Product Description

This listing includes a professionally modified set of +30% performance common rail diesel injectors for pre-DPF 4JJ1 engines. Built using genuine injector bodies and genuine nozzles, these injectors are engineered to deliver increased fuel flow while maintaining factory-level spray quality, reliability, and compatibility with the OEM fuel system.
Designed for modified engines, these injectors address the common limitation of factory injectors when boost and fuel demand are increased. Each set is professionally tested, flow matched, and electronically coded to ensure consistent performance across all cylinders.
Ideal for performance builds experiencing fuel starvation at higher power levels, helping improve overall engine output without compromising drivability or durability.

Important: At checkout, please specify whether you require early (5F) codes or facelift model (72) codes.
