I'm just running the stock pulley and was wondering if most of you guys changed your spark plugs???

The stock plugs seem fine but I was just wondering if I was missing out on some performance by not upgrading....

Thanks guys!

I would say yes change out your plugs. At least one step colder now that your boosted.

Ok well I just want some safe and one-step colder quality plugs. I'm running the stock pulley. What do you guys recommend?

Thanks

and btw I did lots of searching and theres lots of debating.....
