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

  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.
Jack Scotland
  I have a turbo and it was slow to get going. After this filter assembly made the turbo lag a lot better. Now when I pull out in traffic the lag in the turbo is almost gone. It makes driving a lot better. I would tell anyone that has a turbo to get this as soon as you can!!!
Albert Haines Florida
  This intake system did exactly what was advertised. It was extremely easy and quick to install and the performance increase was instantly noticed. With this intake you do hear the turbo kick in more, and the note of the engine changes slightly. But in all honesty if you are wanting to put this cold air intake on your Cruze, you probably want the additional sound. In addition to the K&N intake I have also installed a Jet Performance, Stage 1 ECU power module. These two components seem to compliment each other very nicely.

  I have had the 69-4521TS in for a week or two and I love it. I have a lot more low end torque and much smoother power curve. I would recommend this to anyone that has a Chevy Cruze. Much more fun to drive!
William Wear Boca Raton Florida
  I love my new intake! I've already noticed big gains in both performance and fuel economy in the little time I have had it installed! I mainly do city driving and I have already seen around a 2 mpg increase. I can't wait to see how much of a gain I am able to make on the highway. If there is one bad side it's that it makes the car a lot louder. You are really able to hear the turbo now which is cool but it is a lot louder than I expected. Even with that being the case I'm still in love with it!

  Great intake, easy install, and sounds really good.
