Manifold Nut & Stud Kit, 70-74* 240Z-260Z
You can choose a Z-Car from your garage, or from the selections above, to filter the store or check part fitment.
Part #:15-8080
Price: $40.87
  • (10) Short Manifold Stud
  • (1) Medium Manifold Stud (for rear engine slinger and rear bypass tube)
  • (6) Long Manifold Stud (for manifold spacers)
  • (17) Manifold Nut

The intake & exhaust manifold nuts and studs will stretch and weaken with use, and should be replaced when installing any header. This simple kit comes with all of the manifold studs and nuts needed to mount your manifolds to the cylinder head.

*Application Notes:
We recommend this kit for all 70-74 240Z-260Z's with E31 or E88 Cylinder Heads. 73-74 models originally used bolts along the top of the intake manifold; however, we have found that studs make manifold installation easier. For all later L-Series heads (N42, N47, P79, P90), follow the fuel system you are choosing. Regardless of which 70-83 Z you have, if you are using an N42, N47, P79, or P90 head with a carburetor setup, you will need this kit. If you are using an N42, N47, P79, or P90 head with a fuel injection manifold, then you need part 15-8081 (see Related Items).

Related Item:
All L-Series heads also have 6 "spacers" that hold down both the intake manifold and the exhaust manifold/header at the same time. Check to see if these are worn and in need of replacing also (see part 14-0373 in Related Items). For a complete kit including the spacers and the rest of the hardware, see 15-8082 in Related Items.
