Howell Engine Developments Fuel Injection Conversion (California Legal) Reviews
Excellant upgrade to 1990 Jeep Wrangler 4.2 easy to follow instructions and everything was perfect fit
THE BEST UPGRADE ANYBODY COULD DO FOR THEIR 4.2L ENGINE. I INSTALLED BORLA HEADERS AND CAT BACK SYSTEM AT SAME TIME. THE DIFFERENCE IN POWER AND PERFORMANCE WAS AMAZING. ALSO LESS UNDERHOOD VACUUM AND WIRING GIVE IT A GOOD LOOK. ONLY PROBLEM I HAD WAS THE TP SENSOR GOT COOKED RIGHT AWAY UNTIL I INSTALLED SOME INSULATION OVER THE HEADER IN THAT AREA. NO PROBLEMS SINCE. STARTING PROBLEMS GOODBYE.
