Sport Camshaft GT Left – Porsche 911 3.6 250 HP (29860-L)

Improve the performance of your Porsche 911 3.6 250 HP with a GT-type sport camshaft designed for the left side of the engine. This camshaft is developed for performance-oriented Porsche builds where improved valve timing, better cylinder filling, 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 more efficient gas exchange and improved engine breathing. It helps enhance engine response, power delivery, and overall performance while maintaining compatibility with the original valve clearance setup.
