.029-.031 gap 1step colder plugs
example; ngk brand bkr7eix

personaly i run 2 step colder with .029 ngk brand bkr8eix (they come pregapped .029-.030)...always check the gap to make sure but its pretty hard for them to get mishandled (not saying it cant happen) to were they will need to be gap'd more or less. most plugs are packaged with sleeves to protect the ground strap.

I run these cause of the amount of boost i was running (any given day may run 16psi which would put me somplace in the mid 300hp range on my t3/t4b garrett)

brett runs copper plugs...they seem to work fairly well for him.

irediums are "supposed" to last longer over all so i stick with them.

I was wondering... Those of you on 18-20 psi what are you running gap wise? And is anyone having spark blow out issues? Im gapped at .025 on my copper 2 step colder with E85 on 18-20 psi, wonder if i could go with a bigger gap, i was just afraid of getting spark blowout

problem is its gapped to .044...so you will need to regap it a bit closer... .030 should work, you can always adjust to what works best for your app..good luck

Gapping iridium is a pain esp extending the gap.. mine are gapped at 0.032 might need to gap closer as i up the boost

I've been wondering the cooper deal myself, wouldn't mind getting 2-step colder cooper plugs. I don't care if I have to replace them every 20-25k miles, heck I change the iridiums almost that often anyways (peace of mind)

BlackKnight

Not really, get some pliers and grab the metal end only and pull it open. This is how I do it.

Carlanga

also there are wire type gaping tools that do pull on the tab without having to touch the firing tip

You can run either, but I would not recommend bouncing between each copper and iridium. The tune requirements change for each plug.

Also, we sell both kinds at our store. Order with Ground shipment and as always, we overnight them for free!
