As you will notice, a good number of applications require manifold gasket # ABF871.
To make life a little easier for you, you can order this gasket right along with this kit (1 per kit).
For that purpose, you need to make a selection through the "Manifold gasket?" drop-box above the Add to cart button.
if you don't want, or don't need, the manifold gasket, simply select "No thanks" at that same drop box.
According to SU nomenclature, this is a co-called Service Kit.
