Fits on all Porsche 986, 996, 987, 997 models EXCEPT 2.9L (multi hole crank pulley pattern), DFI engines, GT2, GT3 and Turbo.

Increase your engine output by reducing the draw of the engine's ancillaries ie the power steering pump, Air Conditioning, water pump and alternator by slowing them down and reducing the horsepower they use.

Underdrive pulley is one of the cheapest returns for the money spent when it comes to actual performance and horsepower gains for track and street use cars.

Installation tool (wrench) included, new OEM washer and crankshaft pulley bolt is recommended but not included with this product.

Please add Drive Belt for Under Drive Pully cars WITH Aircon Porsche 996/ Boxster 986/997 99610215199/1
