Hi All, I am posting an issue that can be caused from washing your air filter and not allowing it to dry fully/a PSA on how long it actually takes to dry (I have the 27 Won intake). Over the weekend I changed my oil and cleaned my air filter for the first time. I followed the instructions...

Can a moderator do something about all the spam posts in an Asian language?

Hi All, Can you listen to this clip and tell me if you hear a slight mis-fire at idle? My car has never idled super smooth, even when brand new but I’m wondering if some valves are overly tight and that could be the cause. It’s never thrown any codes.

Hi All, For the past few weeks, I’ve been have this symptom: I restart my car after getting gas and there is an uneven idle, it feels like a misfire, but there is no check engine light. The rpms don’t really fluctuate, but I feel it in the seat and hear it. Once I’ve driven for a bit it...

Does anyone know if wastegate arm rattle is a potential performance issue or failure point waiting to happen? My wastegate arm rattles occasionally, and I can't tell if it creates a performance reduction or not. Those who are upgrading their turbos, are your electronic wastegate and recirc...

Anyone else have a tire shop install TPMS sensors on their civic unnecessarily? I'm just annoyed that shops can't use simple research skills and for being charged extra for something I didn't need. Only noticed after the fact and seeing after I adjusted the tire pressure down from over 40psi...

Hi All, Can anyone help me identify this noise? I’ve been hearing it on and off for around a month now. Usually only on light to moderate throttle just as the turbo starts to build a little boost. Sorry for the wonky video, but finally captured the sound of it. Sounds like a distinct rattle...

Hi All, I’m thinking of changing to 245-45-R17 tire size on my 17x8 rims the next tire change. Currently on 235/45s which are slightly smaller diameter than stock (-0.4%) whereas the new size would be an increase of 1.2% over stock. So my speedometer would read slightly low and effectively...

On New Year's Eve last year, my stock clutch failed catastrophically. I had made another post about it when it happened, suspecting a hydraulic issue due to the clutch pedal getting stuck when it happened (this was not the case as you will see). I had not really experienced any slippage, or at...

Just had a pretty scary and potentially life threatening situation. Pulled out into traffic and could not get into 2nd or any gear. Clutch pedal stuck to the floor. Pulled it back up manually with my foot. Clutch not engaging correctly, and horrible grinding noise, when trying to engage...

Hi All, Yesterday I went to start the engine cold, the starter activated normally, but before idling normal, it was like like only one cylinder was firing and the engine did a slow surge between 0-500 rpm for a couple seconds before firing normal. Should I be concerned about injectors? Spark...

Looks like the 11th gen 1.5t will be getting VTEC on exhaust valves? Wonder how that will impact performance tuning on Si. “Powering EX-L and Sport Touring trims is a turbocharged 1.5-liter 4-cylinder producing 180 horsepower at 6,000 rpm (SAE net) and 177 lb.-ft. of torque at 1,700 to 4,500...

Hi All, As I am approaching 75k miles, my shifter has started feeling weird, like there is some sort of plasticy resistence right before going into gear. I have had the acuity shifter cable bushings in since new, and the last 74k + miles have been very happy with the feeling of the shifter...

Hi All, I replaced my transmission fluid with Amsoil for it’s second change. The first change at 30k was done with Honda fluid. The stock fluid does need to be changed out every 30k. You can tell certain gears seem to be less smooth and more notchy. That being said, I felt my transmission...

Earlier today while driving to a job, it was greasy out, a bit of drizzle and some light rain. While there is still some tread left, the stock GoodYears are becoming dangerous in the wet. Any attempt at getting on the gas leads to spinning and wheel hop. Several times I could feel the car...

Hello, So at some point in the next few months I am going to get new tires. I am still on the factory all seasons in the summer. Wet traction is really becoming an issue to the point of being dangerous. I already have a winter set of wheels which are 17x7.5 that I use from December through...

Hi All, I am debating intercooler purchase between 27won and Garrett. Is anyone running the Garrett unit? I’d save over $200 by going Garrett. It doesn’t come with piping so uses the stock piping, but is that actually limiting anything? Garrett claims their unit supports up to 660hp. 27won...

Hi All, I’m looking for some feedback here about coolant temps from those of you that monitor your data while driving. It’s been in the 90’s here, and since I live up a mountain, I have about 1200 feet elevation change of continuous climbing for several miles to get home. Monitoring coolant...

Hello, I am just posting this out of curiosity as I recently discovered that Shell premium in Canada has 0% ethanol. Here in US everything has 10% ethanol. Just wondering if anyone has experience with that.

Greetings, I just wanted to share my experience installing these parts. First, the subframe brace: I don’t know about anyone else who has installed this, but I had a considerable problem with one of the threaded holes for the subframe brace. Before I even did anything, I sprayed the holes...
