PRL Motorsports Red Baffled Coolant Expansion Tank Acura Integra Type S | Honda Civic | Civic Type R 2016+
$335.99

If you’ve been around the Honda or Acura scene for a while, you know those factory plastic coolant expansion tanks can be a bit of a weak link. Over time, they just can’t handle the heat and pressure, and that’s where the PRL Coolant Expansion Tank kit comes into play. This isn’t just a replacement; it’s an upgrade. Made from tough 6061 aluminum, this tank is built to last. Unlike the stock plastic piece, it won’t crack or warp under pressure, and it can handle higher temperatures without breaking a sweat.

One of the standout features is the increased capacity. The PRL tank holds a solid 1.32 quarts (that’s about 1.25 liters) of coolant, which is more than double what the factory tank can manage at just .58 quarts (or .55 liters). More coolant means better heat dissipation from your engine, which is crucial for performance, especially if you’re pushing your ride hard. Plus, it keeps your engine bay looking neat and tidy—no one wants a cluttered mess under the hood.

What’s really cool about this tank is its construction. It’s made from 3mm thick aluminum and features internal baffling to prevent coolant sloshing and cavitation, which can mess with your engine’s performance. And let’s not forget about the finish. You can choose between a striking red or black anodized look, both with laser-engraved logos that add a touch of flair to your setup.

The kit comes with everything you need to get it installed on your FK8, FL5, or DE5 Civic Type-R or Integra Type-S. It includes all the necessary fittings, like billet machined barb fittings and a sight glass for monitoring coolant levels. Plus, the Buna-N O-rings provide excellent temperature and leak resistance, so you can drive with confidence.

Features:

  • Sturdy 3mm 6061 Aluminum Construction
  • Laser Cut and TIG Welded for a Perfect Fit
  • Available in Eye-Catching Red or Black Anodized Finish
  • Includes Billet Machined Barb Fittings and a Sight Glass
  • Durable Buna-N O-Rings for Leak Resistance

What’s in the Box:

  • Fully welded and anodized expansion tank (choose red or black)
  • 1x 1/16" NPT 8mm barb fitting
  • 2x 8AN ORB 14mm barb fittings
  • 1x 8AN ORB 17mm barb fitting
  • 1x 8AN ORB 8mm barb fitting
  • 1x 10AN sight glass

Compatibility:

  • Honda Civic Type R 2.0L Turbo FK8 | FL5 (2017-2025)
  • Acura Integra Type S 2.0L Turbo (2024+)
  • Honda Civic 1.5L Turbo (2016-2021)

So, if you’re looking to boost your cooling system’s reliability and performance, the PRL Coolant Expansion Tank is worth considering. It’s a solid piece of gear that not only performs well but also looks great under the hood.
