Intercooler Upgrades

Upgrade you Intercooler for lower EGTs & More Power





Intercooler An intercooler is positioned either in front of or behind the engine's raditor. Since compressing air increases the temperature of the air (think PV=NRT), an intercooler is used to cool the air charge before it is forced into the engine. Compressed air travels from the turbocharger, through the intercooler, and then through intake of the engine. Cooling helps lower EGTs and increase performance, since cooler air is denser.


Otherwise Known As:

Intercooler, charge air cooler

How It Works:

While OEM intercoolers work well, many aftermarket companies have developed more efficient intercoolers that are capable of handling much higher boost pressures. By upgrading to a high flow, efficient intercooler, you gain a noticeable power increase, improved fuel economy, and a big drop in exhaust gas temperatures. If your EGTs have been known to run a little hot, a new intercooler just may be the solution.


• Lower intake air temperatures.
• Lower exhaust gas temperatures.
• Increased performance & fuel economy.
• Ability to run higher boost pressures.
• Less pressure drop from intercooler inlet to outlet.


• Expensive.
• Requires some dismantling of front clip to install.

Possible Problems:

• If you are running high boost pressures, ensure your intercooler is rated to handle it.

Est. Gains:

• Around 20 hp, but results could be greater depending on application/conditions.
• Up to a 200 degree F drop in exhaust gas temperatures.


All Power Stroke, Cummins, & Duramax engines.

Additional Info:

Stock intercoolers have been known to "balloon" and leak when boost pressures get too high.
