Installing an Injen Intercooler is an quick way to drastically increase the cooling power of your factory intercooler system. Injen intercoolers are drop-in (bolt-on) replacements for your factory intercooler, so no cutting or welding is needed. The installation is easy and the cooling and power benefits are real. Why would an intercooler add power? The simple reason is that colder air makes more power. This is because cold air is denser and has more oxygen (per unit volume), and it helps keep the engine cylinder air charge cooler as well (resulting in better reliability under spirited driving conditions). Intercooler upgrades like this Injen one perform even better as your Honda Civic picks up speed, since more fresh cold air is constantly being pushed through it!

Key Features:

• Easy drop-in (bolt-on) installation.
• Significantly reduces the temperature of the air entering into your engine, resulting in more power and also better reliability under spirited driving conditions.
• Increase throttle response and decreases turbo lag.
• Constructed with cast end tanks and precision CNC-machined aluminum flanges.
• Minimal boost pressure drop.
• TIG-welded and has a slick silver finish.
