Smooth mandrel-bent tubes deliver more air to your engine while reducing boost pressure loss resulting in quicker turbo spool and more power.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003eBanks Boost Tubes are the largest charge air cooler pipes in the industry measuring in at a full 3.5 inches. Every other competitive product on the market tops out at 3.0 inches, and your factory pipes are only 2.5 inches with crushed bent corners and flimsy plastic components. By contrast, Banks Boost Tubes are made of high-quality aluminized steel for maximum strength and durability. With Banks Boost Tubes' smooth bends, your turbo can spool quicker thanks to improved boost pressure retention for maximum horsepower.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy It's Better\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eBANKS BOOST TUBES FLOW BEST\u003c\/strong\u003e\u003cbr\u003eBanks oversized charge air cooler pipes and a unique billet intercooler adapter results in less boost pressure loss from turbo to intake manifold.\u003c\/p\u003e\n\u003cp\u003eWith an \u003cstrong\u003e87% improvement\u003c\/strong\u003e in airflow, your turbo can spool faster and sustain boost pressure with less wasted energy and heat.\u003c\/p\u003e\n\u003cp\u003eBanks Boost-Tubes allow your engine, and specifically your turbo, to work less hard in compressing intake air; this maximizes horsepower delivery while reducing engine stress.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/shop-banks.s3.amazonaws.com\/products_data\/l5p_boosttubes\/25999_Dmax_17-19_FlowImprovement_SQ.gif\" alt=\"Banks Power, Boost-Tube, Flow Chart Results, Banks Power Boost Tubes, Boost Tubes for L5P Duramx\"\u003e\u003c\/p\u003e\n\u003ch2\u003eINDUCTION PERFECTION\u003c\/h2\u003e\n\u003cp\u003eAt Banks Power, our goal has always been to out-perform stock, our competitors, and even ourselves.\u003c\/p\u003e\n\u003cp\u003eFitting a full 3.5\" charge air cooler pipe through the existing engine bay compartment of your L5P was no easy task, but we did it.\u003c\/p\u003e\n\u003cp\u003ePut side by side with the factory piping, ours could practically eat the stock one whole, all while smoothing out tight bends and improving outflow.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e\u003cimg alt=\"Banks Power, Boost Tubes, Charge Air Cooler, Comparison vs stock\" src=\"https:\/\/shop-banks.s3.amazonaws.com\/products_data\/l5p_boosttubes\/25999_Hot_Side_Graphic.jpg\" title=\"25999 Banks Boost Tubes vs OEM L5P Boost Tube comparison diagram\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eGOING THE EXTRA MILE\u003c\/h2\u003e\n\u003cp\u003eOne of the keys to our high performance comes in our unique cold side billet intercooler coupler.\u003c\/p\u003e\n\u003cp\u003eOur engineers used CFD simulations to design the perfect taper to maximize airflow and reduce restriction and drag at the connection point.\u003c\/p\u003e\n\u003cp\u003eThe shape and curvature of this coupler is critical to maintaining the pressure efficiency throughout the intercooler system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e\u003cimg alt=\"Billet Charge Air Cooler Coupler\" src=\"https:\/\/shop-banks.s3.amazonaws.com\/products_data\/l5p_boosttubes\/25999_Billet_Clamp_ThreeQuarter.jpg\" title=\"Banks Power unique billet coupler\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eDO IT RIGHT\u003c\/h2\u003e\n\u003cp\u003eWhether you are looking at the cheap OEM plastic intercooler return pipe that's prone to cracking and failure, or the undersized alternatives from the other guys, there really is no comparison.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e\u003cimg alt=\"Banks Power, Boost Tubes, Intercooler Pipes, Charge Air Cooler, Banks vs Stock\" src=\"https:\/\/shop-banks.s3.amazonaws.com\/products_data\/l5p_boosttubes\/25999_coldsIde_v_stock.jpg\" title=\"Banks Charge Air Cooler vs OEM L5P intercooler pipes\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":43884074106958,"sku":"25999","price":598.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/0704\/5454\/files\/Screenshot2026-07-06225017.png?v=1783403529","url":"https:\/\/jkcperformance.com\/products\/banks-25999","provider":"JKC Performance LLC","version":"1.0","type":"link"}
