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 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. The tools needed are a couple of screwdrivers, pliers, ratchet set and an Allen wrench. 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 K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

K&N 69-4521TS Air Intake Product Reviews

Friday, April 27, 2018 - Part 69-4521TS
I have a 2014 Chevy Cruze LTZ RS. The intake completely gave my car a better sound and now it makes a blow off sound. Worth the money. Every K&N intake I have owned has been well worth it.

Excellent product. Easy to install, looks great and adds an element of fun to the car. Also adds a noticeable increase in throttle response at lower RPMs.

Quality products that not only increase HP, but also MPG. The stock air box is basically a muffler for the intake, engine sounds much better with the air box removed and this typhoon kit installed.
