Increased Power* for 2015-2019 Hyundai Sonata & Kia Optima 2.4L Models

The 69-5321TS cold air intake system

Help protect the engine of your Sonata or Optima and gain a guaranteed increase in horsepower and torque with the K&N® 69-5321TS air intake system, engineered specifically for 2015-2019 Hyundai Sonata and Kia Optima 2.4L models. The K&N® 69-5321TS mandrel-bent aluminum intake system offers an estimated power increase of 5.8-horsepower and 8.4 lb./ft. of torque*.

WHY A K&N PERFORMANCE AIR INTAKE SYSTEM? BOOST HORSEPOWER AND TORQUE!

The 69-5321TS is designed to help provide a smooth, low-restriction path for airflow to the engine. Your engine needs oxygen to create power; the cylinders in your vehicle’s engine need to have air to create the explosion that produces horsepower and torque. Allowing a higher volume of air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power.

“Really helped the throttle delay in my 2018 Toyota Camry SE 2.5l 4cyl. Couldn't be happier.” – Lonnie from South Carolina [Part No. 69-8921TTK]

CAD-DESIGNED INTAKE TUBE INCREASES AIRFLOW

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. The 69-5321TS intake system features a mandrel-bent aluminum intake tube.

“Couldn’t be happier with this intake. Easy installation, great sound and noticeable performance. Looks great, sounds great and performs as advertised. Well done K&N.” – Shawn from North Carolina [Part No. 69-5321TS]

HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTION

Under normal circumstances, most automotive air filters demonstrate an inverse relationship between airflow and efficiency—the higher the airflow, the less efficient the air filter is at protecting the engine, and vice versa. The oiled design of K&N air filters assists in “absorbing” dirt particles—and in turn helps incorporate those particles into the filter surface itself, which helps maintain the filter’s efficiency and ability to flow air. When tiny particles are captured and saturated with oil, they in turn can become tacky, allowing them to capture other particles.

The High-Flow Air Filter™ included in the 69-5321TS intake kit is oversized with a conical shape, providing a greater surface area and allowing for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). High-Flow Air Filters feature an oiled, layered design—providing up to 50% more airflow than a traditional paper filter. When your filter does need to be cleaned, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each K&N intake (and filter!) is designed to last for the life of your vehicle.

“Easy installation, setup the rubber edging ahead of time and the rest is less than an hour. Idle smoothed out immediately with a noticeable acceleration boost. Nice sound.” – Barry from Georgia [Part No. 69-2026TTK]

WARRANTY

Each intake system comes with a 10-Year/Million Mile Limited Warranty. Furthermore, using a K&N replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.
