Siemens is one of the most trusted names in diesel fuel systems, supplying OE injectors to manufacturers worldwide. Whether you're running a Ford Ranger, Ford Everest, or Mazda BT50 with the 2.2L P5AT or 3.2L P5AT engine, the Genuine New Siemens Injector gives you proven engineering and quality control straight from the source. Siemens injectors are built to tight tolerances and go through rigorous testing before they leave the factory. Every unit is checked for spray pattern, flow rate, and sealing performance. That's how they guarantee consistent fuel delivery and long service life.
Vehicle Fitment
Suits Ford Ranger, Everest and Mazda BT50 fitted with 2.2L and 3.2L P5AT engines (non-DPF models).
Why Injector Precision Matters
Your diesel's injectors do one of the most critical jobs in the engine. They deliver precise fuel at incredibly high pressure, often exceeding 2000 bar in modern common rail systems. At that pressure, the injector has to atomise fuel into a fine mist and spray it in exactly the right pattern, at exactly the right moment, thousands of times per minute. When injectors start failing, you'll notice hard starting, rough idle, black smoke from the exhaust, loss of power, or a sudden jump in fuel consumption. These symptoms tell you it's time for replacement.
Genuine vs Aftermarket
This is a genuine Siemens unit, not an aftermarket copy. You're getting the same injector that comes from the factory, which means proper spray pattern, correct fuel atomisation, and reliable performance. Cheap aftermarket injectors often have poor spray patterns that lead to incomplete combustion, wasted fuel, and carbon buildup. They might work when you first fit them, but they don't last. Poor quality internals wear quickly, and you're back to square one within months. These injectors are built to handle Australian conditions: dusty roads, heavy loads, and long highway stretches between fuel stops.
Replace Your Fuel Lines Too
When you're replacing injectors, it's the perfect time to fit new high-pressure fuel lines as well. After 120,000-150,000km, the steel inside these lines starts breaking down. Those microscopic particles go straight into your new injectors and cause premature wear. You won't see it happening, but the damage builds up. Fresh lines mean your new injectors stay clean and last longer.
What Causes Injector Failure
Injector failure often comes down to contaminated fuel or water in the diesel. Even small amounts of water cause internal corrosion and damage the precision components inside. Regular fuel filter changes and using quality diesel go a long way. If you've had fuel contamination issues in the past, make sure your fuel system is properly cleaned before fitting new injectors. Otherwise, you're just putting new parts into a dirty system.
Critical Installation Tips
Never bend the fuel lines out of the way when you're pulling the rocker cover or other components. Bending weakens them, and you'll end up with cracks and leaks not long after. It's a common mistake that causes headaches down the track. Take the extra time to disconnect them properly.
When you're fitting the injectors, use new copper seals and torque everything to spec. Don't skip this step. Incorrect torque can cause leaks or damage the injector body. After installation, you'll need to prime the fuel system and bleed any air out of the lines. Air in the system causes rough running and can make you think the new injectors aren't working properly when it's just trapped air.
Warranty
Direct replacement with OE fitment and full statutory warranty. Warranty covers manufacturing defects and faulty materials, giving you peace of mind that you're covered if anything goes wrong.
