Early Rotary & 1979-85 Mazda RX-7 : Mazda OEM Parts

For over 45 years we've been gathering an sizeable collection of various Mazda OEM components and parts. Many of the parts in this section are new hard-to-find parts, superseded parts, left-over from a R&D project, etc...and we've gathered them up and listed them in this section of the website. Many of these parts can be used on several different vehicle applications, model years, models, etc....and we don't have the resources to list all the possible uses for each part. Many parts are limited to stock on-hand and feature special pricing, no backorders! We've included the Mazda OEM part number and a brief description and photograph of each part, if you have a question regarding a specific part we encourage you to search the web for specific application information, or contact us prior to placing your order.
