Which K&N air filter will fit my Ferrari?

Some Ferrari owners like to add aftermarket air filters to their cars to increase air flow, and thereby increase performance. Owners of carbureted cars have commented that adding a high-flow air filter to their car makes the intake noise of the carburetor much more appealing. As with all aftermarket modifications, the choice is always yours to make, based on your personal preference.

Many Ferrari owners who use aftermarket filers choose K&N air filters. Unlike paper air filters, K&N filters are reusable. They require a special cleaning kit which contains an oil that is applied to the filters after cleaning to help them maintain peak airflow and filtration. Be sure to read the instructions that come with your air filter to ensure proper use.

Below are the appropriate part numbers of K&N air filters for various Ferrari models. K&N changed their part numbering system a few years ago, so both part numbers are listed, when available. Not all Ferrari filters are available in the US, however. The Availability column shows whether the filter is available through K&N Filters USA, K&N Filters Europe, or both. There is no difference between filters required for US and Euro version Ferraris.

K&N filters are available at most auto parts stores. If you are looking for a good mail order source for European version filters, try Kinnor Services in the UK.
