The air coming into the box has been upgraded from 5\/16”holes to massive 1.5 inch holes letting as much air\u003c\/span\u003e\u003cspan\u003e in as possible. The stock lid and fuel breather line also fit this new filter base. I have ran these boxes on my land and sea water brake engine dyno and have posted the results in the pictures with various engine combinations. I HAVE NOT seen much gain on a bone stock engine but as you add things like timing, compression and exhaust I have then seen as much as a 1 horsepower gain, pay attention to the engine specs at the top of the dyno charts. These dyno results are with a 212 hemi predator stroked to 224 with a 16cc head 12.5 to 1 compression ratio. stock cam, and carb. The jets have been changed  to use e85 fuel on this test engine. I also suggest using glue or epoxy to make sure the box stays in place. You will receive the air-box 2 screws and a filter.
