Do I need new plugs w/ 2.93 and Predator?

[Grey03]

If I get a 2.93 pulley and a predator do I need to get new plugs?
If so what do you guys recommend? What about idler's?

Thanks for the help.

I would definetely swap out the plugs. I like Autolite 103s. With the 2.93 pulley gap them at .035 or .030.

As far as an idler, i made 450rwhp with a 2.93 predator and catback with no idler or slip

i mean if you want sure, you can swap them but you dont have to. i have my stock plugs on my car and im running a 2.80
