Direct bolt-on replacement for the restrictive Porsche factory air box cover-lid. The Fabspeed CUP airbox cover-lid 100% guarantees and provides increased airflow and power. Made from anodized  champagne gold CNC machined billet T6061 Aluminum. The gold color resembles the factory Gold Cadmium plating / yellow zinc plated OEM hardware that Porsche used in all their air-cooled cars. Its a awesome beautiful performance upgrade for all 911 3,2 liter Carrera cars worldwide. 

The design of this airbox cover was inspired by factory Porsche Cup Cars. After much on-track testing done by Fabspeed’s Owner on his 993 RSR, he found that using this open filter design netted the best power results, with more flow and cool intake temps.


The factory Carrera airbox cover-lid is designed to muffle and reduce the induction note of the 911 Flat-Six engine and simply hold the air-filter in place. The Fabspeed billet aluminum CUP airbox coverlid immediately lets the glorious air cooled flat six induction system breathe and even emit growl into the cabin.


With just this simple modification we saw a 7.2 horsepower increase over stock thanks to increased airflow.
