HUG 7714 V8 PLENUM REINFORCEMENT KIT FITS ALL 1993-2003 V8 MAGNUM ENGINES $86.00
 
Fits All 1993-2003 V8 Magnum Engines
Attention Magnum Truck Owners!
Tired of the gasket blowing out on your plenum cover? Engine pinging under acceleration? Using an excessive amount of oil? Notice 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, Grade 8 fasteners, new plenum gasket and detailed instructions. No factory fasteners are reused. We recommend replacing the intake bolts when you reinstall your intake. The bolts are TTY (torque-to-yield) and should not be reused. When purchasing the 7714 kit we suggest buying kit 3205B which includes all of the bolts and gaskets you will need to complete your project. This is also a very good time to replace your thermostat. We suggest using our 180º Hypertech thermostat # 1839 listed below in the related parts.
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. Below is an application chart to help you pick the correct sensor(s) for your applicaton. You can then choose the correct part number(s) from the related parts list below. Another way to be sure which sensors fit your vehicle you can use this link to NGK's website and then use the "Choose your Part" tool to find the correct part numbers.
CUSTOMER TESTIMONIALS:
"I just wanted to write and thank you for all you have done. I bought all the parts you recommended to repair/cure the oil usage issues on my truck. The Plenum repair kit was easy to install and the directions simple to follow. The good news is, not only does the truck run again on 87 octane, it actually runs better on 87 than it did before using 92 octane. I have not heard one valve tick, no pinging on acceleration, cruise control works like new, and, no oil usage over the last 1,000 miles. I am recommending your kit to everyone!
My only issue now is coming up with a new excuse for not letting my soon to be 17 year old son from getting the Dodge. it runs so well! You don't offer a kit for that issue do you?
Thanks again, D.P. Ohio"
"I just finished up installing the plenum reinforcement kit in my brothers 1996 Dodge Ram 1500 4x4 5.9 Magnum. I knew, from the symptoms it was presenting, that it was the plenum gasket, and through little research, came across Hughes Engines. I'm not a Dodge guy, so I never looked into them before my brothers truck started acting up. You could see that there had been a replacement plenum gasket installed at some point earlier in its life, probably a recall item or TSB, but it was gone in a couple of places. After the install, there seemed to be better power, and no longer did it ping under acceleration. You provide an excellent product, and the instructions would be easy for someone who doesn't know how to work on vehicles to understand. I should have taken pics of the new plenum pan installed, but all I have are pre-install, but here's a couple pics. Thanks again.Jim"
"I just wanted to let you know that I recently installed your plenum repair kit a few days ago. It was very well made and a perfect fit...I ordered my truck new and it has always consumed oil at the rate of a quart every 1000 miles...Since installing your kit, the oil level hasn't budged...I have utmost confidence in your product and will tell anyone who listens what a difference it made. I thank you for providing a workable repair that is far superior to a factory repair, at a price that is reasonable." R.P.
"Just wanted to say thanks for that Plenum kit. It did the trick. My factory plenum gasket was leaking in two different locations. I installed your kit per instructions and I am noticing that I stopped "using" oil and also my check engine light went out. Also the engine rattle is gone. As added measure, while the intake was off, I installed new high quality wires, cap and rotor. Put in the 180 degree stat as you recommend. Thanks again." L.N. Bumpass, VA
"Just installed the Magnum intake plenum cover, wow, it fits great and looks great, too bad you can't see it once it's installed, and best of all, no more smoke and no more spark knock, a much better piece than the mother Mopar stamped sheet metal cover!!! Thanks for your effort to improve my Mopars!!!" T. H. Elkton, VA
"Just wanted to let you know that I am very pleased with the plenum kit. It has been a week since I installed it and my 5.9L Magnum hasn't ran this good for a long time. I also took your advice and installed a 180 t-stat. The plenum plate that I bought from you is a much better design than the factory original. Thank you." R.B.
"I just installed your plenum repair kit p/n 7714, modified O.E.M. throttle body p/n 5500, a 180° thermostat and modified my TPS per your instructions (which were very well written). My plenum cover was blown out in two spots and on the way to a third. I actually have more power through third gear and when passing now. I must say the biggest improvements are after driving 750 miles , my 5.2 has consumed no oil, I'm running 89 octane (instead of 94) with no knock, and picked up 3 miles per gallon so far. THANK YOU for making a far superior product than Dodge did. The amazing thing is your prices are so reasonable for a aftermarket that offers so little for the Magnum motors. You could have easily charged double to triple the price. I will not hesitate to recommend your products to other Mopar lovers." D.W. Canadaigua, NY
