Hey Guys, Im fairly new to diesels and looking to do a few upgrades for my 7.3. So far the only thing ive done is cut the muffler off at the cab. My state has no emission requirements. Now ive been looking at Cold air intakes and im wondering if anyone has a Speed By Spectre air intake or a Air Raid CAI? So far things about my truck: Automatic F350 CC SB 4x4 it has 256,500 Miles. Few other things im looking at is a set of gauges and maybe a tuner/chip for the truck. Not looking for any major gains just a little more hp and hopefully better fuel economy. Right now it gets about 17.5 if im not on the pedal. All comments welcomed.
