- Guaranteed to increase horsepower- Designed to improve throttle response and engine sound- Low restriction aluminum tube- Easy to install, usually in 90 minutes or less- Lasts up to 160,000km before service is required (depending on driving conditions)- Replaces stock air intake system- Washable and reusable lifetime air filter- K&N Million Mile Limited WarrantyThe K&N 69-4521TS Air Intake fits some Chevrolet Cruze, Chevrolet Cruze Limited, Opel Astra J, and Vauxhall Astra MK6 models. The K&N 69-4521TS Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system. 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 69-4521TS air intake comes with a black rubber 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. The oversized cone shaped air filter can be used for up to 160,000km before servicing is needed depending on driving conditions.
