Our new Typhoon intake system for the 4.6L Ford Mustang is a really sensational manifold. Developed in conjunction with one of the leading Mustang specialists, this manifold has been chassis dyno proven to produce 21.5 more rear wheel hp than a stock manifold at 6,500 rpm. More torque from 4,000 rpm on up. This manifold features a three piece design that allows easy access to the bottom and the middle of the plenum chamber along with the runners for those who want to do their own additional port and plenum fine tuning. The manifold is a bolt-in replacement for all 1999 to 2004 engines and uses the stock alternator and all other stock engine accessories. Can be used on 1996-'98 engines if 1999 or later heads are used. For additional 4.6L 2-V enhancements that will substantially improve the power and performance, see the various accessories shown below.

Special Note: On a stock engine, this manifold will substantially improve the mid-range power and torque. To realize the full advantage of this manifold, which makes its maximum power increase at approximately 6,300 rpm, a cam change is required. The stock cams will not allow the engine to rev this high. With a cam change, this manifold will produce in excess of 20 more rear wheel horsepower. This is over the power realized with a cam change and the stock manifold.
