FUNCTIONS:
1. Distributes gases efficiently – Ensures even flow of air (intake manifold) or exhaust gases (exhaust manifold) to and from the engine cylinders.
2. Improves engine performance – Optimizes airflow to enhance engine power, fuel efficiency, and smooth operation.
3. Supports combustion – The intake manifold delivers the correct amount of air (or air-fuel mixture in some engines) to each cylinder for efficient combustion.
4. Channels exhaust gases – The exhaust manifold collects exhaust gases from the cylinders and directs them to the exhaust system.
5. Reduces emissions
WHY IT MUST BE REPLACED?
1. Cracks or warping due to excessive heat.
2 Air or exhaust leaks causing poor engine performance.
3 Corrosion or physical damage.
4 Damaged mounting surfaces or threads.
5 Internal blockage or severe we
