Step-by-Step Installation Procedure


1.Remove the Old Components:Inspection step.

Carefully extract the old injector. Crucial: Ensure the old copper washer/seal ring is removed from the injector seat. If left inside, double-stacking washers will cause severe fuel leakage and engine misfires.


2.Clean the Injector Seat:Preparation step.

Use a dedicated injector seat cleaning brush and tool to remove any carbon buildup, rust, or debris from the bottom of the well. The seat surface must be perfectly clean and smooth for a proper seal.


3.Prepare the New Injector:Pre-lubrication.

Remove the protective caps from the new injector. Always install a brand-new copper washer and replace the rubber O-rings. Lightly lubricate the O-rings with clean engine oil or specialized high-temperature injector grease to prevent tearing during installation.


4.Insert the Injector:Placement.

Carefully lower the injector straight into the cylinder head well. Push down firmly by hand until it bottoms out on the seat. Never force it down using a hammer or by tightening the clamp bolt.


5.Torque the Hold-Down Clamp:Critical Specification.

Install the injector hold-down clamp and bolt. Tighten the bolt using a calibrated torque wrench to the exact manufacturer-specified torque rating. Under-tightening causes blow-by gases; over-tightening can crack the injector body or cylinder head.


6.Connect High-Pressure Lines & Wiring:Final assembly.

Reinstall the high-pressure fuel supply lines and finger-tighten the nuts first, then torque them to specification. Reconnect the electrical wiring harness connector until it securely clicks into place.

Q&A

Q1: Are your fuel injectors genuine Bos-ch/OEM, or are they aftermarket replacements?

A: We offer both options depending on your market needs. We supply 100% Genuine Bos-ch brand new injectors in original packaging, as well as premium high-quality aftermarket replacements manufactured to exact OE (Original Equipment) specifications using top-grade internal components. Please specify your preference when requesting a quote.

Q2: How do you guarantee the quality of your fuel injectors?

A: Quality is our top priority. Every single injector goes through a rigorous quality control process before shipment, including:

  • High-pressure leakage testing.

  • Precise fuel delivery and flow-rate calibration on advanced test benches.

  • Nozzle atomization performance checks. We ensure that every injector arrives ready for stable, plug-and-play installation.

Q3: What is your warranty policy?

A: We stand behind our products. Our fuel injectors come with 12-month warranty (depending on the product series) against manufacturing defects from the date of purchase. Note: The warranty does not cover failures caused by fuel contamination, improper installation, or lack of regular fuel filter maintenance.

Q4: What is your Minimum Order Quantity (MOQ) and lead time?

A:

  • MOQ: For sample orders or popular models (like 0445120333 or 0445120078), our MOQ can be as low as 1 to 4 pieces.

  • Lead Time: If the items are in stock, we typically ship within 2–3 business days after receiving payment. For larger or bulk production orders, the lead time generally ranges from3–7 days.
