Which spark plugs

[97stanger]

What spark plugs should i look into getting for my build?

SQ SI upwards of 15psi, intercooled, 8 rib, forged internals 9.5:1, stage 3 PI heads, stage 3 blower cams

I went with 1 stage colder Motorcraft but you might need 2 stages colder like a lightning with your power levels.

maybe I would be best off asking my tuner

 

[DropTopPony]

I would ask and unless he is a vendor of a certain brand he will be honest.

most boosted owners i know use TR6s. 1 step colder and above average longevity. certainly not the best but bang for buck.
