HyperFlow Cold Air Intakes and Rampods are dyno and track proven products.
Features of the HyperFlow Cold Air Intakes (CAI)
1.Heavy wall CNC Mandrel bent aluminium tube
2. Our Air Flow meter body is CNC machined to provide perfect fit to the cold air intake tube – no weld in the airstream, and the clean transition necessary for laminar flow
3. Available in polished, powder coated Red or Black
4. The HyperFlow Air Filter has proven performance benefits with superior filtration

We have proven on the track and Dyno that our Cold Air Intakes do not cause lean out conditions to make increased power. (See our Technical Bulletin October 2006 for dyno results)
On our MY06 WRX STi, the cold Air Intake increased power by 15kw at the wheels (from 159.2 kw to 174.3 kw).
It should be noted the HyperFlow Cold Air Intake would increase induction noise with the free flowing Air Filter. We do provide an option on the Air Intake Filter to reduce noise, however this does affect the power output.
