BMW M3 WeaponR Secret Weapon Intake

The BMW M3 is a high performance BMW M GmbH version of the popular BMW 3-Series compact automobile. M3 models have been derived from the E30, E36, E46 and E90/E92/E93 3-series. Common upgrades over the "standard" 3-Series automobiles include more powerful and responsive (yet at times smaller) engines, improved handling/suspension, more aggressive aerodynamics/body, and multiple interior/exterior accents with the "M"/Motorsport nomenclature.

The E46 M3, first introduced in October, 2000, appeared worldwide with the new 3.2 L S54B32 engine. At the time of the car's introduction, this engine had the highest specific output naturally aspirated engine ever made by BMW, producing 343 PS (338 hp/252 kW) and 370 N•m (273 lb•ft).

The first batch of E46 M3s delivered were Laguna Seca Blue. The available SMG Drivelogic (also known as SMG II) transmission, a Formula 1-style electrohydraulic manual gearbox with no clutch pedal and steering wheel-mounted paddle shifters, is also a highlight. The model also came with a new 6-speed transmission and red-line RPM of 8000, a first for any BMW. The engine also consisted of 6 independent throttle bodies and electronically driven throttles (without a cable).

In the US, the E46 finally comes with virtually the same engine output as the European version, unlike in the E36 where it was heavily detuned. Power is now at 333 bhp (248 kW; 338 PS), five down on the German model due to an extra catalytic converter in the downpipe.

The BMW M3 is a powerful car right off the dealer's showroom floor, but that is no secret.  Many people want more.  One of the easiest and relatively low cost upgrades is to install a Short Ram Intake.  A Cold Air Intake will give you more horsepower and torque.  One of the best Cold Air Intake Systems for your money is the Secret Weapon Intake made by WeaponR.

The Secret Weapon Intake Systems is a result of countless hours of testing and tuning of air intake velocity, Air mass and Airspeed for each vehicle application. The Result; an intake system that performs better than any Cold Air Intake, but with a Short Ram. It is possible by WeaponR secret Patent Pending Speed Velocity theory, by creating a higher airspeed in the intake path you increase air mass and airspeed, which greatly increase horsepower.

The Secret Weapon Intake Systems are carefully CNC mandrel bent out of 6061 Aluminum, and then Hand Tig Welded in sections to ensure a constant balance in airflow, regulation in airspeed, positive seal and proper fitment. Each Secret Weapon intake systems are carefully tuned, by matching the engines displacement, air intake capacity and airspeed to the intake systems tube size, length and secondary pathway tubing diameters to maximize the full potential of the Secret Weapon Cold Air Intake.
