Jeep 4x4s traveling along a trail can literally cook a meal on their intake manifolds!  I know, Kevin Carey and I had hot dogs grilled in aluminum foil between the intake manifold and heads on his JK Wrangler.  Between Loon Lake and our lunch break on the Rubicon Trail, they were fully cooked!

I seldom promote products at the forums.  Here is an exception:  DEI has just released new injector covers that would be very helpful for vehicles subject to crawl pace trail running and rock crawling conditions.  Here is the press release and photo...This is not a paid advertisement: 

DEI Introduces Heat Reflective Fuel Injector and Sensor Covers
Prevents Vapor Lock and Heat Soak

Avon Lake, Ohio (February 8, 2016)… Excessive heat can cause performance and factory fuel injectors and sensors to be at risk of vapor lock or heat soak which can cause rough idling, slow starting or other potential serious engine problems. Also, cooler injectors perform more efficiently with a more consistent throttle response.

DEI has now introduced heat reflective Fuel Injector and Sensor Covers that are available in packs of two, four, six or eight, that efficiently reflects direct and radiant heat away from injectors and sensors. Constructed of high-temperature rated glass fiber material bonded to a heat reflective aluminized material, DEI’s Fuel Injector and Sensor Covers work well on most any engine configuration with stock or aftermarket injectors and sensors.

The heat reflective covers are made with a split design allowing each to wrap around the individual injector/sensor and then secured with a sewn-in hook and loop fastening edge. There is no need to remove the injector.

·         Part# 010380 – 2 pack

·         Part# 010381 – 4 pack

·         Part# 010382 – 6 pack

·         Part# 010383 – 8 pack

For more information about DEI’s Made in the USA Fuel Injector and Sensor Covers or other thermal protective products, visit www.DesignEngineering.com, call DEI at 800-264-9472 or e-mail: Sales@DesignEngineering.com.


This could help on EFI/MPI Jeep engines and other trail runners that roast their fuel injectors while crawling off-pavement.  2.5L, 4.0L, 3.8L and 3.6L Jeep owners take notice!
