You asked and we listened! We assembled this kit thanks to your feedback.
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). This kit includes:
- (12) Manifold Studs
- (12) Manifold Washers
- (12) Manifold Nuts
- (2) Long Intake Manifold Bolts
- (2) Short Intake Manifold Bolts
- (4) Thick Intake Manifold Bolt Washers
- (6) Manifold Spacers
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 15-8080 or 15-8082 (see Related Items below).
