Description

The IAG Single Valve Spring & Titanium Retainer Set reduces valvetrain weight by up to 153.6g and increases spring pressure, which enables you to run increased boost and RPM over stock. The set works with all Subaru EJ20 and EJ25 engines and should not exceed 8000RPM for safe operation.

The IAG Single Valve Spring Set is used on the IAG Stage 1 - 3 Cylinder Head packages found in our 550-700 EJ25 longs blocks which are rated up to 700BHP. The spring set may be used for stock replacement or with Stage 1 and Stage 2 camshafts utilized in mild street and road race applications.

Each set includes 16 single valve springs manufactured from the highest quality round chrome silicone alloy steel valve spring wire to IAG’s specifications and 16 titanium retainers machined and manufactured at our Westminster, MD facility.
