R Theory NA Miata Aluminum Hood Vents (1990-1997)

Aluminum hood vents for the NA Miata, made by R Theory Motorsports. The vents are laid out around the NA hood's inner frame, so nearly all of the frame stays uncut and the hood keeps its stiffness. Venting lets hot air from the radiator escape from under the hood instead of building up there.

Choose the forward 3 panels or the full 5 panel set. R Theory's testing found the full 5 panel set evacuates more heat, because the two rear panels sit in a lower-pressure area of the hood.

Fits

• NA Miata, 1990-1997

In the box

• Hood vent panels (3 or 5)
• Rivets
• Cutting stencil

Good to know

• The hood is cut to fit the vents, using the supplied stencil.
• Ships flat in raw aluminum, ready for paint or powder coat; the fins are bent open before coating.
• Rubber edge trim is sold separately and only needed when the vents are mounted on the underside of the hood.
• Pick Satin Black Powder Coat and R Theory powder coats the set in a UV-stable satin black before it ships. It adds roughly 1 to 2 weeks to the lead time, and the fins still arrive flat and bend to their working angle without cracking the finish.

Import tariffs covered: the price includes the US import tariff, so there is nothing extra to pay on delivery.
