just wondering what spark plugs you've been using? have you stuck with the stock ones or gone a little colder like a BKR7ES-11

 

...

 

I use the bkr7 being they have 4 electrodes compared to denso's single tip.....You would think you'd have a better chance of not blowin the plug out having 4 tips to the denos's 1. My .02

 

I am running IK24. This is not for the nitrous but more so for my pulley setup. There is not really a big need to go colder on the plugs because the nitrous cools the intake charge.

 

Wheres my SAFC biotch.

 

Any new ideas on this topic?

 

IK24s should work fine. You could go to NGK for a little more electrode heft & less $$. I'm thinking, for my car, going colder yet. 18f this morning, IK24s , no problems. I won't change out plugs till spring but I realy think for my car they can be IK30s. For nitrous 30s would be my choice.

 

He's running injection not cooling.

 

That is how it was explained to me by one of the guys at detroit tuned. I was running 19%+4% with 75 shot nitrous. The guy said not to go colder than 24.

 

My $2 NGK work good enough for me

 

If the 24s arn't burning up that's good. Running NOS makes a ton of combustion heat. I've seen more melted ring lands running nitrous, not to mention big time blows. You can't afford to have a misfire either, trust me on this I've had a NOS car since 85 ( still using a button, owned this car since 69 ). At 1 time I ran N2Gs = very cold for regular street driving.
The coldest plug your driving & ignition can stand is best.

 

NX recomends a colder iridium plug with a single electrode.
