Top products from r/CivicSi

Costco carries the universal Weathertech product for $35ish. They are trim-to-fit type. I've never used them but they can't be terrible if Costco sells them, due to their return policy. Unless you're willing to shell out well over $100 (for back and front), something like this is probably your best option.

Edit: these are pricier but I got them recently and they fit great. https://www.amazon.com/dp/B06XDKVK9K/ref=cm_sw_r_other_apa_i_eVO4DbC9ZD1QA

First off, congratulations! The Si coupe is a brilliant car, both in terms of drivability and usability. It’s good to hear that the car already has some mods installed, but here’s a small little list I’ve made of other mods you could look into.

Performance Mods

• Hondata Flash Pro
  
• Acuity Throttle Spacer
  
• Eibach Front and Rear Sway Bar
  
• KSport Lowering Coilovers
  
• GReddy 304 SS Cat-back Dual Rear Exhaust
  
  

  Design Mods
  

• Mugen Shift Knob
  
• GarageLine 20mm Wheel Spacers
  
• Depo Type R Style Plug and Play LED Headlights
  
• Sporty Red Gearbox Trim CVT Only
  
  
  This is just a small list and I’m still building on it. Hope you can find some use for these mods!

I cannot speak for the honda Si, but i have the same issue for my honda ridgeline.

I ordered some lights from amazon. Basically you have to take the dash apart, get to the light, take the old bulb out and put in the new bulb. yes you can but the whole fixture for like 10$ a bulb - or just buy a pack of bulbs. You will reuse the "bulb condoms" for specific colors).

​

These are the bulbs i bought. They are not LED.

If you are going to do this., you could switch to LED, but do a little bit more research to figure out sizing. You could also change the colors if you want.. like decide instead of amber, you want red, or blue or something.

​

Edit to add : in my example of how to fix this.. you are reusing the base of the bulb - so removing th ebad bulb, peeling off the bulb condom (just changes the color of the bulb), then adding in your bulbs you bought, wrapping the wires in (take photos before you remove your old bulb of how the wires wind into the base).

Here is a post... about the ridgeline, but i bet it translates.

[I Bought these.](http://HD-Mart Car Rubber Floor Mat for Honda Civic 10th Generation 2016-2017-2018-2019 Custom Fit Black Auto Liner Mats All Weather, Heavy Duty & Odorless https://www.amazon.com/dp/B07N2L5M73/ref=cm_sw_r_other_apa_i_TGR4DbF6GDJA4)

They fit perfectly, and have held up well. Lacking in the looks department, though.

Honestly just Amazon. https://www.amazon.com/GZYF-Splitter-Spoiler-2016-2018-Plastic/dp/B07KJYBV44/ref=mp_s_a_1_4?keywords=Civic+si+splitter&qid=1573327758&sr=8-4
It's not super high quality, plastic similar to the bumper. But I used my own bolts and fasteners to attach and it looks super clean to me.

I bought a pair of bulbs from ledguys(.)com, but amazon has the same ones but cheaper. I looked for some like mine.

If you're desperate for dome punchier bass, there are always options. I doubt you want an aftermarket stereo so that limits your options. But you also have the option of getting something like this:

https://www.amazon.com/dp/B00I4EF1BC/ref=cm_sw_r_cp_apa_kzj.zbD5498FQ

With this you can splice from your speaker wire (or daisy chain from your rear speakers or subs) and turn them into rca ports for your amp. So you can add a subwoofer no problem. It might be a little more limited but it totally works. Unfortunately it doesn't take any stress from the other speakers but the '17 si speakers aren't too terrible anyway. They'd just sound better with a dedicated amp and some bigger subs. I hope this helps.

We were in the exact same situation and found that the Husky liners on Amazon worked great. I'll add a link in a sec.

Its really good vinyl i got from amazon VViViD Black Carbon Fiber... https://www.amazon.com/dp/B07DM32D9D?ref=ppx_pop_mob_ap_share

Looks like an adhesive mounted one. Sort of like this one. Never used that type though.

I have a CD Slot holder, since it happened to be exactly where I wanted my phone in my FB6 and, well, who uses CDs these days?

there's no getting around that its a complete PITA. yes, passenger front wheel off, car in the air (if you don't have a lo-pro jack, drive the car up on some 2x4's to give yourself an extra boost). do yourself a favor and get this thing called a "Form-A-Funnel", its a super malleable plastic sheet you can form into a gutter to carry the oil out from under the filter and over your control arm to drain into a bucket or rag or whatever. its not a hard procedure, just requires patience to deal with the filter.

You can buy LED bulbs for your fog lights that you can switch from white to yellow. You just turn them off and back on to switch from white to yellow. They are much brighter than the factory bulbs too.

So I believe this is what I'm dealing with..

Is this what I should be getting for this? Otherwise I can take it to a local specialty shop and ask them. Looks like the filter is right infront of the driver side wheel. Not sure If i should get someone to take off the front bumper or just the wheel wall to change it out.

The current filter looks really dirty...

Keep in mind I have the 18 SI so I’m not sure about differences between the 19/20.
