The Ford Focus RS is a popular option for automotive enthusiasts and K&N can help add power

The AWD Ford Focus RS has been designed and built for the automotive performance enthusiast. And enthusiasts are constantly seeking ways to improve the performance of their cars. If it’s a 2016 or 2017 Ford Focus RS you own, a K&N 69-3539TB cold air intake can add over 33 horsepower at the wheels to your already powerful road beast.

Chassis dynamometer testing verified an estimated increase from 224.46 horsepower to 258.47 horsepower, as measured at the drive wheels, on the same Ford Focus RS on the same day, with the only change being the installation of a K&N 69-3539TB.

The Focus RS features a 2.3L DOHC turbocharged EcoBoost engine delivering an astonishing 350 horsepower stock that can launch it from 0-60 mph in 4.5 seconds, which is just a tick slower than the Ford GT 40 Mk II that won the 24 Hours of Le Mans.

The 2.3L EcoBoost is an all-aluminum four-cylinder engine, with DOHC and four valves per cylinder with Twin Independent Variable Cam Timing (Ti-VCT). Stroke is unusually long for a performance engine at 94 mm versus a bore of 87.6 mm. Intake air is compressed by a Honeywell twin-scroll fixed geometry turbocharger, with engine management by a Bosch MEDG17-I4. Full power comes on a relatively low 6000 rpm, with peak torque at 3200 rpm.

The Typhoon Air Intake Kit also accommodates the engine’s factory emissions control devices

The K&N Typhoon air intake kit can add more than 33 HP to 2016 and 2017 Ford Focus RS

All that power is put down to the ground through the RS-only 19” aluminum wheels via an All-Wheel-Drive System that intelligently distributes power as needed: front to rear and left to right. This unique driveline can route up to 70 percent engine power to the rear wheels, and of that, 100 percent to either side depending on the driving situation.

As is the case with virtually all turbocharged engines and virtually all direct injection engines, the more intake air you can feed into the system, the more power the engine will make. In the example of the Ford Focus RS, an additional mass of air fed into the turbocharger is supplementary to what it normally draws, so its output is increased proportionally to the increase in input.

With this increase of air entering the combustion chamber, the electronic engine management of the Focus RS increases the amount of fuel to maintain the proper ratio of combustion. With more air and more fuel, more power is made. And that’s the basics of the K&N 69-3539TB Typhoon air intake system.

The 69-3539TB Typhoon air intake system is designed to fit 2016 and 2017 Ford Focus RS models. The power increase is achieved by replacing the OEM factory air filter, intake tube, and air filter housing with a aerodynamically-verified K&N Typhoon mandrel-bent aluminum tube air intake system, which is designed to dramatically reduce air flow restriction as it smooths and straightens air flow.

The heat shield and filter are designed to be located in the original air box space

The intake pipe is aerodynamically-engineered for maximum flow and powdercoated blue

A molded scoop funnels cold outside air toward the filter. Air is then directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube is powder-coated in an attractive blue finish that matches the Focus RS badging and includes a fitting for the factory air pressure sensor.

Included in the 69-3539TB Typhoon air intake kit is a K&N high-flow RU-5163 air filter and a heat shield that installs in the original factory mounting location. Much of the horsepower gain can be attributed to the oversized conical air filter manufactured from multiple layers of oiled cotton filter media -- which offers less resistance than traditional paper filters. The multi-layered red cotton material also filters out microparticles that could damage your engine. Each filter design is verified through K&N’s in-house testing lab, which adheres to ISO 5011 standards, ensuring that your K&N filter provides high airflow without putting engine protection at risk.

The pleated K&N RU-5163 conical air filter provides additional surface area for increased airflow

The oversized RU-5163 cone shaped air filter can be used for up to 100,000 miles before servicing is needed, depending on driving conditions. The only maintenance required is a simple service you can do yourself. At intervals of around 100,000 miles (or more frequently depending upon your driving conditions) use the K&N 99-5000 Recharger Kit clean and refresh your Typhoon intake air filter, preparing it for another 100,000 miles of driving.

This Typhoon air intake is relatively easy to install, typically in 90 minutes of less using common hand tools. All tools required are listed in the clear, step-by-step photo-illustrated instructions specific to your Ford Focus RS that comes included in the shipping carton.

The K&N air filter you purchase is designed to last for the lifetime of your vehicle, which K&N guarantees with a 10-Year/Million Mile Limited Warranty.
