Product Details
Like all cars, the best thing to start with is the intake and exhaust. So first on our product list for the Ford Focus ST was the intake system. Now the turbocharged Focus could always use some more air flow to increase power. The intake system is designed in a very direct manner from Ford. Airflow comes into the intake box from the front bumper small openings. It then travels past the sensor tube to behind the engine cover, and finally connects to a turbo inlet pipe directly to the turbocharger. Generally when designing a factory replacement intake kit, you want to retain the MAF or MAP sensor pipe diameter while improving airflow. For this we chose to keep the diameter of the intake pipe the same and continue its modularity with a separate turbo inlet pipe (sold separately), while reducing the restriction.

Utilizing a K&N cone air filter, we designed the air intake box to pull air from the factory inlet off the bumper but also via the open space that the engine has. With a heat shield and filter cover, the filter is able to provide the turbocharger with more air directly. Though some will argue the difference of "hot engine” air compared to a true cold air intake, test show using thermo couplers that the IAT's are a minimal difference outside to inside of the plastic factory intake. Dyno testing, the intake had very consistent torque and horsepower gains through the peak of the RPM band of 3700 to 6000. Averaging about 10hp and 10ft/lbs of torque, the intake made almost 13 wheel horsepower at 5300 rpm.
 

The intake kit is available in wrinkled black powdercoat standard. Optional colors are available for the intake pipe only. The box will remain wrinkled black.
