Is this your bush?
i got my plugs at .35 and im just wondering if id be better off running them at .30? any benefits from this. It seems like the truck isnt accelerating as fast anymore! I got the original plugs back into it took out ur5 ngk. ive got a ticking coming out of the tail pipe now since tail pipe was put on it as its running but no smoke on start up! Bad valve? 81000 on the ty? Anyone got some simple checks i could do? Let me know¡
