Our Roto-fab air intake system for the ZL1 features a new air box design, MAF housing and inlet elbow unique to the ZL1. The air filter itself is the same one we use with our other Camaro intake systems. Like our previous systems, no modifications to the vehicle or its components is required. Further, NO TUNE REQUIRED! We have carefully designed this system to work well with the stock calibration. That being said, our large duct size, generous air box volume and oversize filter are up for the task when power additives are introduced. Please allow a 2 week lead time for automotive painted finishes. *Inlet elbow and MAF housing are available with a carbon fiber hydrographics finish for an additional charge*
