    Ask a Question

    This replacement intake has the pre installed gaskets right? Will I need to buy the gasket strip separately and place under the manifold? Or do I just clean it off and set the manifold directly on the metal? Will the pre installed gaskets prevent leaks or do I need a separate gasket strip?

    maurrio

    • Yes just set the new intake with the pre installed gaskets directly on the heads after cleaning first of course, the gaskets provided should comply with the oem specifications therefore they should give no problem

    Can any gasket set be used or does it have to be the individual ones like shown in the picture?

    • The OPR Replacement PI Intake Manifold will work with any intake manifold gaskets designed for the OEM intake manifold.

    Why wouldn't it fit a crown Vic it's the same engine 4.6 2v and the manifold looks just like this one.

    RaulF

    • Here at American Muscle we specialize in Aftermarket Mustang performance parts. While this may fit on some Crown Victoria years, we do not specialize in these and cannot confirm fitment as Ford made several changes, such as the PI head/intake staggered for different models, with the Mustang receiving the updated parts before the Crown Vic. All of our fitment listings are for Mustangs only, and it would be the purchaser's responsibility to confirm fitment on non Mustang applications.

      I give it 4 Stars

      I bought this I take because it was the only thing I could afford mine was shot. So far I like it only took about 1 he 45 mins with help so. O would recommend it because I don't have to miss with the gasket sliding around when you put intake on so thanks American muscle for a great product

      Not very impressed

      First off, please just do not buy this product. It looks nice in the picture, but they made this intake as cheap as possible and it shows. All the parts were not included in my kit (the plug for the open hole by the thermostat). I'm not impressed one bit with this product. I would have been much happier with just spending 80 more dollars on a better one.

      Just in time

      My passenger gasket went out so I bought a new manifold because I wasn’t sure if the old one was bad so to save money instead of buying one gasket I bought this and when the manifold came off it was warped so I did save money and didn’t have to worry for my drive up north for the holiday. Plus it looks better small visual difference.

      Perfect Christmas Gift

      Perfect fit!!!! if you are having problems with the thermostat housing leaks and all. This is a must have complete seal!!! perfect fit, no issues what so ever. Took me a while to install since you get the chance to get everything cleaned up for when its back on you don't have that dirty engine with a new intake manifold. Fitted on my Roush 2000 and gave it quite a tune-up.

      Very good Intake

      Tha OPR intake was pretty much straight forward, the installation was smooth and also notice okay gains, not like the Ford racing one but pretty close and with the cost can't go wrong. I'm happy with it.

      Budget fix

      This Intake manifold is good for a temporary fix and that’s about it. Almost all threads on this are plastic and aren’t reinforced with steel like the Ford Racing OEM Intake Manifold. I don’t know about you, but I didn’t like screwing my fuel rails into plastic threads.

      Decent Intake

      The intake itself is working properly. Not REAL happy with the self tappers for the coils and injectors, but it did work out. If your in a pinch and low budget this is your intake. If you have the extra money to spend I would recommend the Ford unit due to no self tappers. But overall it got me on the road and is working properly.
