WOT Spec PWR Triple Pass Radiator Optional Transmission Cooler

Built to conquer the heat and keep your Type R running strong lap after lap, the WOT Spec PWR Triple Pass Radiator is the ultimate cooling solution for the FL5 and FK8 platforms. Developed in partnership with PWR and tested under grueling real-world conditions, this radiator proved its worth on a 101°F track day — delivering stable coolant temps and consistent lap times where others fell short.

Unlike typical radiators, this triple pass unit is engineered for absolute thermal efficiency. During torture testing, coolant temperatures remained rock solid — even after 30 minutes of continuous lapping in triple-digit ambient temperatures. When compared directly to another Type R equipped with a PWR single-pass track spec radiator, the WOT triple pass showed a 14°F lower coolant temperature after multiple laps at pace. That difference only grows over extended sessions.

In the final and hottest session of the day (101°F ambient), this radiator supported continuous lapping for 30 minutes straight at an average 2:01.9 pace — outperforming every other FK8/FL5 present. Coolant temps stayed consistent between 228°F–233°F, proving the system's endurance race readiness.

Key Features:

• Exclusive WOT Spec triple pass design by PWR

• Integrated transmission cooler

• Direct bolt-in fitment for FL5 Civic Type R – no cutting or modifications required

• Proven on track in 100°F+ ambient temps

If you're serious about cooling performance and want a track-proven solution trusted at the limit, this is the setup for you.
