The K&N 63-3121 air intake system replaces the restrictive factory air filter and air intake housing on specific Cadillac CT5-V Blackwing. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine's throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. 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 your vehicle's existing factory mounting points.

For over 50 years, K&N® has been an industry-leader in automotive filtration and technology—offering products to increase performance, protection, and longevity in thousands of vehicle applications for consumers worldwide. In the early 1960s, two motorcycle racers, Ken Johnson, and Norm McDonald (K&N), developed a ground-breaking new idea for an air filter—one that could perform under the demands of dusty, dirty off-road environments. After experimenting with numerous types of filter media, they discovered that an oiled cotton design allowed the filter to not only capture contaminants very efficiently, but also allowed it to be washed and reused, and the original K&N® High-Flow Air Filter™ was born. Five decades later, K&N® is still innovating industry-leading filtration technology and offers outstanding protection for everything from top-fuel dragsters to commuter vehicles across the globe. In addition to performance air filters, K&N® now manufactures a variety of other protection and performance products, including air intake systems, oil filters, fuel filters, cabin air filters, and home air filters, with a reputation for exceptional quality and customer service that millions of customers’ trust.
