What do u all think if i install jet mass air flow, bbk 65mm throttle bodies and jet spacer, all ready have a after market K&N, IF I ONLY UPGRADE THE Y PIPE or should the truck be fine stock!
i know it's been posted on here before.... the only way you'll need ANY of those air flow devices is if you super charge / turbo charge! if you're really set on it, i'll sell you my throttle body spacer.
