Intake Valley Covers

Intake Valley Covers are crucial internal engine components that play a significant role in the performance and longevity of your vehicle. Specifically designed to seal the valley area between cylinder heads on various engines, including LS platforms, these covers are essential for proper engine function. They often incorporate or facilitate features like the PCV valve function, which is vital for crankcase ventilation, preventing pressure buildup and oil contamination.

Many enthusiasts and mechanics also utilize specific types of intake valley covers, such as an LS valley cover or an AFM delete valley cover, when performing modifications like an AFM delete plate (Active Fuel Management) or a DOD delete plate (Displacement on Demand) to optimize engine performance and simplify the valvetrain. Beyond their functional importance, some intake valley covers also contribute to the aesthetic of your engine, offering an opportunity to enhance your engine bay dress-up kit. When searching for these parts online, you'll often find them referred to by their specific applications or features, reflecting their diverse utility in engine maintenance and modification.
