Overview
The Fastrax 1/8th Exhaust Gas Cooler in blue is an essential performance accessory for anyone running a nitro-powered RC car in the UK and beyond. Whether you're a serious racer looking to gain competitive advantages or an enthusiast wanting to maximise your fuel efficiency, this purpose-built cooling system delivers measurable improvements to runtime and engine performance. The cooler is intelligently mounted between the tuned pipe and fuel tank, positioning it perfectly to intercept exhaust heat before it reaches your precious fuel supply. This thermal management approach is becoming increasingly recognised as a must-have addition for any serious racer seeking that extra edge on the track or during weekend bashing sessions.
Nitro RC cars generate tremendous heat during operation, and much of this thermal energy transfers directly to the fuel tank, warming the fuel and reducing engine efficiency. The Fastrax Exhaust Gas Cooler tackles this problem head-on by extracting thermal energy from the exhaust gases flowing from your tuned pipe. By lowering the temperature of the fuel before it enters the carburetor, you achieve multiple performance benefits: increased runtime from each tank of fuel, more consistent engine performance across longer sessions, and reduced thermal stress on your fuel system components. This makes it particularly valuable for competitive racing scenarios where every lap counts and fuel efficiency directly translates to more track time between refuelling stops.
Available in an attractive blue finish that coordinates with many popular RC car colour schemes, this cooler comes complete with mounting clip and fuel clips, providing everything needed for straightforward installation on 1/8th scale nitro RC vehicles. The included hardware ensures secure, reliable mounting without additional parts shopping, and the integrated fuel clips work seamlessly with standard fuel line sizes found on most 1/8th scale buggies, truggies and off-road racing vehicles across the UK RC hobby market.
Key Features
- Mounted between tuned pipe and fuel tank — The strategic positioning allows the cooler to extract maximum thermal energy from exhaust gases before heat can transfer to your fuel system, ensuring your fuel remains cooler throughout extended racing sessions and significantly improving overall engine efficiency.
- Reduces fuel temperature — By actively cooling the fuel supply, the cooler maintains more consistent fuel density and viscosity, which translates directly into more stable carburetor tuning and improved engine responsiveness across varying ambient conditions.
- Extends runtime — Cooler fuel burns more efficiently in your nitro engine, meaning you extract more usable power from each millilitre of fuel and enjoy noticeably extended running time between refuelling intervals, a critical advantage during competition or marathon bashing sessions.
- Includes mounting clip and fuel clips — The complete hardware package eliminates the need for sourcing additional components, providing secure attachment to your chassis and reliable fuel line connections that maintain proper flow while maximising heat transfer.
- Blue colour finish — The vibrant blue coating not only looks professional on your RC car but also provides protective anodising that guards against corrosion and thermal stress, maintaining appearance and durability through countless bashing sessions.
- Essential for serious racers — This component is recognised across the UK RC racing community as a performance upgrade that separates competitive setups from casual builds, making it invaluable for anyone pursuing consistent lap times and tournament success.
- 1/8th scale compatibility — Specifically engineered for 1/8th scale nitro vehicles, ensuring proper fitment and optimal thermal transfer rates across the full range of popular 1/8th buggies, truggies and competition off-road racing platforms.
Technical Performance
The Fastrax Exhaust Gas Cooler represents precision engineering focused on thermal management in nitro RC powerplants. Constructed with materials selected for their thermal conductivity and durability under extreme racing conditions, the cooler features an internal passage design that maximises contact between hot exhaust gases and the cooling chamber walls. The mounting system utilises aluminium construction where practical, providing excellent heat dissipation properties whilst maintaining lightweight characteristics essential for 1/8th scale vehicles. The included mounting clip secures the cooler to your chassis using standard hardware, whilst the fuel clips maintain consistent positioning of fuel lines through the cooler's internal passages. The cooler's design accommodates standard fuel line tubing dimensions found on virtually all 1/8th scale nitro vehicles, including popular platforms from Traxxas, HPI, Losi, Team Associated, Mugen and comparable manufacturers. Temperature reduction achieved through this cooler typically ranges from 5-15 degrees Celsius depending on ambient conditions and fuel flow rates, translating to measurable improvements in fuel consumption efficiency and engine performance stability. The blue anodised finish provides both aesthetic appeal and protective coating against the corrosive effects of nitromethane fuel and vibration-induced wear. Installation requires no modifications to existing fuel systems or engine components, making this an accessible upgrade for racers of all experience levels seeking immediate performance gains from their 1/8th scale nitro RC cars.

Frequently Asked Questions
- How much will the Fastrax Exhaust Gas Cooler improve my RC car's runtime? — Runtime improvements depend on several factors including ambient temperature, your specific engine tuning, driving style and ambient humidity levels. Most racers report noticeable improvements in fuel consumption efficiency ranging from 10-20%, effectively giving you several extra minutes of run time per tank. The cooler's primary benefit comes from maintaining optimal fuel temperature for carburetor tuning stability, which prevents the engine from running progressively richer as fuel temperature rises during extended sessions.
- Is this suitable for beginners or only serious racers? — Whilst the cooler is certainly valued by competitive racers and serious hobbyists, beginners can also benefit from improved runtime and more consistent engine performance. However, beginners should first develop competence with basic nitro engine tuning before adding accessories like this cooler. Once you understand carburetor adjustment and fuel management, adding a cooler makes tuning more predictable and rewarding.
- What size fuel lines does this cooler accommodate? — The cooler is designed for standard fuel line tubing dimensions used on virtually all 1/8th scale nitro RC vehicles across popular manufacturers. The included fuel clips provide secure positioning for typical 3-4mm diameter fuel tubing found on most 1/8th scale engines and fuel tanks.
- Will this cooler work on any 1/8th scale nitro RC car? — Yes, the Fastrax cooler is designed as a universal accessory for 1/8th scale nitro-powered vehicles. The mounting clip and fuel clips accommodate the standard chassis and fuel system layouts found on 1/8th buggies, truggies and competition vehicles. Installation requires basic familiarity with your vehicle's fuel system layout but does not require modifications.
- How do I install the exhaust gas cooler? — Installation involves positioning the cooler between your tuned pipe exit and fuel tank intake, securing the cooler using the mounting clip to attach it to your chassis, and routing fuel lines through the internal passages using the included fuel clips. Most installation can be completed in 10-15 minutes without special tools.
- What is the difference between this blue cooler and coolers in other colours? — The cooler is available in multiple colours including blue, with all variants featuring identical thermal performance and engineering. Colour selection is purely aesthetic, allowing you to match your RC car's colour scheme or personal preferences.
