spark plugs

Hello guys, i have a problem in my 2018 Honda civic si coupé. its when i drive the car for like 4-5 hours, all light in dashboard will pop up and the check engine light start flashing so the car won't move, throttle not responding at all, RPM not more than 1.5k. I haven't modified the car...

Couple days ago I started getting this super weird noise when I would go to get on it. So I continued driving a couple minutes up the road and parked it. I took out the plugs and was checking them but cylinder 3 had coolant inside it. Well I tore the head off this weekend and head gasket was...

I'm going up to about 20k miles in my 21' Civic Hatch Sport, and am considering doing a spark plug replacement. Some people told me to wait till my car starts misfiring to switch out the spark plugs, but I'm not sure how reliable that is. I'm currently running phearable 1.5, light weight...

TRICKIEST MISFIRE EVER Car is already modded with PRL short ram intake (race MAF), and a TSP race MAF tune for 9 months with no issues. Been tuned for 1 year and 2 months, 28 000 km or about 17k miles. All started with a limp mode on Map 3 going 80% throttle. Car surged and CEL flashed, pulled...

Good Evening 10thgen Fam, I read the PRL Article about spark plugs for the 1.5L SI shop car they were using. I know they have a ton of performance mods (I think this may have been before the 150hp nitrous shot but honestly not sure). Long story short I'm looking to see if there's 2 step...

Hey guys, I have a 2020 civic si and I have been having some issues with it. I kind of have a rough idle and rough drive from idle to around 3000 rpm after that it gets smoother. Here are the mods I have: Catless fp/dp PRL race short ram intake tsp stage 1 on ktuner Rear motor mount Remark...

Hey guys, I just recently purchased a 2018 Civic Si with about 38,000 miles on it back in February and I’m at 44,000 now and I’m having some misfire issues. My car is barely modified unless you’d like to consider a K&N drop in filter and a muffler delete heavy modifications. I only use New York...

Hi Everyone, My car started showing the signs of engine hesitation and jerking out of the blue yesterday. Due to this Covid19 outbreak, I am working from home and I didn't drive my 2016 Civic LX 2.0l (Automatic transmission with 10,2000 kms on it) for a few days. But yesterday, I decided to go...

I know what you're thinking, "Another spark plug thread? Really?" :doh: Yes, really. Everyday we seem to receive inquiries from customers regarding which spark plugs he/she should run in their 1.5L Turbo Honda. As these cars become more commonly modified these questions are going to continue...

I recently bought a new 2018 Civic Sport and have been doing research on if there are potential mods that can increase performance (outside of tires and suspension) without messing up my warranty. From this I have learned that no mods like this really exist so I will have to be patient if I want...

I'm sure this has been discussed, but I haven't found a link. I realize that the Civic uses the MM system, but hasn't anyone figured out whether the maintenance will be different from the Turbo vs the Non-Aspirated versions? Just trying to get my head around it as a potential buyer looking at...
