ARP 400-8023 10x Mazda Protege Exhaust Manifold Stud Kit M8 x 1.25 x 45mm Bolt

Description

10x studs, 10x nuts, and 12x washers (two extra washers from a previous kit included). Threaded in but never torqued. Will fit anything that is M8 by 1.25 thread and 45 mm long.
"They are made of ARP's stainless 300 and are impervious to the rust and corrosion that plague ordinary fasteners. The studs feature a unique nut starter nose and a hex broached tip, allowing them to be easily installed using an Allen wrench."
Depending on your exhaust manifold, you may need to use hex socket-head screws in one or two locations instead of the studs.
