Hesco High Flow 62MM Throttle Body for 91-04 Jeep Wrangler YJ & TJ with 4.0L

Our 62mm throttle body begins with brand new original equipment unit that is bored oversized to 62 millimeters. Greater airflow allows for increased hoursepower ratings. Results may vary but some dyno tests have shown horsepower gains of up to 15. There is also no core charge to worry about, as this is a new part. A 62mm Throttle Body Spacer can be added for addition power gains and a high flow air filter or filter kit can also be purchased for maximum performance. All 1991-95 Wrangler applications must purchase our Adjustable Fuel Pressure Regulator for optimum results.
