A high performance air intake forty an automotive engine has an oiled gauge filter of inverted conical form, including an inverted, shaped inner apex, the filter fitting within an in-line filter body that forms a part of a slender intake line. The in-line form of the filter enables the pick-up of intake air from a cool zone below the engine, with little subsequent heating of the air, resulting in enhanced breathing of the engine, with observable performance enhancement.
