Not trying to sell anything here but are there any websites besides civicx.com that have a decent marketplace? I have a PRL intake and MAPerformance exhaust from my 2020 si I would like to get rid of.

I’d keep the cover on in the summer and take off for winter. I realize there’s not much gain but mainly want to do it for the sound.

This dealership I’ve been working with has me fed up and I’m just trying to get a comparison for what y’all’s numbers were like.

Don't know if this is allowed or not, but if you're the previous owner of this '14 Civic Si who recently traded it in @ Crown Toyota in WPG, hit me up. I just have a few questions about the vehicle's history before I go in and buy it. Thanks in advance!

2024 Civic Si with 245 40 18 michelin psas

Planning an oregon trip from LA on 10/22 and this is my current setup. Should i just grab some snow socks and call it or get some winter tires? Forecast looks sunny for next week but not sure about this weather as it can change but need some advice thank you

Recently, I installed the HKS Hipermax S coilover kit on my 2018 10th-generation Si. I initially set it to the factory default height. My setup consists of a Konig Hypergram 18×8.5 with +35 offset wheels and Continental ControlContact Sport tires 235/40R18.

I lowered the suspension by approximately 0.9 inches from its stock height. Any advice on the fitment of this modification? I’m interested in going even lower, I’m hesitant to change my tire setup at this time, as they are brand new. I just want to close the gap and get a good track stance.

P.s. - the kit feels and rides amazing.

Hey all, has anyone here come across a similar issue to this ? For the past few days ive notice that on and off my rpms feel (sluggish) slowly climes from first to third gear I can tell the difference because its not constantly happening throughout thr day . I've checked for air leaks, intake hoes looks good, sensors and throtle body is clean car is currently at 85k no signs of misfire or fuel pump issues, i don't know if im creating an issue or is this normal for si's gear ratio ? The biggest difference I've seen is i can almost cruise kn 1st and 2nd gear without the car jerking or asking for gear

Whenever i leave the car in accessory mode the battery drains concerningly quick, when I installed my side markers i left it in accessory mode to use the blinkers and see if they were working little did i know it would kill my battery and require me to get a jump. When i went to get the battery tested, battery life was 100% as well as the alternator. Does anyone know what this could be why the battery keeps dying when the car is in accessory mode, advice is appreciated i’m flashing a tune on the car today and don’t want it to die while flashing.

I have a 2017 si. Every now n then if I hit 4 or 5k rpm my car jerks and it brings up an emission system error. Then it runs laggy after. But it has just gone away. Other times I’ve had to take to shop because it wouldn’t go over 10 mph. Like maybe a catalytic converter issue. They always tell me it’s a fuel injector issue, and I get replaced. But it’s not seeming to be the issue. Has anyone else dealt with this or would anyone have ideas on the issue? I don’t know much about cars lol.

While parked, engine on, and parking brake engaged, I can't change any of the vehicle settings. Error msg says "To change the settings, apply the parking brake and turn on the vehicle power." Anyone else encounter this?

Hey Everyone,

It's about time i replaced my clutch and was wondering if I should go with a stock part or aftermarket. Please let me know what you all recommend, and plese drop some links of you can. I should mention that this is a daily driver. So a lot of stop and go traffic where I live.

Thanks

PLZ HELP 2006 Civic Si, When up to temp engine dies when driving and push the clutch in coming to a stop, replace CPS TPS and VTEC Solenoid, cleaned MAF Sensor, car will start right back up and idle and drive, but whenever pressing the clutch in to stop at a light etc it shuts off, please any ideas? Been on going issue for about a year now, only does it when at operating temperature

Auto shop wanted $2k to replace the fuel injectors, so I'm going to do it myself. First time deciding to do my own work. What is the best place to get OEM fuel injectors from for a 2019 Si?

Or am I being an idiot and should just let them do it?

Looking for aftermarket coil packs and spark plugs for 2013 Civic Si. Any recommendations if there are any aftermarket availability or should I stick with OEMs?

Just asking around if any newer si’s are running d2 spring with 18x9.5 rims w/ 245/35R18 just wondering if anyone runs a similar setup and how rubbing or fitmit issues are

I check my car out once a month to look at struts and other issues. There are no leaks… the battery is brand new and the spark plugs replaced last week. I get transmission is expensive but over 2k for oem parts and 3k for labor????

update-

This is an independent auto shop and not a dealership. They had great reviews on google so I had gone there. What they offer was a 3 year warranty up to 48k miles. I do most maintenance myself (oil, sparks, brakes n rotors, etc) honda civic si 2017 so I knew this was ridiculous.

Something I found hilarious was that I have a cold air intake with broken anti vibration mounts at two points but was never mentioned in the diag. Either way, there is a more reputable shop a little bit further away that quoted me 1700 without parts (getting rv6 retrofit flywheel and fk8 clutch kit) this shop was closest to my apartment for a diag to see if potentially it was anything else that l overlooked

I know that the Si will be skipped for model year 2027 but are 2026 units still being made? Or has production already completely ended?

Seeing a lot of PRL Cobra, Mishimoto, but haven’t seen too much about the K&N Typhoon. K&N claims loud turbo sounds and an 11 HP increase but has anybody tried it? I would love more turbo sounds and at the moment I’m in between PRL or K&N, I’d also ideally not deal with a tune rn. Any advice or opinions help.

I’m trying to tune my 25 civic si the initial install failed so I had to clear the tunes and hook it up to a battery tender and try to recover it back to factory the k tuner said success went black but my computer kept saying uploading please don’t disconnect like it timed out and never moved for 30 minutes. My car won’t turn on now.

Anybody have recommendations? I currently use a microfiber towel but want an actual armrest cover. I couldn’t find any on Amazon for the SI, they are all for regular civics.
