Head bolts are "stretch bolts" or "torque-to-yield bolts". Which is to say they are torqued to spec, then tightened down more and "stretched" into the correct position. This means that once they are removed, they cannot be used again. If either head is coming off, install these OEM M12x1.5x177mm head bolts with washer to avoid issues with snapped bolts, and/or an improperly seated head.

Sold individually. 8x bolts required per head. 16x bolts required per engine.

Note: OEM items are not returnable, so to avoid disappointment, please email your VIN to us at [email protected] to be sure that this will fit your particular application.
