Clarendon Specialty Fasteners, Inc. and ITG continue to develop a range of intake systems and air filters for racing and other high performance applications.

We currently offer intake plenums and airfilters for both 4 cylinder and V8 engines. Our plenum assembly not only weighs less than anything else currently available (see chart below), but also offers a substantial increase in horsepower. Our unique air horn design creates greater airflow to the injector, allowing one to burn more fuel and create more horsepower.

Our intake systems are currently specified by Ed Pink and Earl Gaerte for their championship-winning engines. Our air filters are manufactured exclusively for us by ITG - the leading air filter supplier to F1. ITG filters incorporate the lightest, highest flow, most efficient and durable foam currently available.
