    Spark plugs

    Just spent over $600 to get my plugs changed on my 04 fx4 has anyone dealt with their plugs breaking when removing them.

    It's a common issue so I'm told. Along with broken studs on the manifolds! Get it all done while your at it!?! I am looking to find time to replace mine, actually along with upgraded headers!
