NKG vs BOSCH spark plugs
bmw 318i 1994
A few months ago i replaced my spark plugs with NKG ones, since then i get a slight hesitation now a again when driving, but not idling.
Could this be from the spark plugs?
I bought some Bosch super plugs the other day, as a garage recommend that i change them due to the cheap spark plugs don't have the right charge or something?
