Spectre air intake couplers and reducers come in variety of shapes and sizes as well as three different materials.
The EPDM 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 Couplers/Reducers are designed for temperatures up to 385°F. These couplers & Reducers ARE recommended for use with forced induction systems.
