Spark plug Bosch or NGK
newer Bosch plugs, cap, rotor (maybe 15k ago)
Don't bother with platinums. Just change out BKR6e plugs every 3-6k and you'll be good. They are dirt cheap and run the best.
Also, the best plugs for the car are NGK BKR7E's gapped at .032\" for unchipped and .028\" for chipped. They don't last as long since they're copper but at $2.39 a plug it's easy to afford to change them every other oil change. May not last the longest but they definitely run the best.
Recently replaced original spark plug wire set w/new Bosch; wire set, distributor cap, rotor, O2 sensor and Platinum spark plugs
So I went with the ever popular BKR7E plugs gapped at .028\". I bought a spark plug gapper and verified the gap which is a good thing because the BKR7E's come pre-gapped at .033\".
I think that the recommended plug (and original equipment) is probably a Bosch Silver plug, and that is what I would probably stick to if I were you.
i like the way it runs str8 out of the box b/c ngk says not to gap them
the car seems to run really good at the .028 with the bosch plugs
I am at 20,000 miles with my 07 VW GTI that has several modifications including a chip and I am about to change my spark plugs. I have heard many people say that the colder application spark plugs will work better for my car due to the fact that it is chipped. I went to the dealer and purchased the bosch #101-905-631-B spark plugs which the dealer recommends, but I dont know if these plugs are the colder application? Please give me your guys feedback on what plugs I should buy (Part #'s and website that I can purchase them from). I care about my GTI and want it to run the best it possibly can. I appreciate any feedback you guys can give!
everything else runs pretty poorly on our cars. especially the bosch +4's
