Dorman615-188 Plastic Intake Manifold - Includes Gaskets Compatible with Select Ford Models (Made in USA)

Fit great works like it should. Have better engine response.

Worked good on my 2001 Ford f 250 5.4L only thing I could complain about is the self tapping screws instead of the OEM style

I am the original owner of a 2001 Expedition with 175,000 miles on it. I have performed 98% of all work done to this car. I replaced the manifold because of a coolant leak onto the engine from the passenger side coolant crossover section. Once it was off and upside down I could see a bulge in the plastic between the crossover and manifold. It leaked into cylinder 1 coil/sparkplug hole and shorted it out and into cylinder #1 intake valve. The sparkplug from that cylinder was burnt a brown color. I assume that was from the antifreeze leaking into and burning in that cylinder. I pulled codes for cylinder 1 misfire and both banks running lean. I installed the manifold in 13 hours total over 3 evenings after work. 4 of those hours were disassembling the throttle body and submerging it in lacquer thinner to clean all of the carbon from the ports and reassembling it. 2 hours were cleaning the fuel rail and injectors of residue. I wanted it as good as I could get it. You can do the job in 7 hours if you just want to get done. The manifold itself is nice quality. The coils, fuel rail and some other brackets use self tapping bolts that tap into the plastic manifold. The original uses brass sleeves to hold the bolts. They feel very solid so I don't think this will be a problem. That is the only negative I could find. The gaskets are included and permanently attached saving money and making it considerably easier to install. It comes with a new thermostat and seal. It comes with a new coolant crossover installed. Normally all of these things are bought individually. I have had it on for about a hundred miles. It seems to have more power than new. The lower plenum is smaller then the original and does not have a divider in the middle. I am guessing this allows for more direct airflow. It also appears the cylinder ports are arched at a better curve for airflow. I know it was 12 years and 175,00 miles ago but I think it runs better than new. I am extremely satisfied with the results. The price can't be beat. I rely heavily on this car for long distance trips. So far this is a fantastic improvement and purchase. If anything changes I will post it here.1/10/2014 It has now been 600 miles since install. I could not be happier so far. I had codes for cyl. 1 misfire and left bank running lean and right bank running lean. It cured all of them. I did replace the spark plugs and cyl. 1 coil because it had antifreeze shorting it out.04/26/2014 6000 miles now and no problems

I’ve had fairly good results from Dorman products in the past. A positive is it’s made in the USA. However, the self tapping screw application is questionable. Take your time, pre tap the holes prior to installation with the included screws and torque to specifications. Time will only tell its durability.

I installed this on my 2002 Ford F150 5.4 V8. So far it's still working with no issues after almost a year.

Works like it should. Bit of a different design than the original though.

Not OEM, not the right manifold for ford trition 5.4. Original has sensor for egr valve attached to plenum. I tried installing and bypassing but without deleting egr completely this entire manifold is useless. I am now doing job again with felpro gaskets on the original intake. 😄

Still doing a fine job. Easy install even if you’re a shade tree mechanic such as I.
