Description
Perfect for PI Head Swap. This is the same exact production Intake Manifold used by Ford on the 2001 to 2004 4.6L SOHC 2V V8 GT Mustangs. It is less expensive and a great alternative to high dollar aftermarket performance intake manifolds when performing a PI head swap on your Stang.

Application. This Ford Racing Performance Improvement (PI) Intake Manifold is a direct fit on 1999-2004 4.6L GT Mustangs with PI head ports. It can also be used on 1996-1998 4.6L engines with PI heads, with additional parts and modifications required.

Technical Note. 1999 and 2000 GT Mustangs will require the use of an alternator bracket from a 2001-2004 GT. All Mustangs will require a new factory style manifold to head gasket and a thermostat gasket.

Fitment: 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

    My intake manifold cracked and was spraying water all over the engine bay. I purchased this product and failed to read the note saying I would need to buy a new alternator bracket for an 01 - 04 Mustang GT. This was a bit frustrating until I found out that the replacement factory manifold would cost me $765.00. After buying this product, intake gaskets, throttle body gaskets (upper and lower), alternator bracket and bolts I spent exactly $270.00 and saved myself over $500.00. I am very pleased with the cost and the performance. This product works very well with the BBK Cold Air Intake Kit. The engine responds very quick and feels as if came alive. Installation was easy but somewhat time consuming. I spent probably a total of three hours on tear down and installation. Torque your bolts at 18 - 20 ft lbs. No Leaks!!!!

    SWEETT!!!!

    i broke the nipple on the back of my old manifold. ford wanted $2100 to fix it.no way!!!!! so after getting the manifold and all the other parts, it was about $400.not bad!!! the Installation Instructions are a little off and left 1 or 2 things out. but i did it on my 2001 4.6 gt and it was e/z. the things that should be in the Instructions are...1 the hose running along the v of the block, get a 13mm Standard Locking Flex Ratcheting Combination Wrench. at Sears it was $17... the bolt is really in there ...2 the new water pump nipple. i had to put silicone around it. 3 when i put the alternator bracket back on the holes were off so i drilled a new 1 in the alternator bracket.works great... just take your on it

    Perfect fit!!

    Quality service and quick delivery from American Muscle, you guys are GREAT! Intake went on without a hitch, had to modify existing alt bracket (piece of cake) took about 1 1/2 hours. American Muscle is and will always be my Mustang parts headquarters.

    It was such a great feeling to receive a genuine Ford Motor (racing) Company 4.6L Performance Improvement (PI) Intake Manifold. This was the [exact] same product that official Ford car dealers were offering for hundreds $$ more. Thanks American Muscle for once again providing prompt and reliable products and service.

    Amazing American Muscle

    American muscle for the win AGAIN. Not only is the part MUCH cheaper than at my local shops, but I actually got it MUCH faster than my local shops could even order it in! I was promised 5-7 business days and it showed up in 4, all the way from PA to ALBERTA CANADA. As usual, im very pleased with AM

    Intake Manifold

    This manifold was exactly what I was looking for! The manifolds that are available in town are the Dorman brand and do not use the factory gaskets! This manifold has the aluminum cross over that does away with the distortion found in the plastic manifolds. Thanks American Muscle!

    Actually stock

    To clear up any confusion for 2003 owners this is straight up stock so all you need to do is get gaskets and o rings. I recommend cleaning the head where the gasket sits before replacing.

    simply the best

    I installed this in my 98 gt. What a huge improvement in performance and exhaust note got raspier. I would suggest an after market throttle body and cool air intake to really take advantage of this product. Install was pretty easy and the step by step guide thats on am.com was flawless. Side note the 98 gt has the correct nipple and rear heater hose.
