I've got one on the Shelby and one for the Lightning. So far after 500+ miles on a stock shelby with stock programming no CEL's. Went with grabber blue to match the valve covers.

Nice, I'm definitely getting a couple to replace the 7 miles of lines, fittings, and two canisters. They remind me of the Andair check valve that I had on my first '03 Cobra.

I run a CFM breather on my blown 3v. Deleted the PCV, put on the CFM and got some oil weepage from pressure build up. Hooked the PCV catch can back up, still using the CFM oil fill breather and everything is good again.
