BOUGHT THIS BRAND NEW FOR MY 03 COBRA. I NEVER INSTALLED IT BECAUSE I SOLD MY CAR. THE FOLLOWING INFO IS FOR PRO-M MASS AIR METER APPLICATION. The 85mm Flanged is a direct replacement for the 80mm OEM meter found in 96-2004 Mustangs and 97-03 Ford trucks. The 95mm Flanged is a direct replacement for 03-04 Cobra Mustangs, 01-03 Lightning trucks, and Harley Davidson trucks. The 95mm can also be used in the 85mm applications. The 85mm and 95mm flanged meters are made of billet aluminum, and feature welded construction (no cheesy rivets!). These meters will not become a corroded eye sore like the competition's products. They are clear anodized for good looks for many years to come. Retail Price 95mm - $379 $150shipped
