The link might not work, but if you take 2 seconds to type the website in it brings it right up. I built mine with 2 silicone boots, clamps, 4" exhaust pipe, a BHAF, and a heat sheild for less than $100. Air goes to the filter before intercooler, but the intake manifold is not the same as an intake. So you should figure out what your saying before running your mouth to people who make sense. Just my opinion.
