Why Are Diesel Fuel Injectors Expensive? (they’re not!)

18 May Why Are Diesel Fuel Injectors Expensive? (they’re not!)

Expensive (relatively) vs “Cheap” fuel injectors – what’s the difference?

When shopping for diesel fuel injectors, prices are often one of the first things that come to any buyers’ mind. As you go around researching about how much it costs to replace diesel injectors, you may easily wonder why a small fuel injector can be expensive. Today, we hope to share with everyone reasons that justify the prices demanded by quality fuel injectors. By understanding how a diesel fuel injector is made, how it works, and the important role each injector plays in your engine, you will better understand why quality fuel injectors are slightly pricey and that “cheap” fuel injectors may actually be more expensive in the longer run.

Huge investments go into injector research and development

Firstly, top manufacturers invest greatly in research and development, ensuring a top-notch product. While the simple purpose of the fuel injection system is to deliver fuel to the cylinders of diesel engines, the process in which fuel is delivered may differ between injectors used. To illustrate this, we can compare the differences in injector operation – poorly reputed manufacturers making cheap fuel injectors may not have the same level of technical expertise required to manufacture these highly precise parts. These cheap injectors may be a mere copy of the original and may be known to be noisier and less efficient, hurting both user experience and the environment.

Quality fuel injectors require high-end materials

Cheap injectors may skimp on materials 

Secondly, quality materials are used in injector construction so that the injectors can thrive in the high-pressure environments of diesel fuel injection systems. Top brands like Bosch, Zexel, and Denso will not skimp on materials at the cost of quality, thus you know that in buying from them, you are buying a product designed to last. Materials are carefully selected and each injector is carefully constructed to ensure that they hold up to extreme pressures, allowing them to meet their durability targets. With quality injectors, we help to avoid expensive repairs and allow users to achieve better uptime of their engines. On the other hand, cheap fuel injectors from unreputable manufacturers may be constructed using lousy materials which cannot withstand the high temperatures and pressures within a vehicle’s fuel injection system. As such, these “cheap” injectors may spoil more often and require more frequent replacement, leading to additional costs.

Fuel injectors require high precision in their manufacturing

Inferior manufacturers may not have the required advanced machinery 

Thirdly, injectors are highly intricate pieces of equipment. Injectors have a tolerance of 1 micron, the finest tolerance of any mechanical component on the engine. To be able to manufacture at such precise standards and to afford the exacting quality checks along with it also helps to explain part of the costs of quality fuel injectors. Not just are large sums invested into developing a quality product, the advanced machinery required to manufacture quality fuel injectors are not cheap either. As such, inferior manufacturers are not able to achieve the same precision and quality in their cheap fuel injectors.

Genuine Injectors bring better value

Cheap fuel injectors may be more expensive in the longer run. 

Now that we have explained why quality fuel injectors are expensive, it is only natural that we explain why you should buy from quality brands. Genuine and brand-new diesel fuel injectors from top brands may seem expensive at first glance, but we believe you can get better value for your money in the long run.

A superior injector can deliver significant benefits, including longevity and greater fuel efficiency. The key lies in the exacting standards during injector manufacturing, which a lower-quality producer is simply unable to match. Not just must injectors be able to withstand and thrive under extremely high injection pressures, the injector also needs to do so with accuracy and precise variability such that it can best respond according to the engine’s operating state. According to research by Bosch, in travelling 100,000km on heavy diesel trucks, using genuine Bosch nozzles can save you 1,780 litres of diesel as compared to using nozzles by less optimal brands. Bosch has shown through research that their quality fuel injection parts can benefit users through better fuel efficiency, which will bring significant savings in operational costs. Adding on, using quality injectors will also bring further savings arising from higher uptime and reduced need for costly repairs which may result from using an inferior cheap fuel injector. These are the advantages even before we factor in the environmental impact of improved emissions output, which will make choosing our range of quality fuel injectors from world leading brands like Bosch, Zexel, and Denso the even more obvious choice. What may come across as “expensive” at first glance, may prove to deliver outstanding value over the long run.

The diesel fuel injection system may cost as much as 30% of the total engine, illustrating the technical demands in producing this relatively small system. Cheap fuel injectors may require more frequent replacement, operate at poorer efficiency, and in more unfortunate cases, may have leakages or other problems that may even result in costly damages to your vehicle’s engine. Having invested in a quality diesel engine, it is important to repair or replace only with genuine diesel fuel injectors so that the system will be able to function well and function long.
