Mishimoto Silicone Ancillary Kit Subaru WRX

The Mishimoto Silicone Ancillary Hose Kit is a direct-fit replacement for the factory rubber PCV and coolant hoses. It is also sold as a silicone ancillary hose set or engine hose kit. Mishimoto designed the kit to remove the weak points of stock rubber hoses and to improve long-term reliability in the engine bay.

Key Features:

• Made from four layers of silicone with heat-resistant embedded fibers for better pressure and heat tolerance
• Resists heat, pressure and oil degradation better than stock rubber components
• Includes silicone replacements for PCV and coolant lines that benefit from the upgrade
• Rated for a maximum temperature of 330°F (166°C)
• Each hose is built to factory specifications for an OEM-style fit
• Backed by the Mishimoto Lifetime Warranty

PCV lines are exposed to fine oil particles that slowly break down rubber and can lead to failure. Silicone holds up much better to this exposure. These hose kits suit daily driving, track days and other performance use. They are made by Mishimoto, a well-known name in performance cooling products.
