Every engine that runs by internal combustion of fuel requires air to operate, and the more efficiently that clean air flows to the engine to burn fuels like gasoline and diesel, the better your engine performs. That's information you can find in the first chapter of any Engine Maintenance for Dummies manual, yet air filters continue to be one of the most neglected parts of an engine, even though air filters are an easily replaceable component of the air intake system.

Spectre Performance, with our universal clamp-on air filters, is doing our best to buck that needlessly, unproductive trend.

Whether you are looking for the perfect clamp-on air filter to finish your vehicle's air intake, or a more cost effective replacement to the one you have, or if you need a filter for your generator or pump's air intake - we have you covered.

Spectre's multi-size flange, clamp-on air filters are specifically designed with inserts, so they provide you the flexibility to use them for 3", 3.5" and 4" flanges. These round, tapered cone style replacement air filters are pre-oiled at the factory, so they're ready to install. They have an inverted air filter top for a larger filter surface area resulting in higher air flow potential and a longer service life. Spectre's precisely prepared air filters feature a highly efficient, synthetic filter media, with select number of filter design options available in a choice of red, blue, black and white media.
