(aFe) produces high flow, high performance air filters \u0026amp; intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. We are a team of engineers, machinists, production and sales people who believe in the product we design. We each have years of experience in our respective positions and together work to ensure that we have the best product on the market. Our purpose was not just to be another vendor that offers air filters, we chose to pay attention to those finer details that set an aFe filter  apart from the competition. We currently offer aftermarket air filters for passenger cars, light trucks and SUVs. We also have many applications for round racing and universal clamp-on filters.

Designed to be a one-stop drop-in kit, including all fasteners and gaskets needed to make installation quick.\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCast iron construction with 65% thicker walls for increased toughness and resistance to cracking\u003c\/li\u003e\n\u003cli\u003ePredrilled pyrometer port on driver's side manifold for easy sensor install\u003c\/li\u003e\n\u003cli\u003eSold as a complete kit with gaskets and fasteners for easy install\u003c\/li\u003e\n\u003cli\u003eEfficiently transfer exhaust gases to the turbocharger\u003c\/li\u003e\n\u003cli\u003eHigh Temperature Paint For Corrosion Protection\u003c\/li\u003e\n\u003cli\u003ePredrilled Pyrometer Port On Driver Side\u003c\/li\u003e\n\u003cli\u003e5 Percent Increase In Flow\u003c\/li\u003e\n\u003cli\u003eCast Iron Construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation \u0026amp; Documents\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/ab952de84528e598d00587955d5c8a12L.JPG\" target=\"_blank\" rel=\"noopener\"\u003eTechnical bulletin\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/f3098924dc147616552c55214bb0a167L.JPG\" target=\"_blank\" rel=\"noopener\"\u003eTechnical bulletin\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BD Diesel","offers":[{"title":"Default Title","offer_id":67746778153112,"sku":"BDD1041459","price":535.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/8567\/1064\/files\/69090d4eb3111adc8f89dfc70fe3fd7cL_8a47a682-1715-45c7-8936-b459298674ed.jpg?v=1792285051"},{"product_id":"bd-diesel-01-16-chevrolet-gmc-2500hd-3500hd-6-6l-duramax-passenger-side-exhaust-manifold","title":"BD Diesel 01-16 Chevrolet\/GMC 2500HD\/3500HD 6.6L Duramax Passenger Side Exhaust Manifold","description":"\u003cp\u003eBD Diesel Performance is unique among its peers in that it designs, manufactures and distributes a wide range of products specifically engineered for performance diesel applications. Located in Abbotsford, British Columbia, Canada, BD's state-of-the-art facility covers 65,000 square feet, and employs 60 plus highly-trained individuals.
