Our Story

Built on Experience, Driven by Quality

Alter Diesel was founded with a simple mission: to provide diesel injection system professionals with the spare parts they need — at the right quality, at the right price, delivered on time.

Over the past decade, we have built deep expertise in Bosch and Delphi common rail injector components, including control valves, piezo actuators, EUI actuators and rubber repair kits. Every product we supply is held to OEM-equivalent standards before it reaches our customers.

Based in Nilüfer, Bursa — one of Turkey's most important industrial hubs — we combine local manufacturing strength with a global distribution mindset. Our customers range from independent repair workshops to large-scale distributors across Europe, the Middle East, Africa and beyond.

What We Stand For

Mission & Vision

🎯
Our Mission

To deliver OEM-quality diesel injector spare parts that help repair professionals do their best work — with confidence, consistency and zero compromise on precision. We exist to make every repair last.

🌍
Our Vision

To become the most trusted name in diesel injector components on the global market — recognized not just for what we supply, but for how reliably and honestly we do business with every partner, in every country.

How We Work

Our Core Values

01
Precision First

Every part we produce is measured and inspected against OEM specifications. We don't ship anything we wouldn't install ourselves. Tolerances matter — and we take them seriously.

02
Honest Partnership

We believe long-term business is built on trust. That means transparent pricing, straightforward communication and standing behind everything we ship — no exceptions.

03
Global Mindset

Our customers work in different languages, time zones and markets — and we adapt to all of them. Responsive support, flexible logistics and multilingual communication are part of who we are.

04
Continuous Improvement

The diesel injection market evolves constantly. We invest in testing equipment, expand our product range and refine our processes — so our partners always have access to the best available solutions.

05
Fast Response

Downtime costs money. We understand urgency — that's why we maintain ready stock, prioritize quick order processing and work hard to get parts where they're needed, fast.

06
Custom Solutions

Not every customer has the same needs. Whether it's a specific OEM number, a non-standard quantity or a private label request — we're flexible, and we make it work.
