Product Description

The Cometic C15279-040 HP Cylinder Head Gasket is engineered specifically for Ford's 2.3L EcoBoost engine models from 2015-2019. It features a high-performance multi-layer steel construction with five layers and an 89.25 mm bore size. With a compressed thickness of 0.040 inches, this gasket is built to maintain reliable sealing in both stock and moderately boosted or high load conditions.

This gasket fits multiple models including the Mustang EcoBoost, Explorer, and Lincoln MKC, but explicitly excludes the 2016-2018 Focus RS due to differences in the head casting and gasket requirements. Symmetrical design means there's no "left" or "right" orientation, simplifying installation. Because this is an HP series part, expect best performance in applications where thermal and mechanical load are elevated, such as performance tuning or heavier usage scenarios. Fitment confirmed through 2019. 2020+ EcoBoost variants are unverified.
