M&D Distributors - About Us

Pioneers in the Diesel Component Business

Service Since 1943

Magneto and Diesel Injector Service, Inc. was founded in 1943 near the banks of the Houston Ship Channel at the heart of Houston, Texas' industrial area. We became the premier source for Diesel-related parts and service during its early years, providing injector and magneto repair services to the shipping and rail industries that served Houston during World War II.


Growing & Expanding

As our business grew, we developed relationships with key manufacturers in the Diesel industry. Bosch, Honeywell-Garrett, Federal Mogul, Cummins, Stanadyne, Holset, BorgWarner, Parker Racor, Baldwin Filters, and many more are now part of our family of products for which we provide sales and services.


Moving Forward...

Today, we are headquartered in Humble, Texas, a suburb of Houston. We are now known as M&D Distributors and have expanded to eight locations in Texas and Louisiana, with sales, service, and distribution responsibilities in Texas, Oklahoma, and Louisiana. The heart of our business remains Diesel fuel injection, but along with adding locations and territories, we have also added to our capabilities to serve out customers' needs for turbochargers, engine parts, filtration, and much more.
