Description
The Manley upgraded valve spring and titanium retainer set is a great choice for Subaru EJ20 / EJ25 engines with upgraded camshafts that require valve springs for increased lift and higher RPM use. The set combines Manley’s upgraded 245 lbs./in valve spring set (Part# 22180-16) with their matching titanium retainers (Part# 23180-16). The retainers are manufactured from heat treated aerospace grade titanium, then CNC machined to exacting tolerances for an excellent fit.
