This is a set of 16 Manley Valvesprings and Titanium Retainers for Honda Civic Si B16A, Integra GSR B18C, B-Series VTEC Engines.

Manley is known for their superior quality in manufacturing. These springs are wound from super clean chrome silicon high tensile strength steel alloy, and are heat treated and shot peened to ensure long service life in applications featuring high lift cams. These valvesprings are specifically designed to live in the extreme conditions of a race engine reving at high rpm with high lift cams.

Manley's lightweight titanium retainers decrease the amount of mass at the end of the spring, allowing you to rev higher while avoiding dangerous valve float conditions.
