IAG Stage 2 CNC Ported EJ25 11mm Oil Pump for 04-21 STI 02-14 WRX 05-12 LGT 04-13 FXT

The IAG Stage 2 CNC Ported EJ25 11mm Oil Pump enhances the reliability and performance of Subaru EJ series engines. It starts as a new OEM Subaru 11mm oil pump, then is disassembled, ultrasonically cleaned, and modified. The OEM Pressure Relief Valve Piston is REM polished to reduce friction and prevent sticking. Rotors are precisely measured and "blueprinted" to meet or exceed manufacturer specifications, ensuring consistent oil pressure and delivery. Each pump is assembled with a light coating of assembly lube for priming during initial startup. The backing plate is securely installed with Loctite and correctly torqued hardware. This pump is vital for optimal lubrication in stock and mildly built EJ engines. The package includes one IAG 11mm Blueprinted Oil Pump, one front crankshaft seal, one oil pump O-ring, and seven zinc-plated bolts.
