COMP Cams part # 689-199-13 is a FSL™ Series Camshaft for GM L99 Engines like the Gen V (2010-15) Camaro SS. It is available via Marken Performance and yields +30-50 HP gain with no reprogramming required. This camshaft offers drop-in convenience, with no valve spring change required. It also features unique profiles on switching and non-switching cylinders for compatibility with Active Fuel Management systems and as a result it is certified emissions compliance in all 50 states with EO# Pending which all helped earn Comp Cams the Best New Street Performance Product Award at the November 2017 SEMA Show.
