Review on 🚀 K&N Cold Air Intake Kit: High Performance, Guaranteed Horsepower Increase for 2004-2006 SATURN (Ion) - Model 69-8431TP by Marco Cervantes

Excellent quality, contrary to popular belief these filters DO NOT affect the MAF sensor. [.]. I am a professional engineer and ALL my cars, ALL trucks and a few customer cars have K&N filters and NONE have ever had a problem with the filter oil. If the sensor ever failed, it was due to age burn. (which REALLY happens) This shot increased my MPG on our 2007 Redline Ion from 35 to 37 on the highway and increased its 12 wheel horsepower on our Mustang dyno. enough. He's been in the car 28,987 miles and never had a problem with anything. Be sure to use the included water jacket for the cone filter, and that's fine even in inclement weather.
