Improved air flow but...
Installed CAI and within 5 miles of driving the CEL came on. Took car to BMW dealer for service. Trouble code indicated lean air/fuel mix. Removed the CAI and reset computer. CEL went away and has not returned after 75+ miles of driving. Good looking product and improved air flow but I don't want to potentially burn the valves on a car with only 6k miles. Will not use CAI and will return for refund.
Made my 2006 Hemi Durango run like a beast, not only a power add-on it also increased my MPGs... wish I would have installed this Air Intake as soon as I bought my truck 5 yrs ago...best $$ spent, a must have for any vehicle.. I even bought another Cold Air Intake for my 2015 Scatpak 392 Hemi Charger, and installes it with only 140 miles on it.. should be standard equiptment!!!
