This intake is amazing! It is 3AM here and I finally got it finished. It sounds great, and there is a clearly noticeable gain in horse power and torque. On main roads you get tons of power on the lower gears. Then, I decided to take it on the freeway. With the 4runner at higher speeds it takes awhile for it to get to lets say 80-90 or 90-100(Not that I ever tried :) ) But you get great response even at the higher speeds! I am very satisfied with this product and I recommend it to everyone with a Yota 4Runner! Thanks Jason for everything. I will be a lifetime customer of yours!
