$375-$400 to upgrade Filter?

[Blessed 1]

Went to the dealer today to purchace a Heavy Duty air filter for my Lazer Z Hp 18 hp expecting to spend about $200. I was informed that in order to convert it over I have to buy a new Carb as well which adds another $175. For $375 to upgrade to a heavy duty air filter I think I am just going to have to stick with that old style. Are there any other options to consider?

Blessed1,

Some of the Kohlers just like some of the Kawi's require a replacement carburator while other only require a change to the jets. I am not aware of any other filter options other than the OEM filters that are available.
