Magnacore 8.5mm & NGK BPR6ES???

[kareem17]

I just received my new Magnacore 8.5mm wires and NGK BPR6ES spark plugs the other day. Do I need to gap these plugs? if so how much? and how to do it?

yea, more likely than not you'll need to gap them ( or at least see if they're gapped correctly). Check ngk website for correct gap size, and there's a tool for measuring gaps, pick one up at your local auto parts store, it's probably gonna be by the checkout.

.028 - .032 the lower the gap the higher the boost

i gap at .028 with my b16g at 16 psi and its fine.. stock i'd say .029-.030

NGK's website doesn't say the gap size for my 97 eclipse gs-t... but since I am currently running stock boost I should gap at .029-.030. Do you think that I will notice a difference? Thanks for all the help.
