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.

Product Reviews


  Easy install. Sounds great. I would recommend K & N anytime
RAYMOND SCHWEISSINGER WISCONSIN
  This intake does wonders. The difference in sound is night and day. I can hear my turbo spooling up and the blow-off sounds like it's in the glove box Definitely noticed a bit of increase in power past 5k too. 10/10, would recommend to anyone wanting a bit more out of their Chevy Cruze
Frank Espinoza IV United States
  I love the sound of my turbo Spooling up. Thanks K&N.
Horacio Vega Houston, Texas
  Small but noticeable difference, especially in torque at all speeds. The sound is different than I expected. Not so much louder but the engine makes a whooshing, hissing sound at all speeds. Not a muscley sound more like air rushing. Odd and distracting but this is my first car with a turbo ('14 Cruze with 1.4L) so maybe that's just the way it is. Still, did what it said it would- more boost than I expected.
Greg Fargo, North Dakota
  It was a noticeable improvement. Easy installation,
Brian Michigan
  Amazing!! Can feel the difference. Haven't had my stereo on since I installed it, just want to listen to that turbo spool and blow off! About all I can hear now is constant turbo :)
Max Whitworth Branson, Missouri
  Fitted this to my astra gtc and the sound difference is unbelievable. You can hear the turbo spool up and the blow off valve open and close. I have also seen an instant increase in mpg plus the engine is a bit more responsive and there is less lag from the turbo.
