Overview
The Fastrax 1/8th Exhaust Gas Cooler Red w/Mounts is an essential performance upgrade for serious RC nitro racers across the UK who demand maximum runtime and consistent fuel temperatures. This innovative cooling system is specifically engineered to work with 1/8th scale nitro-powered RC cars, intercepting hot exhaust gases before they enter your fuel tank and dramatically reducing fuel temperature. By lowering the temperature of the fuel circulating through your RC car's engine, this exhaust gas cooler directly extends your runtime on a single tank, giving you more track time and better performance during critical races. Whether you're competing in off-road racing or simply want to maximise the efficiency of your nitro-powered RC vehicle, this is a must-have addition that separates serious competitors from casual bashers.
Available in eye-catching red and supplied with additional mounting clips and fuel clips, the Fastrax exhaust gas cooler is engineered to integrate seamlessly into your existing RC setup without requiring major modifications. The clever mounting design positions the cooler between your tuned pipe and fuel tank, allowing the aluminium construction to absorb excess heat from the exhaust stream. This passive cooling approach requires no power source or complex wiring, making it one of the most straightforward performance upgrades you can add to any 1/8th scale nitro RC buggy, truggy, or off-road racer.
RC enthusiasts across the UK have discovered that fuel temperature management is critical for consistent performance, especially during extended racing sessions or competitive events where every second counts. The temperature differential between hot and cold fuel can affect engine tuning, fuel atomisation, and overall power delivery. By investing in the Fastrax exhaust gas cooler, you're taking control of one of the most overlooked variables in nitro RC performance tuning.
Key Features
- Heat Interception System — The cooler mounts directly between your tuned pipe and fuel tank, positioning it perfectly to intercept hot exhaust gases before they transfer heat into your fuel supply, which is the most effective location for maximum thermal efficiency on any 1/8th scale RC car.
- Aluminium Construction — Built from aluminium which naturally absorbs and dissipates heat effectively, the robust construction ensures durability through season after season of competitive racing without degradation or corrosion.
- Extended Runtime — By maintaining lower fuel temperatures, the cooler allows your engine to produce more consistent power throughout your fuel load, effectively extending your total running time and giving you more laps per tank than without cooling.
- Included Mounting Hardware — Comes supplied with additional mounting clips and fuel clips so you have everything needed for straightforward installation on your 1/8th scale RC vehicle without hunting for aftermarket bracket solutions.
- Multiple Colour Options — Available in a selection of colours including red, orange, and blue, allowing you to match your RC car's aesthetic whilst benefiting from identical performance advantages across all colour variants.
- Passive Cooling Technology — Requires no electrical power, sensors, or complex wiring to operate, making it a completely passive system that works whenever your engine runs without adding weight to your power system or drawing current from your battery.
- Competitive Racing Essential — Specifically designed for serious racers who understand that fuel temperature consistency is a professional-level tuning variable that separates winners from mid-pack runners in competitive RC racing environments.
- Easy Installation — The compact design with integrated mounting points makes fitting straightforward on most 1/8th scale RC vehicles, whether you're running a buggy, truggy, or off-road truck platform.
Technical Performance
The Fastrax 1/8th Exhaust Gas Cooler demonstrates the engineering philosophy that serious RC performance isn't always about bigger motors or more power — sometimes it's about controlling the variables that affect power delivery and consistency. The aluminium body acts as a heat sink, absorbing thermal energy from the exhaust gases that pass through the connecting pipes on their way to the fuel tank. This clever thermal management approach means that fuel entering your engine's fuel pump remains cooler than it would be without the cooler in place, resulting in denser fuel mixture and more consistent combustion characteristics throughout your fuel load. For 1/8th scale nitro RC cars, this translates to more predictable engine behaviour, easier tuning, and the ability to extract maximum performance during critical race moments. The additional mounting clips and fuel clips supplied with the cooler ensure secure installation that won't vibrate loose or shift during high-speed running or aggressive cornering. User feedback from the RC community confirms that positioning is crucial for maximum effectiveness — placing the cooler near front body vents where it can benefit from airflow provides superior results compared to mounting above the exhaust pipe where it would absorb additional heat. The build quality reflects Fastrax's reputation for producing reliable performance parts that withstand the demands of competitive racing without failure or degradation.

Frequently Asked Questions
- Will an exhaust gas cooler really improve my 1/8th scale RC car's performance? — Yes, by reducing fuel temperature before it enters the tank, the cooler helps maintain more consistent fuel density and engine characteristics throughout your fuel load. Many UK RC racers report noticeable improvements in runtime and throttle response, though the degree of improvement depends on ambient temperature and track conditions. Some users have reported runtime increases of up to 2,600 laps worth of extended track time, whilst others note the benefit is primarily in consistency rather than dramatic performance gains.
- How much runtime improvement can I expect from this cooler? — Runtime improvements vary depending on track temperature, ambient conditions, and engine tuning, but the primary benefit is fuel temperature consistency rather than outright duration increase. The cooler allows your fuel to remain at a lower and more stable temperature, which means more consistent engine performance rather than power dropping as fuel heats up during extended runs.
- Where should I mount the exhaust gas cooler on my RC car? — The cooler performs best when positioned to benefit from air circulation, such as near front body vents where moving air can help dissipate heat. Positioning it above the exhaust pipe only causes it to absorb additional heat rather than cool fuel, so strategic placement for airflow is important for maximum effectiveness.
- Is installation complicated? — No, the Fastrax exhaust gas cooler is designed for straightforward installation between your tuned pipe and fuel tank. With the supplied mounting clips and fuel clips included, fitting is accessible for most RC enthusiasts with basic mechanical skills and standard RC tools.
- Will this work on any 1/8th scale nitro RC car? — Yes, the cooler is designed as a universal fit component for 1/8th scale nitro vehicles. The included mounting hardware provides flexibility for installation on buggies, truggies, and off-road RC trucks, though you may need to adapt mounting depending on your specific chassis layout.
- Does the cooler add significant weight to my RC car? — The aluminium construction keeps weight minimal, and the performance benefits from improved fuel consistency typically outweigh any minor weight addition, especially for racing applications where every fraction of a second matters.
- Is this suitable for beginners? — Whilst the cooler is straightforward to install, it's primarily designed for serious racers who understand nitro engine tuning and want to optimise every variable. Beginners may find other upgrades more immediately beneficial, though there's no downside to adding a cooler to any nitro RC setup.
