4JJ3 PreLine-Plus + ProVent Dual Kit – PLPV645DPK

Direction Plus PreLine-Plus + ProVent 4JJ3-TCX Specific 100% Water • 98% Oil Separation Free Express AU Shipping

Complete fuel & crankcase protection for Isuzu 4JJ3 engines.

If you’re running a 4JJ3-TCX, clean fuel and controlled crankcase ventilation aren’t optional — they’re critical. The PreLine-Plus + ProVent Dual Kit (PLPV645DPK) combines first-stage fuel filtration with high-efficiency oil vapour separation to protect injectors, pumps, turbo and intake components.


🛠️ Vehicle Compatibility
  • Isuzu D-MAX – 4JJ3-TCX (2020-on)
  • Isuzu MU-X – 4JJ3-TCX (2020-on)
  • Mazda BT-50 – 4JJ3-TCX (2020-on)
Vehicle-specific kit engineered for clean bolt-on installation. If unsure, send us your VIN or rego and we’ll confirm before dispatch.

💧 PreLine-Plus Pre-Filter – Fuel System Protection
  • 100% water separation (tested on 300µm droplets)
  • 98% particle filtration at 30 microns
  • In-cab multi-stage water alarm — visual & audible warning
  • Stops rust, corrosion & injector damage before it starts
  • Spin-on filter design for quick, clean servicing

Designed for harsh Australian conditions — remote fuel, questionable servos and heavy touring use.

  • Up to 98% oil separation efficiency
  • Keeps oil and soot out of intake, turbo and intercooler
