air filter maintenance

I've never heard of these filters and need to replace mine on an '94 ls400. Where do you get them and how much?

I don't think that 94 LS 400's were equipped with cabin air filters, although they were equipped with engine air filters.

if this is an after market engine air filter then you wash with a special detergent, then wet with a special oil.

seems like a lot of work compared with a stock air filter
