Ryco Pre-Filter Kit – D-MAX, MU-X & BT-50 (2020+)

Ryco 10-Micron Filtration 99% Water Removal 4JJ3-TCX Specific Free Express AU Shipping

Heavy-duty fuel pre-filter protection for modern Isuzu and Mazda 4JJ3 diesel engines.

The Ryco RC645DPK Pre-Filter Kit is engineered specifically for Isuzu D-MAX, MU-X and Mazda BT-50 (4JJ3-TCX) vehicles. It provides a critical first line of defence against water contamination, poor fuel quality and injector damage — all common causes of expensive diesel failures.

Designed for harsh Australian conditions, this kit is ideal for touring, towing, off-road use and remote fuel stops.

🔧 Vehicle Compatibility
  • Isuzu D-MAX (4JJ3-TCX) — 2020+
  • Isuzu MU-X (4JJ3-TCX) — 2021+
  • Mazda BT-50 (4JJ3-TCX) — 2020+
Installs in-line before the OEM fuel filter for true two-stage filtration.
💡 Why this kit belongs on your rig
  • Removes up to 99% water and 98% fine particles before the OEM filter
  • Reduces injector wear, pump damage and costly fuel system repairs
  • Built for creek crossings, jerry refuels and variable diesel quality
⚙️ Kit Features
  • High-efficiency 10-micron filter element
  • Silicone-coated media for water resistance and durability
  • Rated to 87 PSI (600 kPa)
  • Wireless water sensor compatible (optional upgrade)
  • Tested to relevant ISO / SAE standards
🛡️ Why you shouldn’t skip a pre-filter
  • Protects injectors and high-pressure fuel pumps
  • Extends OEM fuel filter life
  • Adds peace of mind for touring and remote travel

Fact: A large percentage of diesel fuel system failures are caused by water contamination.

⚙️ How it works

The RC645DPK is installed upstream of the factory fuel filter. Stage 1 removes water and larger contaminants, while Stage 2 (OEM filter) polishes the fuel before it reaches the injectors.
