Ram Air Intake

The four valve per cylinder BMW engines can move a lot of CFM, therefore improving air intake flow translates into immediate power gains. Our air intake system includes a ram air tube, modified brake duct and the high flow K&N Filtercharger.

The key part is the air ram tube that picks up air from the pressurized left brake duct (without a loss in brake cooling), forcing it up through a new intake air tube and on through the more efficient K&N air filtercharger.

The advantage over cone filter intakes is that our Ram-Air system is always getting cool outside air, never losing power from ingesting hot under-hood air. The temperature difference can exceed 100° F in city driving or waiting in line for your autocross run. SAE correction factors for temperature give a horsepower loss of about 5% for a 50° F increase, 9% loss for a 100° F increase. In an M3, that's over 20 H.P!

The second advantage is that cone filter intakes rely on manifold vacuum to draw air through the filter. Our Ram-Air system gets positive pressure, the faster your road speed, the greater the ram-air effect. The air flow sensor automatically meters the correct fuel curve to match the increased air flow. There is no re-tuning, no change to emissions specs, just bolt on and go faster! All kits include K&N Filtercharger.

K & N Filtercharger

The K & N Filtercharger is unsurpassed in filtration protection, while maintaining an air flow greater that the OEM paper filter. Constructed of a pleated special cotton fabric with aluminum screen mesh and wide rubber seals, it comes pre-oiled with a one million mile warranty. When dirty, simply clean, re-oil and reinstall. These filters are a direct replacement for your factory paper element.

Schrick Performance Intake Manifold for BMW M52 2.8 & 3.2

On the M52 engines BMW uses one intake manifold design for engine capacities from 2.0 to 3.2 liters (U.S. Models 328 and 3.2 M3). These manifolds produce excellent torque but in the larger capacity engines they don't supply sufficient flow at higher rpm. This is especially noticeable on engines modified for increased power.

Schrick's goal was to design a manifold which would provide increased performance at higher rpm's without sacrificing low end torque. They accomplished this using 3D-CAD software to optimized flow at all rpm ranges. The new manifold design includes changes in the intake runner diameter, length and shape, the air plenum chamber has been enlarged for greater capacity, and the injectors have been moved closer to the ports.

Schrick dyno tests on the 2.8L engine showed a 14HP increase with no other modifications. A larger increase is expected in the 3.2 engines. Further gains are possible with the computer programming, performance cams, free flow exhausts, cylinder head modifications, etc.

The Schrick manifold is made with a removable plenum cover which allows access for porting and polishing for further air flow increases. The manifold is a direct bolt-on upgrade for the 2.8 and 3.2 liter engines. Installation Time: Approximately 3 hours. P/N 1161160017
