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.
