Description
The Mishimoto Silicone Throttle Body Hose, part number MMHOSE-SUB-ITBBK, is a black, 100-percent silicone replacement for the factory rubber throttle body hose that is prone to failure on the 2008-2014 Subaru WRX, especially on cars running increased boost. Built with five layers of silicone reinforced by heat-resistant embedded fibers, this hose is engineered to handle substantial boost pressure that the stock rubber piece was never designed to survive.
As a core piece of the vehicle’s air intake system, this throttle body hose routes charge air from the intake tract into the throttle body, so its integrity directly affects how well the rest of the air intake performs under boost. Mishimoto designed the hose with increased pressure and heat tolerance compared to the factory rubber unit, giving WRX owners a more durable link in their air intake system. A built-in position indicator takes the guesswork out of orientation, and most installers can complete the swap in under an hour. The hose is a direct fit and ships with mounting hardware, making it a straightforward upgrade for anyone looking to shore up a weak point in their intake plumbing.
