APR Carbon Stage 1 Intake System - Audi S4 B8 3.0 TFSI
The APR Intake system dramatically out performs the factory intake system and improves upon the closed box design. As performance increases, so does the importance of a high-flow high-quality intake system as a large pressure drop forms between the factory intake’s inlet and outlet.
As listed in the chart every combination of APR Intake Systems and throttle body pipes dramatically outflowed their stock counterparts. The APR Open Intake System with APR Ultracharger is roughly 35% less restrictive compared to the factory intake at 28" of H2O. By allowing the engine to breathe, the intake system lowers the intake air temperature, and allows for performance gains upwards of 17 AWHP at Stage 2+ (93). As performance climbs further, so do the power gain seen with the APR Intake system!
Finally I can hear the supercharger! This is a brilliant piece of kit, easy to install and made from quality parts. You will need an extra, small cable tie and some grease for the bungs on the bottom of the heat shield. Apart from that it’s just a few hand tools. I am running stage 1 and it’s definitely made a difference to the pull, sport mode is literally brutal! It’s expensive but at least it’s a noticeable change for your money.
Dead easy to fit and sounds great, not noticed any heat soak compared to original air box with K&N. My car does have an 034 motorsport intake pipe though - don't use the silenced original intake pipe!
Fitted this today, took about 15 minutes, really easy, just take the old air box out and this fits straight in, not only does it look amazing, but the whine you now get from the supercharger is a real head turner, I absolutely love it
