Silicone Adapters & Couplers

Building your own custom air intake or cooling system?  Trail-Gear is proud to offer the same silicone adapters and couplers that we use on our own Extreme Air Intake line.  We have the most popular sizes, including the hard-to-find 2.5” to 2.81” adapter that fits the Mass Airflow Sensor on the Toyota Pickup/4Runner 22RE engine.

Our silicone adapters and couplers are made out of 1/8” thick, polyester fabric reinforced silicone, which meets or exceeds SAE J20 Standards. These adapters and couplers can withstand temperatures of -20°F to 350°F.  Each adapter has a high-gloss black finish that will look great under the hood.

Caution – For air or coolant only. Not for use with fuel or oil.
