Product Description

The K&N 63-3083 is a 63 Series AirCharger cold air intake system engineered specifically for the 2013-2015 Cadillac ATS Sedan equipped with the naturally aspirated 2.5L inline-four engine in Standard and Luxury trims with rear-wheel drive. The system replaces the factory airbox and filter with an aerodynamically engineered roto-molded HDPE intake tube and an oversized conical cotton gauze filter, paired with a custom heat shield that mounts directly into the factory airbox space. The result is a guaranteed increase in horsepower and torque, with improved throttle response and a more pronounced induction note throughout the RPM range.

The intake tube is purpose-built to retain the factory MAF sensor and crankcase vent hose connections, and includes an adapter for the secondary air hose where equipped - ensuring full compatibility with the ATS's engine management system without requiring any modifications. Installation uses factory mounting points and can be completed in 90 minutes or less with standard hand tools. The included cotton gauze filter is pre-oiled, washable, and rated for up to 100,000 miles between services, making the 63-3083 a durable long-term upgrade backed by K&N's 10-Year/Million Mile Limited Warranty.
