When the phrase "bang for the buck” is thrown around, it's difficult not to think of the Ford Racing Performance Parts Three-Valve intake manifold. It is the least expensive manifold in our test, and the only one not constructed from cast aluminum.
"The Ford Racing Three-Valve intake manifold is constructed from composite plastic,” explains Jesse Kershaw of Ford Racing. "The composite offers a heat and weight advantage over aluminum intakes. When underhood temperatures go up, an aluminum intake will become heatsoaked and you lose horsepower and torque. The composite material used in the Ford Racing intake will not be affected the same way an aluminum intake would, so horsepower and torque are much more repeatable. The composite intake also weighs half compared to an aluminum intake.
"The Ford Racing intake gives you more plenum volume with shorter intake runners,” Kershaw adds. "The stock intake has about a 14-inch runner and the new intake's runners are 9.5 inches.”
A common misconception with composite intakes is its ability to stand up to boost. According to Kershaw, Ford Racing tested the new Three-Valve intake to 2.5-bar pressure or 35 psi, and after some ballooning in the early development phases, the intake manifold has specific reinforced areas, which allow for extremely high boost levels. This manifold would not be your best choice with high-boost or in applications where a lot of nitrous is being used. The chances of a composite intake surviving a nitrous backfire are slim.
Installation of the FRPP intake was a straightforward and easy. Everything needed to complete the installation, including a new fuel crossover hose, is included. On the dyno, heatsoak wasn't an issue. So once the engine was at temp, we began making pulls. The end result was 375 rwhp and 318 lb-ft of torque, netting FRPP a peak gain of 8 rwhp and 11 lb-ft of torque. Down low, the FRPP intake has small torque gains (2-3 lb-ft) until about 3,500 rpm, with little to no gain in horsepower. The effects of the shorter runners become apparent at about 4,100 rpm, and power and torque gains begin to slowly emerge, reaching its peak gain of 14 rwhp and 12 lb-ft at 6,000 rpm then tapering off slightly.
