The K&N 69-4526TS is a 69 Series Typhoon cold air intake for the 3.6L V6 in 2013 and 2014 Chevrolet Impala models, including the Impala Limited. It replaces the factory air filter and intake tube with a mandrel-bent aluminum tube and an oversized oiled cotton filter. The manufacturer estimates about 11.7 horsepower at 6218 RPM and roughly 8 lb-ft of torque from its dyno testing, so this is a measurable upgrade over stock rather than a cosmetic one. Compared with a cheaper universal cone filter, the kit is built as a complete, application-specific system, and its filter is designed to be washed and reused rather than replaced.

The manufacturer states the filter needs cleaning only about every 100,000 miles under normal highway driving. It also notes that dusty or off-road conditions call for more frequent cleaning.
The manufacturer's installation sheet states a typical installation can be completed in 60 minutes or less with simple hand tools.
This is a bolt-on job that the manufacturer rates at about an hour with basic hand tools, which makes it a realistic weekend project for a home mechanic. Follow the installation instruction sheet supplied with the kit and use all of the included hardware and clamps. K&N's instruction sheets for other Typhoon applications warn that skipping steps or substituting hardware can damage the intake tube, throttle body, or engine, so apply the same caution here. Clean or replace the filter on the manufacturer's schedule, and inspect the clamps and connections after your first few drives.
