    Hello. Today while checking my son’s Prius engine fluids for a long trip, I noticed his intake manifold is missing one bolt. Not sure how this happened. My local hardware store did not have any metric bolt that could be matched.

    Do you know what is the right bolt that goes in here? I probably can order it online.
    Thank you for your help.

    You can probably get the bolt at any Toyota dealer for a couple bucks, that is the EGR Pipe in the picture.

    At your Toyota dealer it is a 91551-80616, but it's also a bog-standard M6 if I recall correctly; no idea why the local hardware didn't have 200 of them.

    Home Depot has 'em: M6-1.0 10 or 12mm zinc plated flange bolt. Lowes probably does as well.

    What I would do?

    Get a generic bolt and swap it out for one in a non-critical location, like securing a harness bracket.

    I would accept just about any odds that an M6 bolt from the local Tru-Value will keep that pipe elbow from falling off that manifold. :)

    The bolt is J.I.S. (Japan Industrial Standard) M6x1.0x16mm in length with a 10mm hes washer flange head. I have over 50 of them in my supply of spare parts.

    I've seen them in the drawers at Home Depot in ISO 8.8 grade, which is what Toyota uses for this application. 20mm length will work just fine, since they are through bolts.

    Mine are 10.9 grade which is higher, but not necessary.
