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

 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!

 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.

 Great Product, it WORKS and is very simple to install. I am always looking to get the best milage and performance out of my wifes Chevy Cruze LTZ/RS (4-cylinder Tubro). Purchased the car new so at 2,500 miles getting 26/27 miles per gal I ordered the K&N System the first tank of gas we got 31 miles per gal now at 7,800 mile we get an average of 29 in town and (42 HWY driving @75MPH). I have K&N systems on all my vechiles - 2002 Jeep Grand Cherokee 4.7 HO/ 2001 F250/V10/ 2001 custome Jeep Wrangler 6 clyinder. GREAT PRODUCT and Great service.

 Due to the popular demand of this product it took a while to be shipped. When it arrived the installation occured immediately. A month later I saw changes in my performance. This is a wonderful add on for your Cruze. Plus, people will think you have a blow off valve.

 This is my very first K&N cold air intake for any of my vehicles. I have bought K&N oil filters and panel filters in the past, but the intake systems really are where it's at for air flow. I bought this kit for my 2012 Chevrolet cruze ECO, and I can really notice a difference in performance, sound and quality. I'm very pleased with this product as I have been over the years with previous products. K&N makes excellent products. Hopefully someday soon they will make oil filters for the Cruze and Chevy Sonic as I will be buying those filters as well. I know my car is protected when I run with a K&N filter. Thank you all at K&N Engineering. God Bless
