GEN PERFORMANCE K-Series Upper Coolant Housing with Straight Elbow Filler Neck Hose

GEN PERFORMANCE K20Z3 / K24 K-Series Upper Coolant Housing with Straight Elbow Filler Neck Hose

Engineered for performance and reliability, the GEN PERFORMANCE Upper Coolant Housing Kit is the ideal upgrade for K-Series enthusiasts looking to improve cooling system efficiency and engine bay functionality. Designed specifically for K20Z3 and K24 platforms, this billet aluminum housing delivers improved fitment flexibility, enhanced durability, and a cleaner overall setup compared to the restrictive factory unit.

Constructed from high-quality billet aluminum, this coolant housing is built to withstand the demands of high-performance applications while maintaining long-term reliability. The precision-machined design ensures proper sealing and optimal coolant flow, helping maintain consistent engine temperatures under both daily driving and aggressive conditions.

One of the key advantages of this upgrade is its adjustable outlet design. Unlike the fixed OEM housing, the pivoting hose outlet allows for approximately 15 degrees of angle adjustment. This added flexibility makes routing the upper radiator hose significantly easier, especially in modified setups where intake piping and engine bay space can become restrictive.

The integrated straight elbow filler neck enhances cooling system functionality by allowing improved coolant filling and bleeding. By positioning the fill point higher in the system, trapped air can escape more efficiently, reducing the risk of overheating and ensuring a more consistent cooling performance.
