Show original supplier description

The DSX Flex Fuel Kit offers a true Plug & Play solution that allows you to convert your 2009-2014 Cadillac CTS-V to use E85/ethanol-based fuels, supporting any blend from 0% to 100%. This conversion unlocks the potential for substantial power increases, particularly in boosted engine applications. The kit is equipped with an authentic GM Flex Fuel sensor and OEM connectors, ensuring seamless integration. The tubing is constructed from stainless-steel and is mandrel-bent for optimal flow. A plug-and-play wiring harness simplifies installation, and the package includes the GM Quick Connect tool, the sole tool necessary for fitting. While the kit can be installed prior to tuning, full advantage of ethanol-based fuel requires tuning software like HP Tuners or EFILive and access to a dyno or competent tuner. Once installed and calibrated, the ECM uses the sensor input to automatically adjust fuel and ignition maps for flawless drivability and increased power production without compromising engine reliability or safety.

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.
