Breather Element 1/2in

The Breather Element 1/2in by Allstar Performance is an essential crankcase ventilation component designed to manage engine blow-by gases while protecting your engine from atmospheric contamination. Whether you're running a street engine, mild performance build, or track-focused application, a quality breather element prevents oil mist and moisture from accumulating in your crankcase, which directly extends engine longevity and maintains peak efficiency. This 1/2-inch port size fits the majority of aftermarket breather systems and catch cans used in custom engine builds.

Allstar's breather element uses a proven filtration media design that captures oil vapor and particulates while allowing high-volume airflow—critical in boosted or high-RPM applications where crankcase pressure spikes dramatically. The compact 4.1 x 2.05 x 7.05-inch form factor integrates seamlessly into custom intake plumbing without requiring significant engine bay rework. Its minimal 0.17 lb weight ensures zero impact on weight distribution or engine balance, and the element's durable construction handles thermal cycling in modern fuel-injected and carbureted engines alike.

Mechanics and enthusiasts building LS engines, small-block Chevys, Fords, and import platforms rely on this breather element to eliminate oil sludge before it recirculates into bearings or fouls PCV valves. It's equally effective in naturally aspirated or forced-induction setups, and works with both stock and modified valve cover configurations. Installation requires only basic hose routing to your existing crankcase breather port—no special tools or fabrication needed. For anyone serious about engine durability and cleanliness, this Allstar breather element is a low-cost insurance policy.
