Restore Peak Electrical Performance with the 25230-C9965 Pro-Series Relay
If your Nissan or Infiniti is struggling with sudden stalling at intersections or an A/C system that only blows warm air, a compromised EGI or Fuel Pump Relay is often the hidden culprit. Over decades of use, internal contacts in factory relays can develop carbon buildup, leading to intermittent connection failures that are difficult to diagnose.
Our 25230-C9965 12V 30A Relay is built to restore your vehicle's factory reliability. We utilize high-grade silver-tin oxide contacts to ensure a crisp, consistent "click" and superior heat resistance. Unlike lower-quality alternatives, this relay includes a built-in suppression resistor, which is critical for protecting your car's expensive Engine Control Unit (ECU) during high-amperage switching.
Why This 2-Pack is Essential for Maintenance:
Targeted Problem Solving: Directly addresses the root cause of P0230 trouble codes and non-responsive fuel pumps.

Engineered for Longevity: Rated for 30A peak loads, it easily handles the high-current demands of cooling fans and fuel delivery systems without sticking or overheating.

Classic Fitment: Specifically designed with pin tolerances that match the original Nissan green relay blocks, ensuring a tight, vibration-proof connection even in 30-year-old fuse boxes.

Professional Installation Guide:
Locate the relay box under the hood (usually labeled on the underside of the lid).

Identify the green relay assigned to the Fuel Pump, EGI, or Ignition system.

Remove the old relay by pulling it straight up.

Align the 4 pins of your new 25230-C9965 and press firmly until seated.

Start the vehicle and verify the system is operational—you've just saved a trip to the dealership!

Note: Please verify your original relay part number matches 25230-C9965 or 25230-01Y00 before purchase. This 4-pin SPST relay is a normally open configuration.
