2023+ FL5 Honda Civic Type R

Drivers regularly see high oil temperatures completely stock and even higher on modified examples. In testing, CSF observed temperatures over 275°F (135°C) on the track, and it was clear the FL5 needed a solution. The engineering team set out to develop CSF's first ever complete engine oil cooler kit, and the results speak for themselves. CSF's new engine oil cooler kit is the "Real Deal" with stunning performance and an aggressive look to match.

Key Features:

• Two Dual Pass High-Performance Oil Coolers
• CPE lined stainless steel braided lines
• DYME Pro/Spec Quick Release Fittings
• Billet Sandwich Plate with 175-195°F (80-90°C) Thermostat
• Oil Temperature reduction of up to ~15°F (~8°C)
• Carbon Fiber Bumper Vents
• Laser cut mounting brackets
• Approximately 7 Quarts (6.6L) overall oil capacity
• Pair with theCSF 7221 FL5 Performance Radiator for maximum cooling performance

CSF spent over a year in testing and development of this kit working with R&D Partners and multiple drivers competing in Global Time Attack (GTA) and GridLife. Initial testing was performed in the controlled environment of a dyno. CSF then moved into aggressive real world testing and development on the track where most customers would be using these kits.

The 100% TIG welded construction with cast end tanks further increases the overall strength of the coolers. Every cooler is pressure tested to 120 PSI before leaving the factory so you can be confident you will never have one burst on you like some weaker designs used in other kits. The end tanks also feature specially designed 40-degree angle feed/return fittings for optimal flow and lower pressure drop.

Oil Cooler Key Features:

• Bar/Plate Core offers strength and durability
• 100% TIG Welded Construction tested to 120 PSI
• Smooth 40-degree feed/return fitting design
• Dual Pass flow for additional cooling
• Oil Capacity increased by over 2 Quarts (2 Liters)

When adding an engine oil cooler to a car that did not come with one from the factory, there is always a concern with pressure drop. This is due to the back pressure imposed on the system from running the oil through lines and cooling channels of an oil cooler.

In testing, CSF observed a small drop in oil pressure after installing the kit. While not a concern for casual driving, it was enough of an issue to address for those tracking their FL5s. To resolve this issue, CSF and test vehicles switched to a higher weight oil (from OE Spec 0W-20 to 0/5W-30) and this relieved the potential pressure issues.

CSF recommends the following oil weights depending on application:

• Light Track Duty and/or High Performance Street: 0/5W-30
• Heavy Track Duty and/or Dedicated Race Builds: 0/5W-40
