I know the 4L is picky about having the OEM champion plugs, how about the 2.4L? Last time I changed the plugs all they had was bosch platnum double tip. They seem to be fine but would the original champion coppers be a better bet?
What happens if you don't use the OEM Champs? Reason I ask: I just replaced the plugs with Champion Double Platinums. The ones I took out were NGK's. I figured the NGK's were stock. I bought my unlimited used with 36k on it (lease return) it looked like they were in there for a while.
