so its time to change my plugs. which spark plugs should I use? the OEM ones or go with aftermarket ones? and if aftermarket plugs which ones would you recommend. im not highly modded as u can see in my sig and I only occasionally drive her hard for fun once in awhile.

btw I have an Evo IX SE....so ill need plugs compatible with an IX since I heard VIII and IX evo's use different plugs is this true?

thnx
