If you haven’t seen a Performance Design intake manifold, you are missing out. When this company first came onto the scene everyone in the industry wondered how they had come out of nowhere to be this good at what they do. It turns out their parent company is pretty bad ass in the composite intake manifold manufacturing process, so they kinda knew what was going on. Fast forward a few years and instead of just offering ultra sexy carbon fiber intakes with huge price tags, they have come around to building intakes with combinations of carbon and injection molding and the results are super impressive. Check out the video below from Richard where the PD XS intake is being tested at Brian Tooley Racing. You’ll dig it.
