i know there is a diffrence bewteen the turbo plugs and plugs for an n/a. but what exactly is the diffrence?

 

There is no difference.

 

there should be no difference, they both use the same heat range spark plugs from the factory. the ONLY thing i can think of is that MAYBE the TIIs came with the platinum spark plugs stock, but doubtful.
