Thanks for the input George. I did not enplane the project well.

Started with a K & N off the shelf filter with the filtered top. Then removed the filter area, free handed the new 9" center, polished the edge, taped the edge, bead blasted the remaining center and shot it with DP-90. Then installed the GTS to match the car's Euro GTS pedigree. The center bolt was a SS flat allen head recessed into the lid so I could keep it white using the original GTS emblem material.

The trick was to lower the base because it is raised. Looking for something that would hold the outer filter surface flat and allow me to press the center lower took some looking. Got lucky by using a rear Pantera rotor which was the correct DIA and held the filter mating surface flat and then used an old Pantera axle with studs which held the axle in the center hole and then pressed it down. It worked remarkably well to lower the filter overall.

Removing the filter was a project though. It was glued in with what appeared to be urethane windshield adhesive---it was a bitch to get it out.

One could build the entire top using a thicker 11" blank and turning the filter area into the bottom and then machine in anything you want if your pockets are deeper. This was an effort to make a smaller filter not intrude into the deck and keep it as low as possible.

The 9" new center can be made in any look someone wanted just buy having an emblem made which is a bonus for individuality.

I have fought with filter ideas and shapes for years and the reason is a story by it's self. Air flow was explained to me in depth by someone with allot of racing history and why things work better or not. I sat in his office for several hours and talked about his history which I'll never forget---great guy.
