[silver2001cobra]

like the title states,this is the second plug that was blown out the head within 3 months.what`s the deal?the sad thing is ,it`s a fr500 head.Is there something i need to know about?what can i do to solve the problem?maybe i should get rid of the car,because this is becoming a pain.

fix it with a timesert...they are pretty damn strong...kit is a little pricy unless you can find a shop that has a kit...i think the kit is like 500 bucks...but you get lots of inserts with it...

4 threads own you is all i can say. Heli-coil/timsert, whatever only thing you can do unless you buy Jan 05 + cobra heads.

A FR500 keeps blowing plugs?

Either a bad head or wrong/bad plugs. Or even you're not tightening them down enough.

German torque spec Goodentite! I torque mine but only because I am anal about that kinda stuff...and I have a torque wrench. 7-14ft lbs if I remember correctly course that is for a stock head. Not sure if there is a difference with that FR500 unit.
