This high performance intercooler works to lower air charge temps, because cooler air is able to make more power, and also helps to lower the detonation threshold. This kit also has rerouted and upgraded intercooler piping, so airflow is smooth in flow and reaches the engine with less turbulence. Shrouding and all hardware is included for a great factory like fit and finish but with much improved performance.

• Intercooler with Mounting Brackets
• Intercooler Shroud, Under-panel & Seals (in Crinkle Coated Black)
• Mandrel Bent, Polished Intercooling Piping
• All Silicone Hoses
• Needed hardware
• "Active Autowerke" Licence Plate Frame
• Comprehensive Instructional install CD

Details from Active Autowerks
Factory intercoolers work well on factory 135 & 335i’s, but with added boost comes added heat load. To overcome this, Active Autowerke’s unit stands tall and way up front, catching more air with the help an 88% larger core and a specially designed shroud. All incoming air is channelled completely through the intercooler by the ram air scoops and no air can escape to the side. There is also an additional undercarriage sump tray to further block any unwanted air entering the engine bay area. This ensures that all in-coming air stream is routed directly through the intercooler first. The result is the maximun in air cooling that creates the greatest in latent heat transfer. Our tests show an air temp drop of close to 30° F in the intake manifold, with a gain of 12 usable rear wheel HP on a Mustang MD250 dynamometer. Btw: the ambient temperature in our shop measured a scorching 92°F during the session.

Note Before Ordering
BMW made a change to the E9x body style from 9/2009 making installation of the Active intercooler slightly different on certain models.
The easiest way to differentiate between the "facelift" model years is the style of the grills, headlights and general front appearance, or you can provide us your BMW VIN#.
