Can anyone tell me the bolt size for the Injen intake heat shield? Thanks.

5/16 - 18 bolt

Hey! I needed this info too! Thanks!

another thing to think about when I originally put this on, after a while I noticed a loud rattle under the hood. all of the bolts had worked their way out. So this time put some lock tite on them and torqued them down good and tight. Hopefully they dont work their way loose again.

locking washers ftw
