Good but not perfect
By SpaceManSpiff
I bought this manifold for my 2000 Mustang GT, because the original manifold was leaking coolant around the thermostat housing and it had started running into the spark plug wells, which of course was causing misfires. Overall, the Dorman manifold seems to be of pretty good quality, especially for the price. However, I have a couple of issues with it. First, the universal alternator bracket that comes with it does not fit well on a Mustang GT. There is a large plate that interferes with several of the hoses that stretch across the engine. Second, the holes for the screws that secure the coils over the spark plugs are plastic and are not threaded. The original manifold had threaded metal holes. The "installation instructions" were vague at best, so be sure to have another source to assist in the installation, like a Haynes manual.Now that I have the manifold installed and new spark plugs, the car is running fine and I have not seen any more leaking.

Great Quality, Great Price, and a performance increase to boot!
By Jeff
The stock plastic intake on my 2000 Mustang GT finally cracked right where the upper radiator hose attaches to the manifold. I needed an intake fast to get my car back on the road so I ordered the Dorman 615-175 manifold.I've read good and bad things about the Dorman VS the Ford replacement. Folks on several Mustang forums say the Dorman has smaller runners than the Ford & that the performance isn't as good. Well, I'm here to tell you the performance on a mostly stock 4.6 with the Dorman intake is noticeably BETTER than with the Ford intake!The slightly smaller runners actually increase the velocity of the incoming air which gives a very noticeable increase in performance in the low to mid RPM range with no noticeable ill effect at high RPM all the way to redline.On a car with performance camshafts & reworked heads the Dorman is probably not the best choice, but if you have the stock cams and heads you WILL feel a noticeable increase in torque. Way to go Dorman! :-)

4.6 INTAKE
By RSREAD
Best price as new. Too much time involded to risk using anything used. Took me about 6 hours taking old intake off, and another 6 to put it on. Did it outside in the cold.Goto [...] To know what you'er getting into. It's on a 97, mine was a 2001 police Crown Vic. A little different.Biggest problem was a backside brace on driver side, bolts in from firewall, bolts go in by firewall toward front, no way to get to. Cut brace in half; had to reuse it, one of the bolts (torque # 3,) holds the intake on. And the (torque # 7,) bolt is a B%#@% just guessed with a wrench on it's torque.Other than the cold, and guessing which alternator bracket to use, I only used one, directions doesn't state one or the other, or that you use only one of the 2 provided,)it fired right up, no leaks.Hint: take close photos of every item you unhook, can save ya a lot of guessing. I didn't take everything apart. the throttle body and the intake, used a bunggy cord and held it up out of the way. EGR just unbolted from the throttle body, wasn't really in the way. Fuel rails / injectors just bend over by the fender. Great time to change your plugs. Ready to go 100,000 more miles.GOOD LUCK!
