MPx Intercooler, 08-10 Cobalt SS

Upgrade your Cobalt SS with improved charge-air cooling, durable aluminum construction, and excellent ground clearance—all in a direct bolt-on intercooler.

The factory Cobalt SS intercooler has a relatively small cooling core and plastic end tanks that can develop leaks or become damaged over time. With GM having discontinued the original intercooler, finding a suitable replacement has become increasingly difficult.

The MPx Performance Intercooler provides an excellent solution with a larger bar-and-plate cooling core, durable cast aluminum end tanks, and a vehicle-specific design that offers better ground clearance than the factory unit.

Features & Benefits

• Larger bar-and-plate core: Helps reduce intake air temperatures for more consistent performance, especially on higher-boost applications.

• Cast aluminum end tanks: Stronger, more durable construction than the factory plastic end tanks.

• Improved ground clearance: Designed to sit higher than the original intercooler, reducing exposure to road obstacles and parking stops.

• Direct bolt-on installation: No cutting, welding, or removal of the factory crash bar required.

• Heavy-duty mounting brackets: Constructed from 1/4-inch aluminum and designed to use factory mounting locations.

• Ideal for stock or modified vehicles: An excellent replacement or performance upgrade for turbocharged Cobalt SS models.

Real-World Performance

One CobaltSS.net customer reported an 18°F reduction in intake air temperature, from 116°F with the factory intercooler to 98°F with the MPx intercooler, during testing at approximately 85°F ambient temperature.

The customer also reported no noticeable increase in turbo lag or boost pressure loss. Individual results will vary depending on vehicle modifications and operating conditions.

Vehicle Fitment

• 2008–2010 Chevrolet Cobalt SS Turbo (2.0L LNF): Direct bolt-on installation.

• 2008–2010 Chevrolet HHR SS Turbo (2.0L LNF): Installation requires modifications to the metal bracing behind the intercooler end tanks. Mounting spacers may also be needed. HHR fitment has been reported by customers but has not been independently verified by Modern Performance.
