waste of money to replace IMO. mine BLEW off when a stuck FPR grenaded my intake a couple years ago. i didn't replace it and 40K miles later i think the car runs better than ever..i agree about the heat trap. i am in Texas where it gets pretty hot...

And I thought they were engineered to enhance air flow around the nylon intake........

I bet you have a CAD model showing the thermal analysis on that don't you?

Isn't that why they call it,..... thermoplastic?

Lemme guess John, you leave yours on so you can't see the head bolts starting to pop out? =0)

SuperGlue is my best friend.
