• Mitsubishi Triton – 4N15 2.4L 4-Cylinder Turbo Diesel | 2015–2023
• Mitsubishi Pajero Sport – 4N15 2.4L 4-Cylinder Turbo Diesel | 2015–2023

✅ Direct fit for 4N15-powered Triton and Pajero Sport models

How It Works: Installed AFTER your factory filter, the Fuel Manager Post-Filter captures fine contaminants that the OEM filter misses. This ultra-fine 2-micron filtration ensures only the cleanest fuel reaches your 4N15's precision injectors.

Key Features:

• 2-micron filtration — captures fine contaminants missed by factory filter
• Clear bowl — inspect and drain water in seconds
• No-bypass design — ensures 100% filtered fuel supply
• Protects against ultra-fine particle contamination
• Additional water separation capability
• Extends injector and pump lifespan
• Maintains optimal fuel pressure

💡 Why This Matters: The 4N15 common rail system operates at extreme pressures (2000+ bar) with microscopic tolerances. Even particles that pass through your OEM filter can cause expensive damage. This post-filter provides final-stage protection—preventing $10k+ injector and pump damage.

How It Works: The ProVent separates oil mist and blow-by gases before they enter your intake system. Keeps your intake, turbo, and intercooler clean—regulating crankcase pressure for smoother running on your 4N15.

Key Features:

• 98% oil separation efficiency
• Keeps intake, turbo, and intercooler clean
• Prevents oil and soot entering clean air intake
• Reduces oil mist, blow-by, and exhaust smoke
• Regulates crankcase pressure for smoother running
• Minimizes oil consumption
• Reduces carbon build-up
• Protects turbocharger and EGR system

💡 Why This Matters: Oil vapour causes carbon deposits that restrict airflow and coat sensors. In the 4N15, keeping the intake clean is critical for maintaining performance and preventing expensive intake system repairs. Together, these systems eliminate the top causes of injector failure and carbon build-up.

Factory filters have limitations. While they provide baseline protection, ultra-fine particles and water can still pass through. Oil vapour from blow-by accumulates in your intake. This dual kit addresses both problems.

Benefits:

• 💰 Prevents $10k+ injector and pump damage
• 🔍 2-micron post-filtration catches what OEM filters miss
• 💧 Additional water separation for extra protection
• 🌿 98% oil separation keeps intake system clean
• 🚫 No-bypass design ensures full protection always
• 🛡️ Dual-stage defense — fuel and intake protection

💡 Post-Filter vs Pre-Filter: A pre-filter protects your OEM filter by catching bulk contamination first. A post-filter provides ultra-fine filtration AFTER the OEM filter for maximum injector protection. The ProVent handles intake protection. Together they provide comprehensive 4N15 defense.

Fuel Manager Post-Filter:

• Check clear bowl regularly for water accumulation
• Drain water bowl as needed (simple drain tap)
• Replace filter element per vehicle service schedule
• Visual inspection takes just seconds
• Water drainage takes just minutes

ProVent Catch Can:

• Check oil level every 5,000–10,000 km
• Drain collected oil via drain tap when needed
• If using sump return line, oil automatically recirculates
• Replace filter element every 40,000 km (replacement elements available)

💡 Pro Tip: Regular maintenance is simple and takes minutes. The clear bowl and drain taps make servicing quick and easy. Keep your 4N15 protected with minimal maintenance effort—especially important for the work these vehicles do.

Q: Will this void my Mitsubishi warranty?

A: No. Aftermarket protection devices don't void warranty under Australian Consumer Law. These systems protect your engine without interfering with factory components.

Q: Does this fit both Triton and Pajero Sport?

A: Yes! This kit is specifically designed for both Triton and Pajero Sport models with the 4N15 2.4L turbo diesel engine (2015–2023). Direct fit for both vehicles.

Q: What's the difference between a pre-filter and a post-filter?

A: A pre-filter installs BEFORE your OEM filter and catches bulk contamination first. A post-filter installs AFTER your OEM filter and provides ultra-fine filtration (2 microns) as a final defense. Many owners run both for maximum protection.

Q: Do I need both a post-filter AND a catch can?

A: Yes, they protect different systems. The post-filter protects your fuel injection system from ultra-fine particles, while the ProVent protects your intake, turbo, and EGR from oil contamination. Together they provide comprehensive 4N15 protection.

Q: Why is the 4N15 particularly vulnerable?

A: The 4N15 is a modern common rail diesel operating at extreme pressures (2000+ bar) with tight tolerances. It's highly sensitive to both fuel contamination and carbon build-up. This dual protection system addresses both vulnerabilities.

Q: Will this restrict fuel flow or affect performance?

A: No. The post-filter is designed to provide ultra-fine filtration without restricting fuel flow. When properly maintained, it has no impact on performance while providing superior injector protection.

Q: What is the no-bypass design?

A: With a no-bypass design, even if the filter becomes blocked, contaminated fuel cannot bypass the filter and reach your engine. This ensures your 4N15 injectors are always protected, unlike systems that allow bypass when filters are clogged.

Q: How often do I need to replace the filter elements?

A: Replace post-filter element per your vehicle service schedule (typically every 10,000–20,000 km). Replace ProVent element every 40,000 km. The clear bowl allows visual monitoring of post-filter condition.

Q: Can I install these systems myself?

A: If you're mechanically competent and comfortable working with fuel lines, yes. Most DIYers complete installation in 4-5 hours for both systems. Otherwise, any qualified mechanic can handle it. Detailed installation guides are included.

Q: Does the ProVent return oil to the sump automatically?

A: The kit includes components for an optional sump return line. You can configure it to either: (a) collect oil in the catch can for periodic draining, or (b) return clean oil back to the sump automatically. Your choice based on preference.

Q: How much does 4N15 injector replacement cost?

A: Common rail injector replacement on the 4N15 can easily exceed $10,000 when you include parts, labor, and associated repairs. The post-filter is cheap insurance against this expensive failure.

Q: Is this suitable for towing and heavy-duty use?

A: Absolutely. This dual protection system is built for tough Australian conditions including towing, heavy loads, and variable fuel quality. Many commercial Triton/Pajero Sport operators consider this type of protection essential.

Q: Can I buy these systems separately?

A: Yes, you can buy the post-filter or catch can individually, but the combo kit offers better value and comprehensive protection. Together they defend both your fuel system and intake system.
