Technical Notes:

It’s no secret that Honda’s 1.5L turbo Civic is extremely susceptible to heat-soak, especially when retaining the factory intercooler. Excessive heat-soak increases the risk of detonation and causes major power-loss due to high charge air and cylinder temperatures. These issues become even more prevalent with spirited driving and/or increased power outputs. The PRL Motorsports intercooler upgrade decreases charge air temperatures while increasing potential airflow with its dense 550+ horsepower rated (though we have pushed 600+) 25.5x4x6.3” bar-and-plate bar-and-plate core and machined billet aluminum end tanks! This intercooler utilizes factory mounting spots with our embossed end tanks. Kits will come with all hardware needed for a seamless install.

Performance Gains:

• 9 horsepower & 3 ft/lb torque gains by simply bolting on
• 50+ F degree drop in post charge air temperature at peak
• Average of 36 F degree drop in post charge air temperature
• Increased efficiency & consistency in power delivery
• Increased engine safety

Kit Includes:

• (1) Intercooler Assembly w/ Billet End Tanks
• (2) Air Guides w/ Stainless Hardware
• (2) Billet Aluminum Factory Charge Pipe Adapters
• (1) Cardboard Stencil w/ “PRL” Logo
• (2) PRL Factory Style Replacement O-Rings
