F/S Unique AFE filter , cleaned, lightly oiled. AFE is well know in BMW circles for quality and good flow. Their oil is said to be less of a factor to MAF contamination than other oils. I did not experience any CELs in 6 months of use. Did notice improved throttle response. Asking $40 shipped. Call 413-583-4229 or ollson4229@charter.net. Thanks, Jack
