In this video I clean up the Miata's engine bay a bit, both in washing and in swapping out the stock long tube intake in favor of a short ram intake using a 90 degree silicone elbow and a cone filter. Other Items you'll need are some 3/8 rubber tube from your local auto parts house and a 3/8 hose barb and union. I didn't link the cone filter because it's a little too big and there are better size options out there.

Leroy Engineering also has a great informative video about intake length and power differences. Check out this video about intake length.
