Why an Intercooler Matters

Turbochargers compress air before it enters the engine.

As boost pressure increases:

• Air temperature rises
• Air density decreases
• Combustion efficiency drops
• Performance can decline

The intercooler cools compressed air before it reaches the intake manifold, helping maintain proper engine performance.
