INFINITI Cylinder Heads

The cylinder head plays an essential role in your INFINITI's engine performance, managing the precise dance of fuel, air, and exhaust gases. Located at the top of the engine block, this sophisticated component contains the valves and passages that control combustion timing. Understanding how cylinder heads function - and recognizing early warning signs of wear - can prevent major engine problems and save thousands in repair costs.

Identify Common Cylinder Head Problems

Many INFINITI owners experience cylinder head issues between 80,000 and 120,000 miles, particularly in the Q70 and QX80 models. Warning signs include white exhaust smoke, coolant loss, dropping oil levels, and decreased engine performance. Regular maintenance helps prevent premature wear, but extreme temperatures and poor cooling system maintenance accelerate deterioration.

Choose Quality Parts for Lasting Performance

At INFINITI of Tucson, we recommend genuine INFINITI cylinder heads over aftermarket alternatives. Generic replacement parts often suffer from inferior materials and inconsistent manufacturing tolerances. Factory-original cylinder heads integrate perfectly with your existing serpentine belt system and maintain proper engine timing.
