I used a pipe flashing from Home Depot. It is made of a sturdy bu flexable blacl plastic. I then cut it to fit in right behind the filter. It stays in place on its own and seals out all the heat from the engine. i noticed that i can now touch the filter top after driving my car, so it seems to be doing the job. I am sorry I don't have any pictures but a few of the guys from the West Coast LLSOC have said that it looks like a factory item, it does match the plastic in the engine bay very well. I will try to get some pictures of it soon, in the car and oput of the car.
