Sport Camshaft GT Right – Porsche 911 3.6 250 HP (29870-R)

Improve the performance of your Porsche 911 3.6 250 HP with a GT-type sport camshaft designed for the right side of the engine. This camshaft is intended for Porsche performance builds where improved valve timing, efficient gas exchange, and a more dynamic engine character are essential.

Thanks to increased intake and exhaust cam lift compared to the factory specification, along with optimized valve opening durations, the camshaft supports improved cylinder filling and more efficient exhaust flow. This results in sharper engine response, stronger performance potential, and a distinctly sportier driving character while maintaining compatibility with the original valve clearance setup.
