If you prefer the better Fel Pro gaskets purchase kit # HUG 7720FEL If you need to repair the intake plenum gasket on your V6, it is available by ordering Part # HUG 7725. We always suggest replacing the thermostat with one of our premium stainless units available below under "Related Parts". Attention Dodge & Jeep Truck Owners!     Tired of the gasket blowing out on your plenum cover? Engine pinging under acceleration? Using an excessive amount of oil? Noticed that your mileage is dropping? Don't want to weld the cover to the intake?     Worried about turning up the boost on your supercharger? This is the answer! This kit will replace the plenum plate with a one-piece, high-strength, 1/4" thick aluminum plate. It is supplied with all new, fasteners, new intake gasket set & gasket, new intake bolts, new bypass hose and detailed instructions.        The factory tried and failed to fix this probelm by using a metal gasket. This is a short lived fix, at best. By using our 1/4" thick aluminum plate, the problem is solved no matter what type of gasket you use. Clues to help diagnose the problem: 1. With the engine shut off open the throttle body wide open. Look down into the manifold with a flashlight. This area should be clean aluminum - no oil or black soot. If there is oil (usually dirty black) the plenum gasket is leaking. 2. With the engine running, remove the PCV from the valve cover. There should be air pressure coming out of the valve cover. If there is a vacuum, this indicates the plenum gasket is leaking. There is an option:    For those of you that want to completely eliminate the plenum, improve your performance and increase mpg.....check out our  HUG 5409 FI Air Gap intake manifold made exclusively for Hughes Engines by Edelbrock Corp. This is a complete replacement intake manifold that eliminates the factory "keg" style intake.     One of our customers posted a really good article on how to install our kit.   Click Here for Product Instructions   Here is a link to a great video made by Matt Payne on doing this repair. CLICK HERE TO VIEW VIDEO   Also keep in mind that when the plenum cover gasket leaks, it causes oil to be drawn into the intake manifold. This causes increased oil usage, smoking, pinging and power loss. The additional oil usage will cause excessive carbon to build up on the oxygen sensor. The carbon acts as an insulator effecting the operation of the sensor which controls the power, mileage and emissions. We suggest you install a new pre-catalytic (front) O2 sensor when replacing the plenum cover and gasket.                                      We offer the NGK brand of O2 sensors. To be sure which sensors fit your vehicle please use NGK's website and then use the "Choose your Part" tool to find the correct part numbers. After finding your numbers, you can come back to our site and type the part numbers into our search tool to find the correct sensor and place your order.     Suggested Additional Items: HUG 1838   Coolant bypass pipe   HUG 3650   Dialectric Tune-Up Grease      HUG 1842    195º (OE Temp) Stainless Thermostat    HUG 22056   V8 Mag 1992-03 MSD/Accel/ NGK Tune Up Kit  ACL TST11    V8 Mag 1992-98 Accel Super Tune Up Kit         ACL TST24    V8 Mag 1999-02 Accel Super Tune Up Kit
