Description:
The thermal cycle that manifold hardware is exposed to every time you run your car causes wear to these bolts, studs, etc. In the short term, it can cause nuts and bolts to loosen; however, over a longer period of time, hardware stretches, weakens, and can even break (the latter usually happens during removal). Unfortunately, there is no getting around the long term effects of thermal cycling, which is why we recommend replacing old hardware whenever you have the manifolds removed (for instance, when installing one of our performance headers). To help alleviate this issue, the studs in this kit, which are the most susceptible to wear, have been improved and upgraded!

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:
This kit is for all 75-83 280Z-280ZX's with N42, N47, P79, or P90 Cylinder Heads, running fuel injection. If you are using an N42, N47, P79, or P90 on your 70-74 240Z-260Z with fuel injection, you need this kit. It will not work with early cylinder heads (E31, E88). If you are installing a carburetor on an N42, N47, P79, or P90, you will need part 15-8086 or 15-8088 (see Related Items).

**Notes:
Like the long intake manifold bolt, the short manifold bolt has also received drastic price increases from Nissan recently. We were able to locate a suitable replacement bolt for the OEM part at roughly the same cost as prior to the increases. The replacement short bolt will have a slightly different appearance compared to the image on this page, but is functionally the same.
