ngk bpr7eix iridium spark plugs

[ralstonj]

I have an 2004 evo8 and was wondering if i have to gap these plugs and to what gap?

Do not gap Iridium plugs, you risk damaging the tips. They should be pregapped to run what you need. Next time save a grip of cash and buy the BPR7ES copper plugs.

i got them at cost. so they were only 18.50 for the set of 4. so Installing these plugs should be a breeze since they are pre gapped

[Evolvd]

Yup, drop em in and you'll be set.
