How to make a DIY cold air intake for a miata

[Cardriverx]

Its acually fairly easy. I used 2.5inch shop-vac hose, but any other hose would work. Then I cut the stock plastic pipe that came out of the airbox right after the 90 degree bend. I attatched the vac hose to it. Then I drilled a hole in the firewall, stuck the vac hose in it, and silicone sealed it. Works good, noticed alittle more power, and a cool sound. These are some older pics, I cleaned the engine bay and shortened the hose alittle.
