    Spectre air intake couplers and reducers come in variety of shapes and sizes as well as three different materials.

    The EPDM/TPE is a soft and flexible rubber while the PVC material is rigid and not flexible at all. These two types of material are great for typical cold-air intake setups and stock systems, however they are not recommended for forced induction systems such as superchargers or turbochargers.

    The Silicone material is manufactured using high quality silicone with a 3-layer polyester reinforcement. Silicone Spectre Air Intake Couplers and Reducers are designed for temperatures up to 385°F. These couplers & reducers are NOT recommended for use with supercharged and turbocharged systems.

    9776 - Spectre Air Intake Couplers and Reducers is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Perfect fit! I purchased this coupler so I would be able to use a couple different sizes of air filters on the 2004 5.3L Vortec LM7 that I put into my 1995 Jeep YJ rock crawler. It fits snug over the intake inlet and holds tight with the supplied band. It holds the weight of the 6" Spectre cone air filter and the MASS Air Flow Sensor.
