Hey all, I've been reading about the ISR Mod on many different models of 'Yotas, and was wondering, has anyone found a way to do the ISR mod on the 4.7 Tundra? My dad has a 2000, that he uses for hay and hauling. My brother and I put a true dual exhaust on for fathers day last year. With that, my dad kinda got the bug for modifying the truck. He wants to do some sort of intake, but the cheaper the better. Any ideas?

 

Don't have any experience with this motor but like anything else, if you can increase the volumetric efficiency then you have done good; this means a little bigger usually, less curves/obsitcles than stock and more filter surface area. If the stock intake is decent, you won't get much. Use whatever will fit in there, home depot pretty much has everything you need for this project....
