i have been running bosch platinum +4 spark plugs in my ls/vtec (they came in with the motor, i didnt buy them) and i have been reading about plugs and everybody on here says they suck ***. so i need to know should i buy plugs for a b16 or plugs for a LS. i dont want to buy thw wrong ones and have my pistons slam into them. oh yeah it has pr3 pistons in it. i plan on buying NGK coppers unless someone suggests otherwise. thanks for your help

 

get LS plugs. Got them for my friends franky and it's fine.
