FAQ
How many gaskets do I need?
Sold individually—order two for both cylinder heads.
Is this the 18 mm dowel version?
Yes. If your engine uses 20 mm dowels (many 2006+), use Mahle 54579A/HS54579 instead.
What are the thickness and bore?
Approx. 0.060" thickness (1.52 mm) and 3.83" (97.40 mm) bore.
Does it include head bolts/studs?
No—fasteners are sold separately. Follow factory torque/angle specs.
