I have a set of 1 stage and 2 stage colder plugs for different psi of boost. Both NGK plugs. What do I need to gap them at? Stage 1 for like 10 psi and stage 2 for like around 15-18 psi. Thanks

.28 start from there then go down if needed

thanks

what turbo is this.

you can probably run your high and low boost on 1 step colder plugs

you willnt be able to tell untill you boost it

start at like .028 stated above, and if you get an ignition breakup, gap em down till it goes away. i am on 8's gapped at 0.018.

I am tuned on Chrome and the tuner said .032, but I heard so many different gaps that I wanted to make sure.

im at .026" for myself. starting at .028 and going down is a good idea. i have has issues with spark knock before gapped at .028+, but im running 1 bar +

OT....i have NGK BKR7ES plugs in my boosted GSR at 9psi gapped at .28....the idle has started to drop off recently and i have to boost the car in order to get it to run....does that mean the plugs are fouled?

I start at .035 on lower boost setups and only gap down if ignition problems present themselves.

I have an H22 right now running 15-17 psi (spiked once to 30...ouch!) with clean ignition and a .032 gap.

Its all about how healthy the electrical and ignition system are in your car.

do you have a weaker spark at idle? And if so, is there a way to make it stronger so that my car idles...the ignition doesn't break up in boost, but it doesn't seem to want to idle until after a hard boost...

My ride did that too. I got retuned and now it's fine. Not sure what was wrong though. But you weren't the only one. Good luck
