Easy to install. Hopefully it will be more cost effective in the long run.

I used this filter as a special Air Cleaner replacement for a 1955 Ford Thunderbird that otherwise would normally have an Oil Bath air cleaner. There is a company that makes air filter cleaner replacements for the old Oil Bath cleaners and I upgraded the included air filter to a K&N Filter, and I am happy with the results. For anyone else that has a 1955 or 1956 Ford Thunderbird with the original Oil Bath cleaner, you can upgrade to an air filter cleaner assembly from (Brand Name) and then upgrade the air filter to a K&N. Hope this helps any fellow '55-'56 T-Bird owners.
