New subscriber here, i have an 03 quad cab 4x4 (awd), it has a 4.7 v8, i have installed a magnaflow 3 inch cat back exhaust, and i believe that i have on of the good "y" pipes that everyone says needs to be changed. I was wondering if anyone can strongly recomend a decent spacer, one that actually does more than change the sound. Any and all input is greatly apreciated. thanks

what kind of spacer? throttle body?

yeah sorry, i am looking for a throttle body spacer, and a cold air intake, i do have plans to find a supercharger for it but that it a year or two away yet. So yeah any info you can share would be great thanks

I don't know specifically about the 4.7 and spacers, but supposedly they don't do a thing on a 5.2... a cold air intake should help you with power definitely. Just make sure you don't get one that angles towards the ground like many true cold air intakes are. This is just because in the 4wd world, you want an air inlet to be as high as possible to stay dry and clean. Don't want to go any lower than stock.
