Review on 🔧 High-Quality Stainless Steel Exhaust Manifold Set for Wrangler Grand Cherokee 4.0L - ECCPP Automotive Replacement by John Naidu

So far so good. I did quite a bit of research before buying, and the general consensus is that expensive distributors break just as often as cheap ones. I did the entire exhaust with a Magnaflow cat pipe and a Dyno-Max muffler. I'll mention a few things to help you: First, get your best gasket and some copper spray. I installed this in a '98 Jeep TJ and installing the lower side bolts was a PIA royalty! What worked for me was wrapping some tape around the 3/8 swivel and having a good selection of extensions. The tape made the pivot stiff enough that it would still rotate but stay at the same angle that I needed. If I didn't run out of dollars I would buy a set of flex head ratchet wrenches. Also, when removing the intake manifold, be careful not to damage the part that attaches to the dowel pins. Spray the penetrant around this area and slowly peel it off. If necessary, carefully pry around the indicated dowels. I didn't and I clicked a chunk of my consumption. Luckily it was the bottom of the alignment hole so it was still resting on the dowel where it should have been. If you don't align it properly, it will idle and you will do it again. Tighten the bolts in the correct order as per the fig. I thought mine had failed because it idled about 3km when starting and the exhaust manifold was glowing red. Turns out I must have messed up the idle valve when I was cleaning it. I replaced it with a new Mopar IAC. Another $120 and it works great.
