How it works

Match the number, not the guess

Three ways to find the correct part. Start with the OEM number — it is always in the vehicle service manual and printed on the part itself.

1. Search the OEM number

The most accurate method. Bosch 5WK96667C, Mercedes 0042702951 — paste it into the search bar and we match the exact part.

Fastest · 1 step

2. Browse by vehicle brand

Pick your make and engine family. Every category shows only parts verified for that platform.

By platform

3. Ask a specialist

Send the VIN or engine code. A fitment specialist replies within 4 business hours with the verified part.

Trusted by diesel shops

“Ordered a 5WK96667C for a 755E at 08:00, it was on my desk the next morning. Fit and function matched the OE Bosch part to the last wire.”

M. Kowalski · Fleet tech, Milwaukee

“The part-number search is the real deal. I typed 0009053403 and got exactly the Mercedes part — no digging through 12 SKUs with the same name.”

R. Alvarez · Diesel shop, Phoenix

“Returned one part that didn't fit — refunded in 3 days, no questions, no return form. I'm a customer for life.”
