Next week my S3 will have a remap at SKN on stage1 and i read alot of threads
about spark plugs,but i still dont know what plugs would be the best for my car.
I started to feel some hesitations in 3rd gear (4500rpm) and i think my plugs are bad!
So,what spark plugs do you recommend for stage 1 for best safe performance?
The best place to buy?
Thank you all!
