Show original supplier description

The MAPerformance fuel upgrade kit provides a complete fuel system enhancement to support up to 500whp on E85 or 650whp on 93 octane for 2008-2015 Mitsubishi Lancer Evolution X models. The kit includes ID1300X fuel injectors featuring stainless steel internals for durability with alternative fuels, an authentic Walbro 450lph high-pressure fuel pump, and a billet 40-micron inline fuel filter. These components work together to ensure consistent fuel delivery and protection for your engine. Please note that this kit requires modifications to the vehicle's wiring, fuel lines, and fuel module. Due to the technical nature of these modifications, professional installation is strongly recommended. The factory fuel rail is not included in the kit, though an upgraded rail can be selected as an optional add-on during purchase. This product is not CARB legal.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
