RECTANGULAR AIR FILTERS

Customized Fitment for Performance Carbs Standard round filters often can't match the specific mounting and clearance needs of performance induction systems. Our rectangular selection is engineered for the most popular carburetor platforms:

• Weber IDF & EMPI HPMX Series: We stock dedicated rectangular air cleaners for 40, 44, and 48mm IDF-style carburetors. These units provide the high-volume airflow necessary to satisfy large-displacement engines without creating a bottleneck.

• Progressive 32/36 DGV & DFV: Specifically designed for the 2-barrel progressive series, these filters ensure that both the primary and secondary barrels have an unobstructed path to fresh air, optimizing both fuel economy and power.

• Versatile Height Options: Every engine bay is different. We offer filters in various heights, including 1-3/4" and 2-1/2" tall versions, so you can find the perfect balance between filtration surface area and deck-lid clearance.

Engineered for Durability and Protection Our rectangular air cleaners feature high-quality chrome or polished finishes that provide a professional, show-ready look to your engine. Beyond aesthetics, the high-efficiency filter elements are designed to trap harmful debris before it can reach your cylinder walls. We also carry the essential service hardware, including replacement elements, hold-down clips, and 90-degree breather fittings, to ensure your induction system stays sealed and reliable trip after trip.
