The AV6 blow off valve (AV standing for atmospheric valve) is the result of hundreds of man hours between CAD design, prototype building, bench testing and vehicle testing. Many months of R&D has gone into our valve to produce a quality OEM replacement that makes a crispy clean sound and is 70% the size of it’s competitors. This valve, with a different base, was run for a few months on our 400 horsepower Elantra Sport, so you can rest assured it will perform for you.
The AV6 is designed to be a direct factory bypass valve replacement. No check engine lights, just a clean sound with solid performance. The body is machined from billet 6061 Aluminum, anodized black. The piston is brass and designed to be as light as possible for lightning fast response.
