Description
The Mishimoto MMHOSE-SUB-ANC4BK Silicone Ancillary Hose Kit is a black, seven-piece replacement hose set engineered specifically for 2.5L turbo Subaru WRX and WRX STI engines. Built from high-grade silicone reinforced with heat-resistant embedded fibers, it’s designed to swap in for tired OEM rubber ancillary hoses while retaining factory fitment. This is a piece of true Mishimoto Fabrication work, purpose-built rather than adapted from another application.
Where factory rubber hoses degrade under sustained heat and boost pressure, this Mishimoto silicone kit is constructed to hold up longer, offering increased pressure tolerance over stock rubber while efficiently managing heat under the hood. The performance-grade silicone construction is rated to withstand temperatures up to 330°F, making it a durable option for drivers who want a refreshed, OEM-style ancillary hose setup without sacrificing fitment. The kit is offered in black, blue, or red, giving owners a way to match their engine bay aesthetic while upgrading hose durability — this particular listing is the black version.
Vehicle Applications
This ancillary hose kit is a specific fit for 2.5L turbo Subaru applications only. It’s compatible with the 2006–2007 Subaru Impreza WRX and WRX Limited, the 2006–2007 Subaru Impreza WRX TR, the 2004–2007 Subaru Impreza WRX STI, and the 2007 Subaru Impreza WRX STI Limited. Because fitment is specific to these 2.5L turbo motors, it is not intended for other Subaru engines or model years outside this range.
