Description

The Ireland Engineering HD Single Valve Springs are engineered as a performance upgrade for M10 engines, offering a robust solution for street performance applications. These springs are specifically recommended for engines running a 292 or 284 camshaft, providing a 45% increase in stiffness over stock OEM springs. They are sold as a complete set of 8 pieces, ensuring a comprehensive solution for valve train enhancement. It is crucial to note that for installation, late-style M10 valve guides and seals must be used, as older styles will interfere with the inner valve spring. The product is categorized under 2002 Valvetrain and E21 Valvetrain, with tags indicating Performance, Race, and Upgrade suitability.
