About Fit My Parts

Fit My Parts reads automaker owner's manuals and republishes the parts facts they print, with page citations.

How the site works

Every value on a car page is copied from that model year's official owner's manual, with the page number linked so you can check it. Battery group sizes come from the Battery Council International chart. Nothing is estimated: if a manual leaves something out, the page says so. Details are on the methodology page.

Corrections

If a figure is wrong or a source has changed, email hello@fitmyparts.com with the page and a link. Corrections go into the data file and the check date updates with the next build.
