Designed to cope with the slow starting and ragged idling that overheated fuel can cause, DEI Jeep Wrangler parts (from Design Engineering Incorporated) include advanced fuel rail and injector cover kits. These DEI Jeep Wrangler parts cut down on vapor lock problems and give your Wrangler much better throttle response, making the injectors work a lot more smoothly. These parts, made to work on L6 engines, are a mix of heat-reflective aluminized material and glass fiber that can stand up to high temperatures. These components attach with a hook-and-loop, Velcro-like attachment, so that you can fit them to your Wrangler's engine and start getting their benefits almost instantly.

Fitment Includes:

  • Rubicon, Sahara, Sport S, Sport, Unlimited, Islander, Rocky Mountain, Renegade Wranglers
