Description from rkautowerks.com:
Our RK Autowerks in house designed E70 X5m Intakes were developed using state of the art methodology followed by extensive road testing. A complete engine bay scan was taken to ensure fitment is perfect and all of the allowable space is used to increase the amount of flow introduced to the engine. The final product is a beautiful pair of carbon fiber intakes that can be installed without any irreversible modifications to the vehicle.
Not only are the intakes aesthetically appealing, they also provide real world performance benefits, 24WHP increase with a tune at peak power. Combine these with our ECU tune to yield a further increase of 50WHP/100WTQ.
