    Alabama FOR SALE: 286 hp, 339 lb-ft tq Civic Si Coupe

    Hey everyone. Owning/modifying my Civic Si has been an awesome experience. This community has been extremely helpful and friendly to me during my time here. Due to the needs of my family, I have decided to sell my 2019 Si Coupe. I will be switching to a 2022 Honda Ridgeline Sport. I will miss...

  5. Easiest way to plr filter?

    How often do you change the PRL CAI filter?

  6. Boost gauge not reading actual boost

    By “boost gauge,” do you mean on your Ktuner or the digital readout on your car’s factory gauge cluster? My car’s factory gauge cluster has never really showed the right amount of boost, but my ktuner data is spot on

    Alabama WTB OEM TYPE R EXHAUST

    I’m not, sorry! Thanks anyways though

  8. Grille popping out.

    Unfortunately, this is a very common issue. From what I’ve seen, the damage happens when people remove the bumper/grill from the car. The weak tabs that connect the grill to the car (I think they are on that small panel between the hood and the grill) are damaged. I replaced a chrome OEM grill...

    So sorry to hear about the crash. Does insurance cover any of the repair cost since it was on the track?

  12. 2020 Si speaker sub upgrade.

    Great thread! Thanks for taking the time to write this up for the rest of us. I'm looking to do this to my Si coupe. Do you drive a coupe or sedan? Is the stereo setup different between the two? I'm a total newb with sound systems. Is this something a complete beginner can do or will I be in...

  13. Knock knock. Who's there?

    OP, sorry to hear about your engine. gtman/hobby-man, I always thought that all the 1.5T non-Si’s used the L15BA and only the Si used the L15B7. Is this not the case?

  14. Si spoiler on non-si

    It can be done, and I think it looks good! I had it done by an auto body shop on my previous car (2016 EXT Sedan). There are some things to consider though. You will need to upgrade your trunk springs to support the added weight. Also, if you’re adding the Coupe spoiler, you’ll need to put...

  15. Euro/ JDM spec front crash bar?

    I wonder if modifying the crash bar setup like that would cause any legal issues in the event of a crash

    Alabama WTB OEM TYPE R EXHAUST

    Do you still have the muffler so I can get it welded back on? I’m looking for an exhaust that still has the resonators and muffler attached.

  18. Higher ECT Temp on 5w 30 oil

    27Won recommends using 5W30 if you have flex fuel, according to one of their YouTube videos. I use 5W30 in my Si without issues
