K&N Typhoon Cold Air Intake system is a free-flowing, mandrel-bent induction kit that replaces your vehicles restrictive air box. Guaranteed to increase horsepower, improve throttle response and engine sound. Lasts up to 160,000km between services. Easy to install, usually in less than 90 minutes. The K&N 69-3517TS 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 smoothes and straightens air flow. This allows your 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 69-3517TS air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine's throttle body for a guaranteed power gain. The intake tube has an attractive silver powder-coated finish that's made to last and accommodates the factory mass air sensor, EVAP vent line and a replacement silicone crank case vent hose. The oversized cone shaped air filter can be used for up to 160,000km 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. The tools needed are a screwdriver, ratchet set and an Allen wrench.
