Pick & Pull has this lower profile one. I've since put a slightly taller one on and plumbed the filter on the opposite side of the engine. They look almost identical, but the latest one is about an inch taller. I thought the super low profile one I had on was restricting the airflow. They both came off those Jeeps Cherokees with 5.2's & 5.9's. I cut off and used a small section of a second air box as a go-between connection for the K&N.
The flange height of the stock beer keg manifold and the Hughes Airgap is virtually the same once the throttle body injector flange adapter is bolted on. I'm running all Hughes Big Gulp throttle body, ported Airgap and hand blended & Super Prep'd chamber CNC'd and decked Eddies with a small Hyd roller spec'd by Dave. It's all managed by an SCT tuned factory ECM and Hotwire Harness. It's the only way to go. Plug and play baby!
