Why Choose Our Cylinder Heads?

A cylinder head is crucial for the efficiency and performance of your engine. It contains the intake and exhaust valves, spark plugs, and fuel injectors, which are vital for the engine’s operation. Our heads are designed to handle the extreme pressures and temperatures within the combustion chamber, ensuring optimal engine performance.

Signs You May Need a New Cylinder Head:

1. Weak Engine: Poor fuel efficiency, sluggish acceleration, or difficulty climbing steep inclines may indicate a cracked cylinder head.
2. Oil Leakage: Puddles of oil under your vehicle can signal a leaking cylinder head.
3. Coolant Leakage: Overheating warnings or coolant puddles may indicate a cracked head.
4. Engine Misfires: Repeated engine failures or trouble starting may be due to cylinder head damage.
5. Smoke: White smoke from the engine suggests severe cylinder head failure.
