Opening the thermostat's valve at a lower temperature allows coolant to flow more freely during low-load sections of the racetrack. This enables the radiator to effectively regulate the engine's temperature within the optimal range during high-load sections. If a cooling system is pushed to its limits at the racetrack and overheating becomes an issue, a low-temperature thermostat can often resolve this problem. It achieves this by allowing the radiator to perform more cooling at lower engine loads, thereby preventing or delaying overheating during high-engine loads.\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThis part is made specifically for the Honda Civic Type-R FK8 \u0026amp; FL5 K20C1 versions. \n\u003cdiv\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); font-weight: var(--bs-body-font-weight); text-align: var(--bs-body-text-align);\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); font-weight: var(--bs-body-font-weight); text-align: var(--bs-body-text-align);\"\u003eLow-temperature thermostats offer several advantages and are useful in various situations.

Therefore, the paraffin wax shrinks, and a return spring pushes against the valve and plunger to return the thermostat to a partially open or closed position.  \n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe opening temperature of paraffin thermostats is primarily dependent on the spring rate of the return spring. The stiffer the spring, the greater the pressure the wax needs to generate to push the plunger. This wax chamber’s pressure is directly proportional to wax temperature.

The PWR aluminum radiator replaces your factory radiator with a high-flow aluminum core that cools way better. PWR makes three versions: Street Spec for daily driving and occasional track days, Weekend Warrior Spec for aggressive street driving and frequent track use, and Track Spec Triple Pass for dedicated track cars. All three use PWR's louvered R-fin and rolled dimple tube construction, which increases surface area and improves heat transfer compared to your factory radiator. Pick the version that matches how you're using your car.\u003c\/p\u003e\n\n\u003ch4\u003eHere's Why You Need a Better Radiator\u003c\/h4\u003e\n\n\u003cp\u003eYour factory radiator's adequate for street driving, but when you're at the track running back-to-back sessions, your coolant temps climb. High coolant temps mean your engine's making less power and you're getting closer to overheating. When your engine gets too hot, your ECU pulls timing and you lose power. If temps keep climbing, you're risking head gasket failure or warping your head. A better radiator increases your cooling capacity so your temps stay consistent even when you're pushing hard. You're maintaining consistent power output and you're not worrying about overheating between sessions.\u003c\/p\u003e\n\n\u003ch4\u003eStreet Spec - Single Pass for Daily Driving\u003c\/h4\u003e\n\n\u003cp\u003eThe Street Spec radiator's for daily drivers who do occasional autocross or track days. It's a single-pass design, which means coolant flows through the radiator once from inlet to outlet. Single-pass radiators flow more coolant volume, which makes them better for street driving. The Street Spec radiator cools way better than your factory radiator without being overkill for daily driving. If you're commuting to work every day and doing occasional spirited driving or autocross on weekends, this is what you need.\u003c\/p\u003e\n\n\u003ch4\u003eWeekend Warrior Spec - More Cooling for Aggressive Use\u003c\/h4\u003e\n\n\u003cp\u003eThe Weekend Warrior Spec radiator's for people who drive their car hard on weekends. It's got increased core efficiency and cooling volume compared to the Street Spec radiator. If you're doing frequent canyon runs, aggressive street driving, or regular track days, the Weekend Warrior handles repeated hard pulls and sustained high-speed driving better than the Street Spec. It's still totally streetable for daily driving, but it's got more cooling capacity when you're pushing hard.\u003c\/p\u003e\n\n\u003ch4\u003eTrack Spec Triple Pass - Maximum Cooling for Dedicated Track Cars\u003c\/h4\u003e\n\n\u003cp\u003eThe Track Spec Triple Pass radiator's PWR's most aggressive radiator. It's designed for serious track use where you're doing HPDE, time attack, or endurance racing. The triple-pass design forces coolant to flow through the radiator three times before exiting, which increases coolant residence time and maximizes heat rejection. Coolant enters the radiator, flows through the core from one end to the other, loops back through the core a second time, then loops back through a third time before exiting. You're maintaining consistent coolant temps even during long track sessions in hot weather. This radiator's for dedicated track cars. If you're daily driving your car, get the Street Spec or Weekend Warrior instead.\u003c\/p\u003e\n\n\u003ch4\u003eLouvered R-Fin and Rolled Dimple Tube Core\u003c\/h4\u003e\n\n\u003cp\u003eAll three PWR radiators use louvered R-fin and rolled dimple tube construction. The louvered fins increase surface area, which means more air contact and better heat transfer. The rolled dimple tubes create turbulence in the coolant flow, which improves heat transfer from the coolant to the tubes. You're getting way more efficient cooling than your factory radiator's flat tube design. More surface area and better coolant flow mean lower temps under the same conditions.\u003c\/p\u003e\n\n\u003ch4\u003eDirect Bolt-In Replacement\u003c\/h4\u003e\n\n\u003cp\u003eAll three PWR radiators are direct replacements for your factory radiator. You unbolt your factory radiator, bolt the PWR radiator in using your factory mounting points, connect your hoses, and you're done. You're not modifying your radiator mounts or your fan shroud.
