ok so i have the trd scer, along with full megan exhaust and a 9.5 boost pulley and nst lite crank pulley, and other small items, so i was told the plugs u get with the trd scer kit are crappy, so what plugs should i be running?

NGK BKR7EIX Iridiums.

You will get the same results with either denso or NGK iridium. Both are stellar plugs. bkr7eix is fine although personally I would run an 8 heat range "bkr8eix" which is equal to the denso ik24 with your mods.

One thing I noticed on the tc under 10 psi, the car digs a wider gap. If you know how to gap iridium plugs "much different than a crap nickle tip" then set them to .040

awesome thanks guys, so are these actually different plugs than what comes with it? if so u think it will actually make any difference in feel?

whats the rule? how much hp = how much colder the plugs should be? Im pushing about 266-275. what plugs would you guys suggest?

Search Buttons great! =o)

1 step colder. I usually go around 1 step per 100hp gain which is a very "general" rule of thumb. Many other factors apply but the general rule works ok. You could go two and be fine. I am running 2 colder and it is perfect.

thanks

i did put in the ik24'a and i did notice a smoother idle and a better throttle responce,

anything inbetween shifts?

Might be a "dumb" question!...HaHa...Dont Our cars come stock w/ Iridum PLugs already????..

Crippie

Yes in a 6 heatrange. I also run an ik24 which is two steps colder gapped at .040

Crippie

does it come gapped at .040?

hotwheelsrs1

yeah but i am supercharged, thats y i started this post, and yes it is the colder plugs that do it, and apparently the plugs i got with the scer werent irridum, so it made the ik24s all the more better an upgrade

Yeah the sc comes with crap nickle tips. The iridium past a 7 heatrange usually come gapped at .032 unless it is an NGK and you order a wide gap, I changed mine to ,040 and it ran much better overall.

i have mine gapped at .26

No they are set at .032 if you order denso's. You have to use a feeler gauge set and bend the arm, not touching the iridium tip to gap them. A slide gapper will damage iridium plugs.
