, due to it being illegal. Got popped in my RSX for it.

u/burritosmash · 2 pointsr/GolfGTI

2nd this...Got mine from Amazon and it's a decent change over the stock one. You can actually hear it "hiss" once you remove the "grate" in the airbox.

u/1_64493406685 · 2 pointsr/FiestaST

I think it all depends on what your goal for the vehicle is? Do you plan on tracking it? or just to make it a bit faster around town? Do you want it to look a little modified or stock?

Anyways, I'll link a bunch of stuff I personally prefer and in the order I would install them...

Accessories:

u/wyatte74 · 2 pointsr/mazda3

you can get them on amazon. I got this one for my 2017 so i think it should fit a 2016 too.

u/krazysrfr · 2 pointsr/FocusST

this one: https://www.amazon.com/gp/product/B000CMHIR4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

i like it so far it adds a bit more induction noise and it looks like it keeps the oil cooler just by a little bit.

u/that_software_dev · 2 pointsr/mazda3

AEM Dryflow (Gen 2 2.5L)
https://www.amazon.com/AEM-28-20293-Dryflow-Air-Filter/dp/B00B98TUDK/

K&N "High Performance" (Gen 2 2.5L)
https://www.amazon.com/33-2293-High-Performance-Replacement-Filter/dp/B000CO9T60/

Yeah yeah, they say high performance. That's just marketing. The biggest difference will be the savings on replacements if you're doing more than two or three changes before selling the car. Make sure to get the one that matches your engine, I linked the 2.5L Gen 2 filters since that's what I own.

u/irmikexp · 2 pointsr/XVcrosstrek

K&N drop in thats dry. Just take it out to clean once in a while

u/MisterNoisy · 2 pointsr/cars

Not really - I quite like the car 'as is'. The only thing I've done is add a weighted shift knob and some goofy decals.

EDIT: Also a Green Filter for more turbo noise in the cabin.

Green Filter 7159 Green High Performance Air Filter https://www.amazon.com/dp/B000CMHIR4/ref=cm_sw_r_cp_tai_IaEszbMN7H88X

Resonator is part of the exhaust system, $50 From my local muffler shop to remove it and put a straight thru . Gives the exhaust a little character without being loud

u/eras · 2 pointsr/Futurology

I believe you are completely correct. It seems it is the Model X that has a quite a bit larger HEPA filter, 40"x12"x1" according to https://www.amazon.com/dp/B0779WGQWQ/ .

u/schlipps · 2 pointsr/Homebrewing

Surely! I have 6-gal plastic carboys. I currently have a carboy cap that has a racking cane and a filter on the other end. The end of my racking cane tubing is attached directly to a barbed disconnect on the liquid post. I still use gravity but I get the siphon going by blowing through the filtered end of the carboy cap. I actually am purchasing this today to replace the filter so I can use pure CO2 to push the beer from my carboy. Just know if you use CO2 to push the beer from the carboy to keg that you need to keep the pressure very low as the carboys are nor pressure retaining vessels.

I have to give credit where credit is due though. I built this after seeing /u/brulosopher 's kegging method

u/Silenthunter87 · 2 pointsr/FocusST

purchased mine from Amazon because, free prime shipping.

u/M4STERB0T · 1 pointr/FiestaST
u/Jcconnell · 1 pointr/GrandCherokee

For completeness, here is what I'm testing now: https://imgur.com/a/WhLov

This cost about $25 from Autozone and included all the parts required to complete the setup you see above. It required no modification of the factory parts. Spectre 8131

It does not fit directly onto the throttle body but I think this may be a superior solution.

aFe dry filter. I'm running this in my car right now.

Here's a CTS intake hose that I am planning on getting. You may also benefit from a turbo inlet upgrade.

u/brrrrip · 1 pointr/MechanicAdvice

Yeah, sorry about it being a bit different. GM has a tendency to do things wildly different for no apparent reason sometimes.

I really couldn't find a decent picture or description anywhere.
Even this AutoZone image was just, 'here's all the parts': http://contentinfo.autozone.com/znetcs/job-info/en/US/07004001.jpg/1.image

There's no quick fix for removing solids from the ducting, but for smells try something like this: http://www.amazon.com/Clean-Air-Kit/dp/B000IMB4CI
That particular brand is supposed to work really well. I know we sold stuff like that at the parts store I worked at. Something like it should be fairly easy to come across.

I'm glad you got it taken care of. I'll be looking forward to the aftermath. I wish you a pile of karma.

u/munn3y · 1 pointr/veloster

For sure.

Here’s a link to the filter


You’ll need a 3in pipe and some clamps for it to go on. The pipe can be found for like $5 usually right by the spectre filters in autozone.



Edit: here’s a link to the step by step that I followed when doing mine

u/wordstrappedinmyhead · 1 pointr/CherokeeXJ

Yeah, it's the Spectre Performance 9948 Air Intake Kit for Jeep Cherokee 4.0L. I picked it up locally from Craigslist early on after I bought my XJ, was one of the first handful of mods I did. It uses the Spectre Performance HPR9833 Air Filter. Fits over the valve cover with no issues.

u/NicholasFarseer · 1 pointr/techsupportgore

I have a little pancake compressor in my shop I got specifically to dust off electronics. I use it occasionally for other jobs, but it's primarily a duster. I just use a short hose with a moisture trap installed inline.

I just couldn't stand buying canned air anymore.
