"2006 STS-V makes installation a bit more difficult. The airbox and Mass Air Flow sensor have to come out, to split the case to install. 30 minute job, but what a result! The supercharger is sucking more air and putting it to good use... squawking the tires off the line, and as the 6 speed auto shifts to 2nd gear... activated traction control! I didn't really believe the horsepower claims, but I'm a beliver now!" —James S from Franklin, TN bought a K&N Air Filters for a 2006 Cadillac STS, STS-V, Supercharged 4.4L V8.
