Innovative Interceptors is doing a group buy on locking God's Head Valve Caps for the Marauder. These are the units that SHOULD have come on our cars. My car was delivered with the chome caps missing already! These are chrome caps, with a polycarbonate top with the Mercury God's Head Finished in Silver over Black. Comes with 4 Caps and 2 Locking Keys in a Gift Case. This group buy ends Feb 28,2005. Check out theInnovative Interceptors on this site for more details on ordering.
