The K&N 69-3539TB Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford Focus models. The restrictive factory air filter and air intake housing are replaced by the K&N Typhoon air intake which is designed to dramatically reduce air flow restriction as it smoothens and straightens air flow. This allows the engine to inhale a larger amount of air than the factory air intake. More air means more usable power and acceleration throughout the engine's RPM range. The 69-3539TB air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs using the factory mounting locations. A molded scoop funnels outside air towards the filter. The intake tube has an attractive blue powder-coat finish to match the car's badging and it accommodates the factory air pressure sensor. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. Installation can be done using common tools. Some Typhoon air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the vehicle applications and specific CARB stat.
