What's wrong with stock plugs?

Well, when you are boosted you need colder plugs so that there will be less chance of detonation if my reading is right.

Most here run the NGK BRK7EIX which is heat range 7. Stock is 5, IIRC. So two steps colder.

I got the denso's becasue they are supposed to be a little better quality and at Amazon they were the same price as the NGK's.

Be advised that Denso has there own heat range system, so IK22 - heat range 22 which = heat range 7.

Denso makes TRD plugs to there specs based off the IK22 so that is why I went with the IK22's. HEck they might be the same as the $50 per plug TRD's. lol

Eh, I've yet to have any detonation issues running at a 14.7 AFR, so that should be even less of a problem after some tuning. Maybe I'll buy some for fun anyways

Btw, I like this I scratch your back you scratch my back thing we have going on lol.
