Suitable for Euro 4 YD25 engines with EGR cooler mounted at the front and 4-bolt EGR valve on intake. Not compatible with Euro 5 / 140kW engines (see related products).

EGR Cooler Delete / Bypass Kit for Nissan Navara D40 and Pathfinder R51 with YD25 2.5L Euro 4 diesel engines

Compatible with:

• Nissan Navara D40 – Spain-built (VIN starts with "VSK"), built up to 01/2010
• Nissan Navara D40 – Thailand-built (VIN starts with "MNT"), all build dates
• Nissan Pathfinder R51 – Spain-built (VIN starts with "VSK"), built up to 01/2010

These Euro 4 engines can be identified by the EGR cooler mounted at the front of the engine and an EGR valve secured to the intake manifold with four bolts.

This kit includes everything needed to remove and bypass the EGR cooler, along with detailed step-by-step installation instructions. Installation typically takes a few hours using basic mechanical tools.

The EGR system will be electronically disabled without triggering any fault codes or limp mode. The factory ECU will continue to operate normally with zero EGR flow.

Key Benefits:

• Eliminates the common EGR pipe cracking issue at the exhaust manifold
• Prevents overheating and engine/cylinder head failure from EGR cooler leaks
• Improves fuel efficiency and throttle response
• Reduces intake and coolant temperatures
• Extends engine oil life by reducing soot contamination

We also recommend a full intake manifold clean during installation to restore airflow and engine performance. These engines are known to suffer from heavy carbon buildup.

This kit is available with or without an optional intake derestriction plate for additional flow improvement.

Protect your engine and restore performance with this proven upgrade – especially important for towing, off-road use, or high-mileage vehicles.

Complete the modification with ECU tuning

The plate handles the physical blanking, while the required ECU calibration addresses EGR operation and monitoring. Installing a plate without suitable calibration can trigger EGR-related fault codes, an engine warning light or limp mode.

If your vehicle still needs this calibration, select the mail-in ECU tuning option above when ordering. This service requires you to send your engine ECU to us. Customers who already have suitable EGR calibration can purchase the plate on its own.

For installation and tuning at our Sunshine Coast workshop, submit an online tuning enquiry with your vehicle details.

Intake cleaning alongside the installation

Blanking the EGR passage does not remove soot and carbon already deposited in the intake manifold. Where deposits are restricting airflow, cleaning the intake can address that existing buildup.

Euro Car Electronics offers intake manifold cleaning, with ultrasonic cleaning available for suitable removed components. Request an intake cleaning assessment to arrange this alongside the work.

Installation and ECU tuning are not included in the plate price. The mail-in ECU tuning service is charged separately when selected.
