The N55 is a powerhouse, capable of producing over 600 horsepower on stock internals, but it has weak points. All that power requires almost 3x the boost the N55 was designed for. While the engine can handle it, your charge pipes may not be so strong. After over a decade, your BMW's stock charge pipes have become brittle and prone to catastrophic failure. Every time you press the throttle and hear that turbocharger spool is an invitation to the broken BMW club. Luckily, Mishimoto has a solution with our BMW N55 Performance Aluminum Charge Pipe Kit..----The Mishimoto charge pipe kit for your 2011-2018 N55-powered BMW adds durability to your charge air system, whether it's a stock daily driver or a 600 horsepower tuned monster. This aluminum charge pipe kit replaces your stock plastic pipes with durable, mandrel-bent pipes, long-lasting silicone couplers, and CNC-machined aluminum quick-disconnects. Our quick-disconnect flanges are CNC-machined to be perfectly round and far stronger than stock plastic parts, preventing boost leaks and unexpected failure. Replacing both the throttle body pipe and the intercooler pipe creates a reliable system, with no plastic parts to become the weakest link. To add even more reliability, we've joined our two pipes with a durable silicone coupler that easily withstands increased boost pressures.----Perfect fitment is a priority at Mishimoto, so we include all bracketry needed to keep your intercooler pipe where it belongs. Finally, a job worth doing is worth doing right, so we've included new charge pipe O-rings and quick-disconnect clips to save you time and a trip to buy more parts. Like all our BMW performance parts, this 2011-2018 BMW N55 charge pipe kit is backed by our Mishimoto Lifetime Warranty. So, if pressing the throttle of your N55-powered BMW leaves you with more anxiety than joy, install the Mishimoto N55 performance aluminum charge pipe kit to bring the joy back to your ultimate driving machine.
