39 dollars for parts? Hopefully they aren't champion plugs. Hell of a deal
Champion copper plugs are great! Why change if they are working perfectly? Copper is a better conductor than anything other than silver.
I plan on doing the spark plugs soon just picked up NGK Iridium plugs.
I put in NGK Lazer Iridium in mine about 60k ago and they've been fine.
I had to pull champions that were hardly worn. NGK ran a lot better.
Personally I’m running EQT’s stage 1+ tune and I just went with the recommended plugs (NGK 4905s) for peace of mind. I think it’s worth the extra couple bucks for my sanity
I'm using oem ngk plugs changing every 2nd oil change so around 16,000km
When I started the vehicle up, it woke up really aggressive, there was a strong gas smell and it stuttered badly when driving her, along with the check engine light flashing at me when I did the test drive.\n\nAfter taking out the coil pack, I found that there was a lot of crap inside the springs within the boots...looked like dielectric grease gummed up by the previous owner. After cleaning all those springs and making sure they were straight, I took the new Spark plugs out (Champion Copper) I rechecked the gap and they were all good, after putting everything back together the old girl started up quick as hell, no shaking or anything. I drove it for 15 minutes and I had no issues whatsoever.
the guy said the spark plugs I used are the issues because they are champion brand and I needed to use NGK brand for my Acura
I stopped buying plugs from eBay and Amazon years ago after getting what I can only assume was a bunk set for my BMW. They looked the part, but caused the engine to run rough.
