The K&N 69-5321TS Air Intake fits some Hyundai Sonata, and Kia Optima models. See vehicle applications link for details.
The K&N 69-5321TS Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Kia Optima models. This air intake is designed to replace the restrictive factory air filter and air intake housing. The 69-5321TS is engineered to significantly reduce air flow restriction, smoothing and straightening air flow. This allows your engine to inhale a larger amount of air than the factory air intake for more acceleration throughout the engine’s RPM range. The heat shield included with the 69-5321TS installs right into the previous air box space, helping to keep air entering the intake away from the heat coming off the engine. The smooth intake tube funnels air directly into the engine’s throttle body for a guaranteed power gain. The intake tube accommodates the factory mass air sensor and crank case vent hose. Not only does this intake help improve performance but it also provides great looks, with a durable silver powder-coat finish on the tube. Depending on driving conditions, the black-topped K&N high-flow air filter that can be used for up to 100,000 miles before servicing is needed. The relatively simple installation uses existing factory mounting points and can normally be accomplished 90 minutes or less. The tools needed are common: a flat blade screwdriver, a ratchet set, and some pliers. 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.

Sunday, February 17, 2019 - Part 69-5321TS
Feels much more responsive, sounds a hell of alot better with this growl even with a small 2.4l 4 cylinder. I'm surprised it's able to changed so much. Must buy for any car and K&N is the only way to go.

This is a fantastic product and was easy to install DIY. It took me about 1 hour 45 minutes and the instructions were great. I love the sound I now get at WOT and the acceleration If you go easy on the acceleration you can keep the engine sound almost normal, this was helpful so I had time to tell my wife what I had installed. I highly recommend this amazing product

I was never one who believed in intake systems but I decided to buy this particular one for my 2016 Sonata 2.4 through the recommendation of a friend and I was surprised that the intake was very effective in doing what it is supposed to do. Installation was a little troublesome as there wasn’t much room in the engine bay but the directions were very well put together. As one who never believed in these intakes I’m glad that K&N proved me wrong. I’m very happy with my new intake system and I recommend this to anyone who wants to give their Sonata a little push as well as an improvement in fuel mileage.
