TWIN AIR
Twin Air built its name on air filtration. The dual-foam filter and pre-oiled service kits are workshop standards — fit, seal, breathe, done. Filters trap dust before it scores your bore; cages and backfire screens go in with them. Service intervals stay short when you ride dusty. Pick the filter for your make and model, grab the oil and cleaner, and keep the top end alive.

Common questions, straight answers. No fluff.
- These filters cover almost every modern enduro and motocross machine. The dual-stage foam is designed specifically for off-road environments. It handles the dust of a dry track and the mud of a British winter with equal efficiency.
- Pre-oiled options save significant time in the paddock. The oil is applied mechanically to ensure total coverage without any dry spots. This consistency is difficult to achieve by hand in a rush. If you are racing back-to-back heats or a long-distance hare and hound, having a sealed, ready-to-use filter in your kit bag is essential. It prevents dirt ingress from the moment you drop it into the airbox. You avoid the mess of manual oiling and ensure the foam density is not compromised by over-saturation.
- Standard cages work for most riders. High-flow versions remove the restrictive backfire screen to increase air intake. This is a common modification for closed-course racing where every fraction of throttle response matters. Check if your bike requires a specific seal for the screenless setup.
- These parts are designed to match the dimensions of your factory airbox exactly. They use a thick, flat foam sealing ring to ensure a leak-proof fit against the intake tract.
- Verify your bike's year and displacement. Manufacturers often change airbox shapes between generations, even if the plastics look similar. Look at the mounting point on your current cage. Some use a central bolt while others use a clip system. Ensure the filter you select matches this interface. If you have an aftermarket intake system, the standard filter might not fit. Always measure the diameter of the cage if you are running a non-standard setup. This prevents air leaks that could lead to a top-end failure during your next ride.
- The dual-layer design is ideal for fine silt and sand. The outer layer stops the heavy particles while the inner layer traps the microscopic dust. For extreme conditions, consider adding a dust cover over the main element for an extra layer of protection.
