Complete 4-Injector Set for Perkins 1004 & 1006 Series Engines — Restore Full Power & Efficiency

The Perkins 1004 and 1006 engine family has powered decades of construction, agricultural, and industrial equipment — from JCB backhoes and Massey Ferguson tractors to generators and compressors. These engines are built to last, but injector wear is inevitable at high hours. When combustion becomes uneven, you lose power, burn more fuel, and risk costly downstream damage. This complete 4-piece set replaces every injector at once, restoring factory-spec performance across all cylinders.

Why This Set

• Perkins-Spec Engineering — Matched to OEM injection timing, spray geometry, and pressure parameters for the 1004-40T, 1004, 1006-60T, and 1006 engine variants
• Complete 4-Cylinder Coverage — All injectors replaced simultaneously for balanced combustion, consistent power delivery, and uniform fuel economy across every cylinder
• Eliminates Uneven Wear — Replacing the full set removes the performance gap between new and worn injectors that causes rough running and power loss
• Industrial & Mobile Equipment Rated — Built to endure continuous high-pressure cycling across the demanding duty cycles of construction, agricultural, and power generation use
• 100% New — Not Remanufactured — Full service life from installation; no worn nozzles, no compromised seals, no uncertainty at $408
• Direct OEM Replacement — Drop-in fit for listed Perkins engine variants; no modifications or adapters required

Pro tip: The Perkins 1004/1006 series is renowned for longevity — many engines run well past 10,000 hours with proper maintenance. At high mileage, replacing all 4 injectors during a scheduled service prevents the staggered failures that cause unplanned downtime and far exceed the cost of this set.
