Exact fit improved JB Performance billet aluminum impeller is a direct fit replacement clockwise impeller wheel. JB Performance F1A billet wheels are professionally designed to replace OEM ATI ProCharger F1A style impellers. The blades must curve in a counter-clockwise pattern.

Our impellers are professionally designed by air flow engineers that already design turbo wheels. These wheels are professionally 5 axis machined and zero balanced on a CNC for a precise build quality. After machining, they are crack checked for defects with an x-ray, then anodized and logo etched for a perfect wheel that almost looks like art!
