Can anyone tell me if it is possible to fit an additional air filter to a 150 series Prado? How,etc?

An option would be to fit pre-cleaner or a filter "sock" to a snorkel.
There has been tests done which indicated the pre-cleaner only functioned at low speeds and was detrimental at road speeds though where as a sock works at all speeds and is easy to remove, clean and refit.
