Inlet Manifold Gasket and Manifold Bolt Kit - Complete Intake Sealing and Securing Solution
This inlet manifold gasket and manifold bolt
kit provides everything required to correctly reseal and refit your intake
manifold. The set includes:
8 x Inlet manifold gaskets
10 x Manifold bolts (securing elements)
Fits:
Diagram ref no 5 and 6
Designed to restore proper intake sealing and ensure secure installation, this kit helps maintain optimal engine efficiency and performance.
What Inlet Manifold Gaskets and Bolts Do
The inlet manifold distributes air evenly to each cylinder of your engine. The manifold gaskets create an air-tight seal between the intake manifold and the cylinder head, preventing vacuum leaks and ensuring the correct air-fuel mixture reaches the combustion chambers.
The manifold bolts, also known as securing
elements, clamp the intake manifold securely in place. Correct clamping force
is essential to:
- Maintain consistent air pressure
- Prevent vacuum leaks
- Support stable idle and acceleration
- Protect engine performance
- Avoid unmetered air entering the system
Without properly functioning gaskets and correctly torqued bolts, the intake system cannot operate efficiently.
Why Inlet Manifold Gaskets and Bolts Fail
Over time, inlet manifold gaskets are exposed
to:
- High engine temperatures
- Continuous thermal expansion and contraction
- Oil vapour and carbon exposure
- Long-term compression fatigue
This can cause gaskets to harden, crack or shrink, resulting in air leaks.
Manifold bolts can also stretch, corrode or lose clamping force, especially if reused after removal. Modern engines often use torque-to-yield securing elements, which are designed for single use. Reinstalling old bolts can compromise sealing integrity.
Common symptoms of failing intake manifold
gaskets include:
- Rough idle Hesitation during acceleration
- Lean mixture fault codes
- Whistling or hissing noises
- Reduced fuel efficiency
- Check engine light illumination
Why You May Need This Kit
If you are removing or replacing your intake manifold, it is essential to install new gaskets and securing bolts to ensure proper resealing. Reusing old gaskets or bolts increases the risk of air leaks and repeat labour.
This inlet manifold gasket and bolt kit is
ideal for:
- Intake manifold removal during engine repair
- Resolving vacuum leak issues
- Addressing lean mixture fault codes
- Preventative maintenance
- Engine rebuilds or carbon cleaning work
Replacing both the sealing gaskets and the securing bolts at the same time ensures correct clamping force and long-term reliability.
