The Injen Evolution intake for the F22 228i, F30 328i, and F32 428i has a lot of impressive features - 
  • Complete intake design, including the intake chargepipe,
  • Straightforward install, 
  • OEM-like appearance (not flashy), 
  • Roto-molded Polyethylene materials, 
  • Proven actual horsepower gains, 
  • Extra large filter surface area, 
  • Made in the USA
Although fresh to the BMW intake market, Injen is one of the most experienced and innovative intake manufacturers anywhere. Injen uses insulated Roto-molded Polyethylene (heavy duty plastic) for the airboxes and tubing. Not only does this give an OEM appearance but the plastic does not attract heat or raise underhood temperatures like a metal intake. Roto-molding also allowed Injen to manufacture an intake using CAD and 3D software so that all components fit perfectly in the engine bay.

Not only were we impressed with the quality and fitment of this intake but it actually made power: +15hp / +16ft-lbs of torque on the BimmerWorld dyno. Injen engineers design their intakes to carefully manage air velocity and air pressure using the Venturi Effect and velocity stacks. They also used the largest filter they could fit in the stock locations. With greater surface area and better flow there is more air available to make more power. The Injen Evolution intake fits with our belief that solid engineering and testing produces the best performance rather than flashy materials and marketing.
