Porsche 996 GT3 BMC F1 Replacement Air Filter (1999-2005) Exhausts The design of this airbox

The design of this airbox cover was inspired by factory Porsche Cup Cars

The factory 994 "911" Carrera airbox is designed to muffle and reduce the sound the induction note of the Flat-Six engine to keep it quiet period

It retains stock OEM Porsche rear 911 Turbo 930 mufflers so the car looks original but sound and performs great

Paired with a Maxflo Exhaust at 6600 RPM there we saw an increase of 13 whp and 10 ft/lbs of tq and these gains are carried throughout the rev range for great under the curve power

The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light
