The TE37 redefined what a sports wheel could be. Ultra lightweight, highly rigid, and race-proven across streets and circuits worldwide.
The “TE” in the name comes from Touring Evolution, and “37” represents the remarkable weight of around 3.7kgs, unheard of for a 15 inch wheel at the time. Since then, the TE37 has remained true to its purpose as an ever-evolving forged wheel.
The 30th Anniversary series carries on that enduring philosophy, while applying the latest manufacturing and analysis technologies. Based on the TE37 Saga S-Plus, TE37 Sonic, and TE37 Ultra Large P.C.D., it is crafted as an homage to the original TE37.
Two versions to choose from: Machining or Sticker
Machining – Features a specially machined logo commemorating the 30 years of RAYS’ innovation and challenge.
Sticker – Bronze wheels are finished with a black sticker, while white wheels feature a blue sticker, details inspired by the first generation model TE37.

It didn’t take long for the FL5 Civic Type R to start hitting the track and being involved in a variety of racing series in large numbers. The car comes from the factory tuned for incredible handling and ample power to keep up with plenty of production sports cars. However, there is one area the Honda engineering team came up short, and that was the oil cooling system.
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.
Design & Engineering
The initial challenge when designing this engine oil cooler kit was two fold. Firstly, the K20C1 did not come with any type of external engine oil cooler provision. The second challenge was space in which to mount an external engine oil cooler(s). The front bumper opening already has the Intercooler, A/C Condenser, and Radiator stacked there and using most of the available air.
While mounting an additional cooler behind the grill is the simple option, that just adds more heat to the full system and takes away from the cooling capacity of the radiator. On top of that, most owners who track their cars will have an upgraded/larger intercooler which further compounds the issue. That means the sides of the bumper are the obvious and optimal placement. However, the FL5 does not have great airflow in that area. To improve airflow, CSF needed to design a ducting/inlet system that would allow proper airflow for optimal performance.
With proper airflow handled, CSF built the kit around our compact universal oil coolers (CSF #8119), using two of them to offer the greatest cooling capacity possible. Paired with Superstrasse CPE lined stainless steel braided lines and DYME Pro/Spec Quick Release Fittings, this kit is the most serviceable kit on the market.
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
The CSF kit is built around two 13” x 4.5” (33cm x 11.5cm) Dual-Pass Oil Coolers (CSF #8119) run in series. These High-Performance Coolers offer maximum heat dissipation with uncompromising durability. The Bar/Plate cores feature CSF’s “Aero-Flow” Bar Design which reduces weight while offering impressive strength and flow. The rugged design of these cores means you won’t need to worry about debris from the track puncturing the coolers like with tube and fin cores.
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.

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)
The are the same coolers Honda Racing Corporation (HRC formerly HPD) uses on Honda’s factory FK8 TCR Touring Car. Honda and many racing teams/drivers saw a lot of success with the FK8 Type R TC. CSF is already working with teams like Precision Racing LA for their FL5 Touring Race Car and in talks with other SRO teams and HRC themselves.
Pressure Drop
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.

Ducting & Vents
The challenge of getting proper air flow to the oil coolers was straightforward but far from simple. While mounting an additional cooler behind the grill would be the easy choice, that just adds more heat to the rest of the cooling system. The optimal placement for the coolers was in the sides of the bumper outside of having no direct airflow. While technically some air does flow to this area as it leaks around the intercooler, it is not enough for significant cooling performance. While utilizing the brake cooling ducts is a potential option, that could negatively impact braking performance.
CSF designed and modeled vents for the bumper to provide the two oil coolers with ample airflow to keep engine oil temperatures in check. These vents were carefully designed with CFD software for airflow and aero dynamics. Made from pre-preg carbon fiber, these vents match the lines and style of the FL5 and give a very OEM+ look to the front bumper. To further improve airflow and cooling, the kit also includes louvered vents that allow airflow out of the bumper area and into the fender wells.
OE Fit and Finish
CSF leveraged many industry connections to find the best possible source for motorsport grade carbon fiber. The quality, fit, and finish of these parts are of the highest caliber and have been extensively track tested. Each vent bolts on without the use of double sided tape so they are very secure.
Cut out templates are included with the kit instructions to allow for easy installation and ensure proper alignment. CSF also designed templates for the international market with FL5s that come equipped with PDC sensors. The factory PDC sensors will still function perfectly and retain the OE look and feel.
While there may be kits available that do not require cutting the bumper, they cannot match the airflow and cooling performance of the CSF kit.
Air Duct Key Features:
Motorsport Grade Pre-Preg 2×2 Carbon Fiber Construction
OE level fitment and finish*
Provides optimal airflow to the Oil Coolers vs kits with air deflectors from the center opening
Instruction include cut out templates for easy install with motorsport grade hardware (no tape)
Laser Cut Louvered Vents for airflow into the wheel wells
*Note: Carbon fiber vents can be refinished as in matte clear or painted. CSF recommends using a qualified paint or body shop for best results.
Testing and Results
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.
Dyno Testing
For initial testing, CSF turned to the automotive authorities and industry experts at MotoIQ for third party verified data collection. Mike and the team there developed the testing procedures for the prototype baseline data.
Temperature readings were taken with two temperature sensors installed at the oil filter housing/sandwich plate for the most accurate readings. The FL5 was first run for 9 consecutive pulls on the dyno at World Motorsport to simulate hard driving and engine oil heat soak. The prototype CSF Oil Cooler Kit was then installed and the same test was conducted again. Average ambient temperature was only 0.5°F (0.3°C) higher on the test with the CSF kit.
You can see from the results the CSF prototype kit offered consistently cooler engine oil temperatures throughout the test. On average the engine oil temperatures were about 9°F (5°C) cooler with the CSF kit installed. While the max temperature seen was only 222°F (105.5°C), this gave the engineering team a great comparison data point. This test was performed before the addition of the fender liner vents.
While the dyno is a great place to begin testing, the track test results reveal dramatic reductions in engine oil cooler temperatures under extreme conditions.
