is it worth my money to put iridium plugs in my 04 RX-8 it has the full greddy turbo exhaust and intake system

 

Use Rx7 plugs, u will get better respond.

 

Denso IRL01-27/IRT01-31

 

Yeah the Rx7 plugs are great. The Bur7eq and the bur9eq.

 

Im going to change my plugs soon but I think I have to stick with Factory plugs for now. Since I dont want them to give me any BS excuse saying that I install aftermarket stuff and voids the engine warranty.

If I dont have my warranty, I would use RX7 plugs for sure.
