changing spark plug's in a 2007 997 gt3
how often should these be changed? i have 16k miles (55 track days) on my car and i guess 1/3 track and 2/3 street mileage.

I believe the manual says 30,000.00, Its in the book.... If you track the car i would do it at 15,000 or so, BTW, just talked to a fellow rennlister today how had to replace his head because the plug worked loose and striped it out during a recent track day, Went home early. so make sure they are tight.
