Don't the NGK's have a .6 tip as opposed to denso's.4?

 

 

Did you read the thread you linked? That chart is more or less garbage if you go by what everyone in that thread is reporting. You shouldn't be running the TR5 in any lightning, let alone one with more boost than stock.

 

Yes but it was long ago and everyone gave different opinions I just posted for you to make your own desicions!

 

Thanks fellas!

I went for the NGK TR6-IX irridium plugs. I will let you know once I go through the battle of installing them.

CHEERS!
