If your running with a choke on your carb, check the distance from the top of your low profile air filter to the top of the choke horn. In my case using the 1 3/4" filter element the top of my "big oval" air filter cover was actually resting on the top of the choke horn. Believe it or not that restricts mucho airflow into your primaries. My short term solution was to use the 3/4 x 1/2" dense foam weather stripping with the adhesive side purchased at home depot. I layed a strip on the bottom and top edge of my filter element and which added about 1/2" of thickness once tightened down and compressed. This raised the bottom of the air cleaner top up off the choke horn and still has clearance from the hood. I do plan to have the choke horn milled off and live without the choke. I'm in a pretty moderate climate zone so this will just annoy my neighbors for a couple extra minutes when I take the car out. No problem right?

Chas your innovation looks good. I was under the impression that the small scoop on the Cobra hood act more like an exit for air because of the open snout and small side vents. I think your design would counter that.
