The APR IC100017 Intercooler System is a OEM-location upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! The APR intercooler improves cooling by up to 23 degrees C in demanding situations, providing gains of 17 HP on a stage 2 equipped vehicle! The system is a direct bolt-on upgrade that requires no trimming and is recommended at every stage of performance.

Benefits of the APR IC100021 Intercooler:

• Dramatically lowers intake air temperature
  Increases horsepower while minimizing power-robbing heat soak.
• Intercooler installed in the best location for this platform
  The APR intercooler utilizes factory air dams for exceptional airflow across the core.
• Use of the OEM-location allows for a massive intercooler core
  58% larger than the OEM intercooler.
• Highly effective core design
  Bar-and-plate core with staggered and louvered fins.
• Smooth cast aluminum end tanks
  Engineered for low turbulence/restriction and maximum flow.
• No hidden labor costs or permanent modifications
  No trimming, cutting, or other modification required.

APR IC100017 Intercooler Design:

The APR Intercooler core is a large bar-and-plate design featuring densely packed staggered and louvered fins. This design offers exceptional cooling while balancing pressure loss across the core, and maintaining critical airflow to the components behind the intercooler system.

APRs Engineers paid close attention to the balance between core effectiveness and pressure drop through the core, core style and fin density. With fin density too low, pressure drop decreases dramatically, but typically results in a core incapable of effectively cooling. Likewise, with fin density too great, pressure drop increases dramatically, resulting in the turbocharger working harder, and hotter, to produce the same level of airflow. APRs Engineers were able to maximize performance by fine tuning this often unseen balancing act.

To fully utilize the massive core, APRs mechanical engineers designed cast aluminum end tanks organically shaped for proper airflow distribution across the entire core. The one-piece end tanks are CNC machined to provide a slip resistant mounting surface for hoses, precise integrated mounting surfaces, and perfectly flat connecting surfaces used for TIG welding the tanks to the core.

APR IC100017 Intercooler Manufacturing:
The APR Intercooler core is a large bar-and-plate design featuring densely packed staggered and louvered fins, cast aluminum end tanks are CNC finish machined before TIG welding the tanks to the core.

APR IC100017 Intercooler Install:
Installation of the APR intercooler takes about 4-6 hours. Basic hand tools and a Torx bit set are needed, installation involves removal of the bumper and headlights.
