Mazda B4000
Parts fit 1994 to 2010. Owner reports cover 1996 to 2025, mapped to 1 NHTSA name, so vehicles of very different ages are counted together.
61 of 293 parts name an engine. The other 215 fit any, so choosing one here only narrows those 61.
What owners report
6 of 12 components, the largest by share, together 57.5% of all mentions. 540 reports filed with NHTSA from 1996 to 2025, read through 14 name and year queries against 1 source name. A report can name more than one component, so these 540 reports carry 675 mentions, 1.25 for each report, and every share below is of those 675. 12 more mentions were filed as unknown or other and are excluded from both the rows and the total.
What we can sell for it

Where the two lists meet

Tires are 11.7% of reports and we stock no parts in Tires & Wheels for it.
