Heavy Duty Manifold Stud & Nut Kit, 70-74* 240Z-260Z

Image and price will be updated when the new studs arrive.

Includes:

• (10) Short Manifold Stud (Upgraded! See Description)
• (7) Long Manifold Stud (for manifold spacers & top rear stud) (Upgraded! See Description)
• (17) Manifold Nut (uses 13mm socket instead of 12mm)

Description:
The intake & exhaust manifold nuts and studs will stretch and weaken with use, and should be replaced when installing any header. To help alleviate this issue, these studs have been improved and upgraded! This simple kit comes with all of the manifold studs and nuts needed to mount your manifolds to the cylinder head.

Upgraded Studs!

• Heavy Duty, less prone to breaking
• 10.9 Hardness (stock studs are 8.8 Hardness)
• CNC Machined for superior finish and accuracy
• Made to Factory Specifications
• Zinc coating for corrosion resistance (like factory units, appearance will vary)

*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 15-8087 (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 15-8088 in Related Items.
