the proper sparkplugs
right now my car is all stock x-cept the 1G BOV, UICP and FP re-wire and a hacked airbox with the stock filter
everyone said USE NGKBPR7ES Plugs so i have been!!
but they seem to foul out after like 500ish miles
so i did some research and found out that your only suposed to go 1 step colder if your running 75-100 hp over stock
so i bought the stock plug NGK BPR6ES and it urns much better, pulls harder idles smoother
when i got the car it had some cheepass autolites in there and i never had a comparison ftom the NGK 6 to the 7
but my findings is that for ME, the 6 seems to be better than the 7
thats just my exp. with the plugs, i thought it was kinda intresting,
does anytone have any other useful info to add thats along the same lines?
