NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Anti-seize can act as a lubricant, altering torque values up to 20 percent.
My 500 sport rocked copper cores good for 30k and at 38k, when I bought it, was misfiring like mad and stumbled a ton at startup, swapped $14 a pop NGK Iridium IX Plug Number DCPR7EIX and runs like a dream
Get ngk cold start and gap them to .28? If I remember correctly for stock ..don't just drop them in
I ordered NGK plugs gapped to factory spec (.032). I didn't pre-check them, but I late went back and checked them and they were all in spec.
replace the plugs with NGK only... I did this on 21 cars and every time the car started working as a new one. All cars were Audi of course.
I just changed all four NGK platinum spark plugs on my soul. My car’s driving good. No engine skips.
I bought 4 new NGK plugs (part #92411). Installed them and it ran perfect.
I have the ruthenium. Bought pregapped from Mountune. They are fine. They work no noticable change. I've put about 200k miles on them between by ST and RS and changed every 50k miles with no issues (both tuned and stock).
I’ve gotten fake NGK on Amazon before it’s very possible
Also dont use plugs for tuned cars if youre not tuned. Tuned cars run colder plugs. They are not the same dont listen to some of these comments lol
