It don't really matter what plug you use because in the end your warranty does not cover spark plugs, was told this personally by the stealership yesterday and was quite pissed off seeing how the plug shot out of the head but my warranty still didnt cover it so id say go with what ever plug is gonna give you less **** down the road

 

I used Champion One piece plugs and they perform well. They correct a design mistake.

It REALLY P's me off when they don't fess up and correct their design mistakes. Their screw up should be a recall - not a big bill to the customer. That might encourage them to actually design something that works properly and not something that is designed to fail.
