Brand New Dinan High Flow Cold Air Intake, Carbon Fiber Intake Ducts (Part #D760-0038). Efficiency & maximizing the potential of the stock intake design were the keys to development for this N55 intake. Our sealed system delivers as much cold outside air as possible to the engine via an optimized carbon fiber tube that mimics the stock pipe but with less resistance with a straighter freer flowing design. The increased amount of air feeds into a larger volume airbox complete with a larger filter that elicits a sporty tone that makes the intake sound as good as it performs. This optimized design yields up to an incredible 10HP & 15 lb-ft of torque even without any additional modifications. Simply perform the short bolt-on installation in under an hour & enjoy a more powerful & audibly satisfying driving experience.
