13B Rotary Intake Port Cover – 1/4” Acrylic

Product Description

This 13B rotary intake port cover is designed to protect open intake ports from debris, dust, and moisture during engine assembly, maintenance, storage, transport, and fabrication work. Laser cut from 1/4” thick acrylic, it provides a rigid, durable barrier to help prevent contamination or debris from entering the intake runners and engine internals while the engine is non-operational. Ideal for engines on stands or vehicles undergoing long-term projects, this cover is intended for non-operational use only.

Note: Product images shown feature the Smoked Grey acrylic finish. Multiple colors and finishes are available—please select your preferred option before checkout. Engine components and accessories shown in photos are not included with the cover.
