So i have searched high and low and basically come up with a mess of information some right and some wrong, most of it you can not make two cents of. My question is i am going to run one step colder plug, which plug should I be running and where should it be gaped at ? this is my set up

red 27pounds
pump 93
and all the bolt ons

any help would be great !

 

BUMP...




For someone who also needs the answer..

 

anyone ?

 

Denso IKH24 try to gap around .023, if you get blow out up top, close the gap.

 

the stock ix plugs are more than capable with your set up...but if you insist on running something that is one step colder I'd call a few shops/tuners and get their opinions

 

not sure if you've read this thread

has one step colder suggestions

 

I run IKH24's stock turbo 28.5psi all boltons/methanol with a SparkTech NonCDI and .028 plug gap. I buy them from optionsauto.com for around 9.50 a plug and they work pretty good. If your on stock ignition I'd start at .024 and work your way down from there if you get misfires.

 

I recommend sticking with the stock plugs. I was running 40psi peak on the red with factory IX plugs gaped at .024 with no problem.

 

Denso's Iridium's 1 stg colder gapped @ .018-.022

I ran 42psi :P

I had the spark blow out over 30 psi on a set of Denso's that were gapped at .025" so I brought the gap down and the spark issue went away.

I buy mine from David@Horsepowerfreaks they're about 55 bucks shipped.

 

has anyone tried the autolite iridiums that autozone carries? They had them in stock heat range and one step colder for 6.99 a piece.

 

These are what I just ordered from MAP to go along with my SpoolinUp COP setup. They seem like the best option available for those of us wanting to go 1 heat range colder.

 

Go with the stock plugs. You do not need 1 step colder at that power of boost level. Adjust the gap as needed. Also try indexing the plugs to get a better fire rate. If you do go with 1 step colder plugs get the IKH24's.

 

dave from BR just emailed me back and said no point in running one step colder hum ?

 

With your turbo and mods it definitely won't hurt to go colder. The stock plugs are proven to be very effective though. It really comes down to personal preference and opinion.

 

okay so say i wanted to go a step colder which plug should i buy and where should they be gaped at ?
