Oversteer Posted July 26, 2017 Posted July 26, 2017 (edited) 30% better flow than oem. Other uprated ones state 10% over oem. There was a noticeable difference when I put these in. Uprated air filters are the only modification required for a re-map with the HR engines (stage 1). Used for two weeks, approx 400 miles. For sale as I'm part-ex'ing my Z. As new condition. £45 delivered! Edited July 28, 2017 by Oversteer
