Spy Racing F1 250cc & 350cc Air Filter (Service Part)
Replacement service air filter suitable for Spy Racing F1 and F3 quad bikes. Designed to replace worn or damaged air filters and help maintain optimum engine performance by providing clean airflow to the carburettor.
Please check the inside diameter of your existing air filter before ordering. Spy Racing quads have been fitted with different carburettors over the years, so the correct filter size must be matched to your current setup.
Available sizes:
* 44 mm
* 48 mm
* 50 mm
As a general guide:
* 48 mm filters are most commonly fitted to Spy Racing F1 250cc models.
* 50 mm filters are most commonly fitted to Spy Racing F1 350cc models.
Please note: These sizes are a guide only. We strongly recommend measuring the inside diameter of your existing filter or the carburettor inlet before ordering, as previous owners may have fitted a different carburettor.
If you’re unsure which filter you need, feel free to contact us with a photo of your current setup and we’ll be happy to help.
