Spoon Sports Low Temp Thermostat for Honda K20

The Spoon Sports Low Temp Thermostat 19301-DC5-000 is a performance cooling upgrade designed for Honda’s high-revving K20-powered Civic and Integra platforms.

Spoon Sports developed this thermostat with a lower opening temperature than the standard Honda thermostat. The Spoon unit begins opening at approximately 70°C and reaches its fully open position at approximately 82°C. By comparison, Spoon quotes the standard thermostat at approximately 78°C opening and 90°C fully open.

This means coolant can begin circulating through the radiator earlier, increasing the cooling system’s opportunity to reject heat before coolant temperatures climb further.

Why Fit a Low Temperature Thermostat?

During sustained high-RPM driving, track use or demanding performance driving, a modified K-series engine can generate considerably more heat than it would during ordinary road use.

The Spoon thermostat is designed to help manage this by opening earlier than the factory thermostat.

It does not increase the physical cooling capacity of the radiator by itself and should not be considered a cure for an overheating engine. Instead, it changes when coolant is directed through the radiator, making it a useful part of a properly maintained or upgraded cooling system.

For track-focused vehicles, it can be combined with other cooling upgrades such as a performance radiator, radiator hoses and suitable cooling-system maintenance.

Honda Civic Type R EP3 Application

For UK customers, the principal officially sold UK-market application is the 2001–2005 Honda Civic Type R EP3, powered by the 2.0-litre K20A2 i-VTEC engine.

The EP3 Type R was produced in Swindon and sold officially in the UK with the K20A2 engine. The Spoon thermostat is listed by Spoon for the EP3 chassis, while UK Honda performance specialists also sell part number 19301-DC5-000 specifically for the Civic Type R EP3.

Honda Integra Type R DC5 Compatibility

Spoon also officially lists DC5 Integra K20A compatibility for part number 19301-DC5-000.

The Honda Integra Type R DC5 was not officially sold as a UK-market Honda model. Examples found in Britain are predominantly Japanese-market imports. Therefore, it is intentionally not included in the strict UK-market fitment table below.

Owners of a UK-registered Japanese-import Integra Type R DC5 with the 2.0 K20A engine can nevertheless use this product where the vehicle remains compatible with the original DC5 cooling-system specification.

If your vehicle has undergone an engine conversion, thermostat housing conversion or other cooling-system modification, check compatibility before ordering.

Ideal For

This Spoon thermostat is particularly suitable for:

• Fast-road Honda Civic Type R EP3 builds
• Track-day EP3 applications
• K20 performance builds
• Turbocharged or supercharged applications where additional cooling management is required
• Honda Integra Type R DC5 Japanese imports
• Cars running upgraded radiators and cooling systems
• Replacement of an ageing thermostat when a performance alternative is desired

Important Fitting Information

The cooling system must be properly drained and refilled when replacing the thermostat.

Correct coolant bleeding is especially important on performance applications. Air trapped in the cooling system can cause unstable temperatures and overheating regardless of thermostat specification.

Always inspect the thermostat seal, hoses, radiator, radiator cap and coolant condition during installation.

Professional installation is recommended if you are unfamiliar with Honda K-series cooling systems.

6. Vehicle Fitment / Compatibility

Official UK-Market Vehicle

Honda Civic Type R EP3

• 2001–2005
• EP3 chassis
• 2.0-litre K20A2 i-VTEC
• UK-market Type R

Additional Verified Application – UK Registered Imports

Honda Integra Type R DC5
