Review on 🔧 A-Premium Upper Intake Manifold with Thermostat for Ford Crown Victoria Mustang Thunderbird Town Car Mercury Grand Marquis Cougar 1996-2000 V8 4.6L: High Quality and Compatibility by Ayush Bonuccelli

BUY WITH CARE. Initially, customer service was very fast and responsive. The product was nicely packaged. The part looked almost like it came from the factory. The biggest difference is the lack of brass grommets to attach accessories to. They supplied sheet metal screws to screw into the plastic that weren't as reliable as the factory screws. Be very careful when dressing. The fuel injection orifices were of different sizes. I've made several trips to the Copper State to source large o-rings to properly seal the fuel ports on the discharge valve side. Also pay attention. That after that either the pressure in the fuel pump or the fuel rail blew off the tips of the injectors. After the first time he ripped off 2 mounting holes so he wouldn't hold the rail properly. Tried to tap and insert a new thread, the result is the same. I ended up removing the brass bushings from the old chamber and gluing them onto the new chamber. Has been running for 2 weeks now with no problems. Founded in Plenary. There was a constant horrible vacuum leak. After removing the chamber several times and checking the seals and chamber for cracks or misalignment of the halves. I put a straight edge on the air intake guides. It was found that the plenum was not square or true. Didn't have time to wait another week or two for a replacement. I've already started forcing you to make the above changes and mods to get the Plenum working. In the end I put the camera on the sanding plane and leveled the 2 sides. I used high temperature silicone for the installation. I'm a retired mechanic, luckily I know how to do it and have the ability to make some adjustments. I consider this repair a "junkyard repair", I'd rather fix a crack in the old one or go to a landfill. These are disposable pressure chambers, so I ordered a new one. DO NOT DISCARD METAL BUSHINGS. YOU MAY NEED THEM. TIGHTEN LIGHTLY AT A TIME BECAUSE THE CAMERA BENDS A LOT. Plastic is not as thick and hard as factory After modifications and reengineering. The plenum has been orderly for the last 2 weeks.
