Get More TwinPower From Your 2011-2016 BMW 535i with a K&N AirCharger Air Intake
- Apr 27, 2017
To make V8-like power, the BMW N55 TwinPower engine uses a single turbocharger with two different sized scrolls. At low RPMs, the smaller scroll spools up to provide 300 lb-ft of torque at just 1200 RPM. As the revs increase, the second scroll kicks in to provide more boost. That BMW turbo uses the exhaust gas to spin a compressor that forces a large amount of air into the cylinders so the fuel detonation will be more intense. This additional oxygen allows the engine to extract more horsepower and torque from the fuel. But that air doesn't come from the turbo, it's piped in from outside the car through the stock air intake, then pressurized by the compressor. The problem here is, the air has to contend with a number of restrictions, including the thick paper OE BMW air filter, and the narrow factory intake tube. All of the dirt that builds up on the 'surface loading' air filter restricts the amount of air that can pass through. The air that does get past the filter, has to then travel to the engine through a narrow plastic tube that's full of uneven surfaces, which causes the air to swirl around and heat up. By increasing the air temperature, the oxygen content will be reduced, and the engine won't be able to create the maximum amount of power during the combustion cycle.
To verify these performance gains, a K&N 63-1132 AirCharger performance intake system was installed on a 2012 BMW 535i 3.0L, and dyno testing revealed an estimated increase of 13.53 horsepower and 13.44 lb-ft of torque. And don't forget, K&N makes an entire line of BMW 535i performance parts, which you can learn about by using the K&N search by vehicle tool. The K&N 63-1132 is designed to fit the following vehicles:
