Spectre’s push‑in valve cover breather is designed for 1‑1/4 inch breather holes and features a 1 inch outside diameter neck, an internal baffle to help prevent oil splash, and a replaceable foam insert for maintenance. It’s compatible with optional grommet kits such as part number 5339, and the triple chrome‑plated steel construction offers both durability and a clean, finished look in the engine bay.
