Subaru Legacy Cylinder Head

The Subaru Legacy Cylinder Head is the sealed cover of the combustion chamber that directs air and fuel in and purges exhaust. This improves engine breathing and performance. The spark plugs, intake and exhaust valves, and coolant and oil passages are all housed in the Cylinder Head to maintain temperature and lubrication in modern overhead cam designs. The torque-to-yield head bolts are clamped to allow permanent stretching that delivers uniform clamping. This uniform pressure allows the gasket to do the job of preventing misfires and overheating. Further, the gasket also stops the mixing of oil and coolant. More importantly, the gasket ensures the patency of the attachment of the Cylinder Head. Though cast iron was once the choice of builders for its strength, nowadays, lighter aluminum Cylinder Head designs rule. This is because they are able to drop weight, shed heat faster, and let those Subaru powerplants run higher compression without knock. Both types are beefed up around ports so builders can enlarge passages for better flow without cutting into water jackets. This is a proven path to extra horsepower across the Legacy lineup. A damaged Cylinder Head with worn guides, weak springs, or cracks can burn valves, kill a cylinder, or leak fluids, but if this component is functioning properly, you can still feel the spirited character of every Legacy and appreciate the lasting nature of Subaru engineering.

Our website stands as the go-to online destination for OEM Subaru Legacy Cylinder Head. With complete lines of genuine Subaru Legacy Cylinder Head available at unbeatable market prices, we ensure top quality, reliability, and durability.
