89mm. K&N sports air filter with great effect

This filter is a CLAMP-ON air filter, ie it can be clamped on a round tube that is 89mm. in outer diameter. Since the material it covers is made of rubber, it can extend well beyond the 89mm.

You can advantageously buy a K&N filter cleaning kit - Gives your air filter a longer life and keeps the effect up.
