What are the best spark plugs for a 98 eclipse gst. with intake, exhaust,1gbov,upper int pipe, running 16psi.
I have read on here that iridium plugs arent good for turbo cars. I just recently took the ngk iridiums out of my car and replaced them with ngk bpr6es and gaped them at .028. It's probably just in my head but the car seems to run a little smoother expecially at wot at high rpms. The iridiums seemed to peak at around 5000rpm. Has anyone tired the v-power or platinum by ngk or the bpr7es?
Any advice on what works the best would be great

 

see i put ngk iridium plugs in the gsx and they seemed very nice

 

NGK are the best

 

i agree the ngk iridiums are the best out of all the ones ive used in my gst

 

also next time try searching, you find results very very quickly on questions like this

 

If I have IK24's from my totaled 3000gt could I use them in my 97 GST? They only have about 1000 miles on them.

 

nkg bp6es for stock, ngk bp7es for 18+ psi
