To find out which engine a Fram air filter CA8221 fits, I recommend:
* Checking the Fram website: They usually have a search function or a compatibility guide that you can use to find the right filter for your engine.
* Looking at the packaging: The air filter packaging usually lists the compatible vehicles or engines.
* Consulting a parts store or mechanic: They can help you find the correct air filter for your specific engine.
Please note that air filter compatibility can vary depending on the year, make, and model of the vehicle, so it's important to be as specific as possible when searching for information.
