AIR GAP INTAKE WORTH THE MONEY?

I didn't watch the video but there are a ton of Chinese copies of the air gap... ( Not sure if he used a Chinese copy in the video) That don't preform as well as the Edelbrock air gap or fit as well... I had a stock 340 intake dropped a Edelbrock air gap on my car... I did feel the difference ( this was a on a bone stock 73 340 188 valve) low compression etc... I most certainly felt the difference in the seat of my pants... I'm also using that same intake on my stroker 340 build ( now ported ) with a hvh spacer
