Fastrax 1/10th Air Filter Re-Buildable Blue FAST851B

Overview

The Fastrax 1/10th Air Filter Re-Buildable in Blue (FAST851B) is an essential upgrade for any RC enthusiast running a 1/10th scale nitro-powered RC car. Whether you're a seasoned competitor looking to fine-tune your engine performance or a weekend basher who wants to keep their RC vehicle running at peak efficiency, this re-buildable air filter offers exceptional value and reliability. The bright blue colour makes it easy to identify and adds a splash of colour to your RC setup, whilst the re-buildable design ensures you can maintain and service your filter multiple times over, making it one of the most cost-effective air filter solutions available in the UK RC market.

Air filtration is absolutely critical for any nitro-powered RC car. Dust, dirt and debris can rapidly degrade engine performance, reduce reliability and lead to costly repairs. The Fastrax re-buildable air filter protects your expensive engine investment by trapping contaminants before they reach the fuel system and combustion chamber. This genuine Fastrax component is designed to work seamlessly with 1/10th scale nitro buggies, trucks and other vehicles that use standard air intake systems. With its proven track record and affordable price point, it's the go-to choice for RC enthusiasts across the UK who demand quality without unnecessary expense.

What sets this filter apart is its true re-buildable construction. Rather than throwing away used filters after a few running sessions, you can simply clean, service and rebuild this filter using new sponge elements and filter oil. This makes it perfect for regular racers, club members and anyone who wants to minimise maintenance costs whilst maintaining the highest air intake quality for their RC engine.

Key Features

• Re-buildable Design — This air filter features a robust re-buildable construction that allows you to service and maintain it repeatedly throughout its lifespan, saving you money compared to disposable filter alternatives and reducing waste over time.
• Includes Filter Oil — The package comes complete with filter oil, which is essential for optimal filter performance as it helps trap smaller dust particles and maintains proper air flow characteristics for your engine.
• Includes Mount Hardware — Everything you need to install the filter on your RC car is included in the box, with mounting hardware supplied so you can get running immediately without purchasing additional components.
• 90-Degree Adapter Included — The included 90-degree adapter provides flexibility in how you mount the filter on your vehicle, allowing you to position it optimally for your specific chassis layout and air intake configuration.
• 1/10th Scale Specification — This filter is precisely engineered for 1/10th scale RC cars, ensuring perfect fit and compatibility with standard nitro engine carburettor setups found on popular UK RC brands including Traxxas, Losi, HPI, OFNA and similar manufacturers.
• Bright Blue Colour — The distinctive blue finish makes your filter easy to identify and adds visual appeal to your RC car whilst helping you quickly spot it during maintenance or troubleshooting sessions.
• Genuine Fastrax Quality — Fastrax is a recognised and trusted manufacturer of RC aftermarket parts, and this filter represents years of engineering experience and reliability that RC enthusiasts have come to expect.

Technical Performance

This re-buildable air filter is engineered with careful attention to both air flow characteristics and filtration efficiency. The foam sponge element construction provides an excellent balance between protecting your engine from harmful contaminants whilst maintaining the air flow rate your nitro engine requires for optimal performance. The filter's design ensures minimal restriction at the intake, allowing your engine to receive clean, unrestricted air at full throttle. Built with durable materials throughout, the re-buildable housing is designed to survive countless rebuild cycles without degradation. The included filter oil works in conjunction with the foam element to create multiple layers of protection — the oil-saturated sponge catches larger particles whilst the oil itself captures finer dust that might otherwise pass through. For 1/10th scale nitro vehicles running standard carburettor setups, this filter delivers the performance characteristics needed for competitive racing and recreational bashing alike. The 90-degree adapter included provides installation versatility across different RC car chassis designs, making this a genuinely universal solution for 1/10th scale nitro enthusiasts across the UK RC hobby scene.

What's in the Box

Frequently Asked Questions

• What do I need to do to rebuild this air filter? — Rebuilding this Fastrax filter is straightforward and affordable. Simply remove the filter from your car, carefully extract the used foam sponge element, clean the housing thoroughly, install a new sponge element (available separately as the Fastrax 1/10th Air Filter Re-Buildable Double Sponge kit), saturate it with the included filter oil, and reinstall on your vehicle. This process takes just minutes and costs far less than purchasing new filters repeatedly.
• Is this suitable for all 1/10th scale nitro RC cars? — This re-buildable air filter is designed for standard 1/10th scale nitro engines with conventional carburettor setups. It is compatible with most major brands used in the UK including Traxxas nitro vehicles, Losi cars, HPI models, and similar 1/10th nitro platforms. However, if your vehicle uses a non-standard intake configuration, we recommend checking compatibility before ordering.
• How often should I service this air filter? — For regular use, we recommend servicing your air filter every 3-4 running sessions or whenever you notice a visible reduction in engine performance. If you run frequently in dusty conditions, more frequent servicing may be beneficial. The beauty of this re-buildable design is that servicing is quick, easy and affordable.
• What is the difference between this filter and disposable alternatives? — The key advantage of this re-buildable filter is long-term value and environmental responsibility. Whilst disposable filters must be replaced constantly, this Fastrax filter can be rebuilt multiple times using replacement sponge elements. Over a season of regular RC running, you'll save significant money whilst also reducing the waste associated with single-use filters.
• Do I need any special tools to maintain this filter? — No special tools are required. You can service this filter using basic items you likely already have — running water to rinse the housing, the included filter oil, and replacement sponge elements. The re-buildable design prioritises ease of maintenance for all skill levels.
• Where can I buy replacement sponge elements for this filter? — Fastrax produces the Fastrax 1/10th Air Filter Re-Buildable Double Sponge kit (which includes two replacement foam elements) as a direct replacement. RC Model Shop stocks this item and other Fastrax filter accessories, so you can keep your filter performing perfectly throughout the season.
