Spark plug Bosch or NGK
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.
For iridium spark plug. Do NOT gap them. I have bosch double iridium spark plugs and over 120K miles now. Still goes strong.
My car has Bosch Double Iridium spark plugs. Over 120K miles now still go strong.
I also added bosch sparkplugs 4 months ago, and also have some stuttering.
I tried Bosch plugs on a 1995 NG900. Problem as described. When they state compatible, that might only address mechanical fit. Stick with the original plugs
My brand new out-the-box WEN 3500 would barely start until I tossed the Torch and replaced it with an NGK. It now runs as designed. Too many others have had similar issues and that's why Torch is widely regarded as junk.
