Spectre Coupler 4in. ID - Black - 97711

Spectre's EPDM/TPE couplers, elbows and reducers are available to help you connect different air intake tubes together with ease. We offer multiple length and shape couplers and reducers with 3, 3.5, 4 and 4.5 inch inside diameter sizes. These couplers are also offered with additional angles to match the direction you want your intake to route. Our EPDM and TPE couplers and reducers are not recommended for turbo-charged and super-charged engines.

Air intake systems are a common first mod to many project cars. They are quick and simple to install while also enhancing the looks of your engine bay, the sounds of your engine, and the performance of your vehicle.

Silicone hoses are a great upgrade from your OEM rubber hoses because they can withstand more pressure and can hold up to more heat cycles. Once you replace your rubber hoses with some quality silicone hoses, you shouldn't have to replace them again.

Since 1983 Spectre has designed and offered unique and innovative parts and components to fuel your car or truck obsession. Our products are designed and tested to perform and last. We have a state of the art chassis dynamometer with diagnostic and emissions testing and performance optimizing capabilities, as well as a top of the line Super-Flow flow bench with airflow, pressure, and velocity measuring capabilities in both intake and exhaust modes, and also a whole bunch of expensive scientific laboratory type equipment, all of which are used to develop Quality Products that Perform.

From humble beginnings in a two car garage, to setting world records and becoming the first wheel driven, gasoline powered car to run over 400 mph, it's been one heck of a ride.
