If you own a Honda Civic with that peppy 1.5L turbo, you probably know it can struggle with heat-soak, especially if you’re still rocking the stock intercooler. Trust me, when the temperatures climb, you can kiss good power and efficiency goodbye. Spirited driving? Increased power? Yeah, you’re definitely going to feel those high charge air and cylinder temperatures creeping up. That’s where the PRL Motorsports intercooler upgrade comes into play.

This isn’t just some run-of-the-mill upgrade; we’re talking about a serious piece of hardware here. With a dense 25.5x4x6.3” bar-and-plate core rated for over 550 horsepower (and we’ve even pushed it to 600+ without breaking a sweat), this intercooler is designed to keep your charge air temperatures down and airflow up. Plus, the machined billet aluminum end tanks add that extra touch of durability and style.
