An easy way to free up some power in your 991.1 or 991.2 GT3. We recommend changing the airfilter when installing Dundon exhaust packages to reduce pumping losses and free up as much power as possible!
In conjunction with the Dundon Race Headers on the 991 GT3 the K&N air filters show about 8-9whp gain!
