I finished my installed on the JWT TT 530, but I forgot to change my plugs, and I am getting a little lazy to look into the engine bay. will stock plugs hold up ok?

Thanks

 

Go with one step colder iridium ASAP. Don't risk your engine for such a small detail....

 

I will be going NGK one step colder, just wondering how bad it is. I am not experiencing any knock.

 

It depends on the tune and the boost levels being run. If you're absolutely postive it's not knocking while under heavy load and while heat soaked, then you probably don't have much to worry about. If you push your car hard on the track or for extended periods, they're not a bad idea for a little cheap added protection.

 

I just go to work and back, light to light pulls, and maybe highway when I am on it.

 

Just replace them it's cheap insurance.

 

I have spoken to JWT and they said they recommend it. plus my plugs are new, less than 10K on them. i will be on the stock JWT SS box tune, so pig rich.

 

With electronic ignitions, plugs go a l-o-n-g way. Depending, also, on the quality of the gas, they should produce a fine spark for thousands of miles.
If you know an auto electricity mechanic or, even better, an automotive en-
gineer, ask about this. Iridium IS the plug to go with, IF you actually need them.

 

any one have the part number on these step colder plugs?
