  • Dyno Proven 21.5 RWHP Increase
  • For Street or Track
  • Easy Port & Plenum Fine Tuning
  • Uses Stock Engine Accessories
  • Fits 1999-2004 4.6L GT Mustangs
Dyno proven performance gains.   This satin finish Typhoon manifold has been chassis dyno proven to produce 21.5 more rear wheel horsepower than the stock factory manifold at 6,500 rpm and more torque from 4,000 rpm on up (with a cam upgrade).

Three Piece Design. Not only is the Typhoon intake manifold compatible with stock engine accessories (such as alternator, pullies, etc.), it's constructed as a three piece design to allow easy access to the bottom and middle of the plenum chamber and the runners for additional port and plenum fine tuning.

Uses stock engine accessories. The Typhoon manifold is a direct bolt-in replacement for all 1999 to 2004 4.6 2V engines and uses the stock alternator and other stock engine accessories.

Recommended Upgrade. To realize the full power potential that this intake manifold has to offer, a cam change is highly recommended. American Muscle recommends Comp Cams Stage III Xtreme Energy XE270AH Camshafts for the 1999-2004 4.6 2V Mustangs.

Application. This Typhoon Intake Manifold is designed for the 1999 to 2004 4.6L GT's and can also be used on 1996-1998 4.6 GT engines if 1999+ heads are used along with additional modifications and required parts.

Technical Notes: The stock intake manifold bolts are too short and the nine bolts supplied in this kit must be used. The two stock bolts that go through the thermostat area of the manifold can be used. The four bolts holding the upper plenum to the manifold are too long and you must use the supplied kit bolts.

How much power over stock will I gain with a tune? I want to know the HP and TQ difference over the stock intake without Stage 2 cams, but with a tune.

Silverpony01 Year: 2001 Model: GT

  • My car was tuned before and after the install and I gained 18 hp just with the install. I am not 100% on torque so I can't say on it but I'm sure it was similar.

    Great product

    Bought this plenum because the factory one cracked, and was causing coolant leaks at the thermostat housing. Painted mine black along with the throttle body. I did not have any clearance. late 01 models to 04 models have a change in design with the line coming from the back of the water pump, so the plenum bowl doesnt hit. Dont know if that was the problem for Irish, but that could be the reason. Also agree with Mitchell, you will feel a bigger difference if you port the runners. if you are worried about damaging the gaskets, you can go to advance or autozone, and buy a gasket sheet, and save a couple of bucks. I had to do this, and i searched to see if PP sold a gasket kit, but no luck, so i just made my own, and it works just fine, just a little time consuming. Overall great product for a good price, and no worry about cracking.

    I agree with Irish. I got mine powder coated blue along with my TB and the only issue was the water pump clearance. Otherwise, i could definitely tell the car wasn't gasping fo air above 4500rpms with no noticeable loss down low. Great for nitrous as well.

    Nice BUT!!

    The intake is nice and is better than the stock intake. The only problem was I had to file down the new intake in one spot because it did not clear the line coming out of the back of the water pump.

    Satin Manifold

    Good Intake but only RWHP you'll feel is if you port the runners itself. overall it wont crack like the factory manifold! thats a good sign!!

    Not Bad

    It's cast aluminum so there are some rough spots on the interior that could be cleaned up. The worst part was the manifold is in 3 pieces, and out of the box the bottom cover plate was not tight and leaked vacuum. Also, don't order the gaskets from AM, get some good Felpro gaskets. With stock cams and TB there wasn't much of a performance increase, maybe a bit at mid range but nothing to write home about. A good replacement for factory though if yours was cracked like mine.

    Professional products intake

    Great and easy intake! I ddid have the problem with clearing the water return line in the valley but i didnt file the intake. I took a socket and placed it on the hard line where it wouldnt clear (I only needed like an 1/16 of an inch)and hammered it a few stricks to dent that line just a hair and worked perfect! lot better than filing the intake in my opion

    super easy install!

    I was a little put out by the price at first. but I wasnt about to install another chincy O.E.M. intake. so I orded this one... I love it! the only cheaky part was the heater core feed pipe coming from the back of the water pump housing. it took a bit of tinkering but no matter. I had a mate powdercoat it flat gloss black. and no ones the wiser. shes sound as a pound and when you give it the beans she goes like a train! bottom line... BUY THIS INTAKE!

    dont buy

    had one of these intakes on my 02 GT because I blew the factory one with nitrous. If you are running nitrous go for it. If not dont. I took mine off and went back to a stock manifold and picked up 12 RWHP and almost 20 RWTQ. The runners were not ported but were cleaned up from the previous owner to get some of the roughness off them. the stock manifold flows better for the fact that it is plastic and doesnt have any of the rough texture from the metal casting.

    This manifold is poorly manufactured and pre-assembled, I was shocked at how rough the runners and plenum are. Ensure you torque down all the bolts on this manifold that are pre-installed (18 lb ft), all of mine were hand tight. Also be careful when installing the upper plenum (89 lb in) these bolts will strip out very easily. I strongly recommend Fel-Pro gaskets and Standard Motor Products SK57 injector seals if your vehicle has over 75,000 miles. I am ASE certified master technician and have been a mechanic for over fifteen years. I have never seen such a poorly manufactured product for the price. After the intake swap from stock to P.P. Typhoon intake, I have lost 17RWHP an 20 LB FT of torque. My mustang is stock for now, other than this manifold and willl barely bark the tires in first gear now.
