Add some ponies to your 1999-2004 Mustang 4.6L 2V with Trick Flow's Track Heat intake manifolds. Designed for hot street and track-ready 4.6L SOHC Mustangs, the Track Heat 4.6L 2V manifolds improve performance in the meat of the engine's powerband between 1,500 and 6,500 rpm with unported cylinder heads and 1,500 and 7,200 rpm with aftermarket or ported cylinder heads. The secret lies with the symmetrical high-velocity intake ports and 75mm throttle body inlet, which work together to substantially increase airflow and distribute it evenly to the cylinders. With these revolutionary intakes, you will be rewarded with big increases in performance over more expensive manifolds! Don't worry about hood clearance--the Track Heat intakes are direct bolt-on replacements for stock and will fit under any stock-height hood.
