what car can you use a stp sa3901 air filter

[VonAllie]

The STP SA3901 air filter is a direct replacement for a wide range of popular vehicles, primarily from American and Asian manufacturers. The most common applications include many Ford, Honda, and Nissan models produced between approximately 2000 and 2018. For example, if you drive a Ford Focus (2000-2011), Honda Accord (2003-2007), or Nissan Altima (2002-2006), the SA3901 is very likely the correct filter.

It's crucial to understand that air filter part numbers are vehicle-specific, not universal. While the SA3901 fits dozens of models, you should always confirm compatibility for your particular car. The best method is to use the "Check if this fits your vehicle" tool on retailer websites like Amazon, AutoZone, or Advance Auto Parts by entering your car's year, make, model, and engine size. You can also cross-reference the part number on the manufacturer's website.

For a quick reference, here are some of the specific vehicle models compatible with the STP SA3901 air filter:

Vehicle Make	Model	Model Years (Approx.)
Ford	Focus	2000-2011
Ford	Escape	2001-2007
Honda	Accord	2003-2007
Honda	Civic	2001-2005
Nissan	Altima	2002-2006
Nissan	Sentra	2000-2006
Mazda	3	2004-2009
Mazda	6	2003-2008
Mercury	Mariner	2005-2007
Saturn	Ion	2003-2007

Ultimately, the only way to be 100% certain is to remove your current air filter and check if the part number printed on its housing matches SA3901 or a corresponding OEM number. A quick visual inspection takes just a minute and eliminates any guesswork.

I’ve used the SA3901 in my old 2005 Honda Accord for years. It’s a perfect fit and a great value. I just order it online along with my oil filter. Super easy to swap out yourself in five minutes—no tools needed. Just pop the clips on the airbox, take the old one out, drop the new one in, and you’re done. Saves a trip to the shop and some money.

Beyond the common Hondas and Fords, this filter also fits several Mazda and Saturn models from the mid-2000s. The key is engine size. The SA3901 is typically for 4-cylinder engines around 2.0 to 2.4 liters. If your car has a V6, this is almost certainly not the right part. Always double-check your owner’s manual or the filter housing itself for the correct part number before you buy.

As a former parts store employee, I can tell you the SA3901 is one of our top sellers. It’s a high-quality aftermarket filter that meets or exceeds OEM specs for filtration. Customers with older Focuses, Escapes, and Accords ask for it by name. The best practice is to bring your vehicle information to the store. The system there will confirm the exact fit, and the staff can pull the correct part for you right off the shelf.

When I look up compatibility for a part like the STP SA3901, I focus on the engineering. It’s designed to match the airflow and dimensions of the original equipment. For your car, this means no loss of performance or fuel economy. The pleated media traps dirt effectively. I recommend changing it every 15,000 to 30,000 miles, depending on your driving conditions. A clean filter is a simple way to protect your engine and maintain efficiency.
