A K&N AirCharger is the ultimate K&N performance upgrade for the 2011-2016 BMW 535i

Even though BMW started making cars back in 1928, they didn't actually become relevant until the 1980s. Thanks in part to a booming stock market and the invention of parachute pants, the BMW 5-Series became popular with customers who were cross-shopping midsize luxury cruisers like the Mercedes-Benz E-Class, Volvo 740, and Cadillac Seville (yep, you read that right). Fast forward to the 6th generation F10 2011-2016 BMW 535i, and this midsize luxury sedan had become the benchmark car in its class. Part of this dominance came from the stellar BMW N55 3.0L TwinPower straight-6, which used a new twin-scroll turbo and lots of other clever technology to produce a thrilling 300-hp. The innovative F07 2011-2016 BMW 535i Gran Turismo also used this motor, along with some very creative engineering to provide class-leading passenger and cargo room. But no matter which version of the F10 BMW 535i or F07 BMW 535i GT you have, a K&N 63-1132 AirCharger performance cold air intake system can help you see an estimated increase of over 13 horsepower.

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 reduce these airflow restrictions, the K&N 63-1132 AirCharger intake system replaces the air box and paper air filter with a large, low restriction K&N performance air filter, surrounded by a heat shield that seals itself against the underside of the hood to create a cold air chamber that's protected from the hot engine bay air. The high-flow cotton gauze material is able to send a lot more air to the turbo's compressor, and the 'depth loading' design allows it to remove far more contaminants from the air than a paper filter. That dirt will then stay trapped inside the 4–6 layers of oiled cotton gauze for up to 100,000 miles before it has to be cleaned (depending on road conditions). Once the dirt has been removed, the air then travels to the compressor through a low restriction polyethylene intake tube that has smooth interior surfaces to reduce air turbulence. All of this results in a high volume of cold air reaching the motor, which will allow it to extract more horsepower and torque during the combustion cycle. It also sharpens the throttle response, and you won't have to make any under-hood modifications or ECU programming changes.

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.
