WHY IS IT IMPORTANT TO DISTINGUISH BETWEEN THE DIFFERENT TYPES OF INJECTORS?

In the world of diesel engine maintenance, choosing the right injector is essential to ensure top performance, optimized consumption, and compliance with emissions regulations. However, among the available options—new, remanufactured, and overhauled injectors—it’s easy to get confused.

Each type has different characteristics, benefits, and costs, and being able to tell them apart is crucial for making an informed choice, especially for workshops that want to offer high-quality service to their customers.

 

BRAND NEW DIESEL INJECTORS: MAXIMUM EFFICIENCY AND MANUFACTURER’S WARRANTY

New injectors are the most straightforward—though also the most expensive—solution for those seeking top performance and long-term durability. These are components designed and assembled from scratch, with tolerances and materials guaranteed by the original manufacturers.

Let’s look at the main advantages of new injectors:

1. Optimal performance: they ensure uniform, precise combustion with maximum efficiency.

2. Durability over time: materials are new and guaranteed by the OEMs.

3. Full warranty: official manufacturer coverage, generally 12 months.

4. Perfect compatibility: no risks related to assembly or out-of-spec parameters.

 

When should you choose a new injector?

● For next-generation engines for which the parts needed for overhauling are not available.

● When it is necessary to certify the reliability of the repair, or when working on vehicles still under warranty.

● When the higher cost is not a determining factor.

Naturally, the main drawback of choosing new injectors is the higher price compared to remanufactured or overhauled alternatives.

 

OVERHAULED AND REMANUFACTURED DIESEL INJECTORS: A BALANCE BETWEEN QUALITY AND VALUE

Rebuilt injectors are an alternative solution that offers an excellent compromise between performance and cost. In the rebuilding process, the injector is completely disassembled, cleaned, and inspected. Wear parts—such as valves, seals, O-rings, springs, and nozzles—are replaced with new, high-quality spare parts.

The injector is then reassembled and tested on a test bench to ensure performance equivalent to that of a new injector.

 

Advantages of REDAT reman injectors:

A. Controlled quality: each injector is individually tested in the workshop.

B. New REDAT components: only high-quality parts.

C. Cost savings: the average price is lower (on average by 40%–50%) compared to new.

D. Environmental sustainability: by reusing the original body, material waste and environmental impact are reduced.

 

When should you choose a rebuilt injector?

●        When budgets are tight but high quality is required.

●        For vehicles no longer covered by the official warranty.

●        When you want a product with characteristics equivalent to the original, but more affordable.

REDAT remanufactured injectors are tested on Hartridge and Bosch test benches and are guaranteed by our warranty, offering performance and safety comparable to those of a new product.

 

HOW THE CHOICE CHANGES BASED ON THE TYPE OF ENGINE AND WORKSHOP

The decision between new, remanufactured, or overhauled injectors also depends on the type of clientele and the workshop’s activity.

For specialized workshops and modern fleets:

It’s better to choose new injectors or high-quality remanufactured units to ensure optimal performance, compliance with environmental regulations, and maximum reliability and service life.

For generalist workshops and older vehicles:

Professionally overhauled injectors can be a good compromise and offer the customer the best price-to-quality ratio.

For customers sensitive to environment and sustainability:

Remanufactured injectors are the ideal solution: they combine quality, savings, and environmental respect.
