Subaru STI Air Cleaner Element Performance Parts Information serving San Francisco, CA

Improve Performance & Efficiency with an STI Air Cleaner Element from Carlsen Subaru Serving San Francisco, CA

Bring more engine performance to your Subaru with our STI air cleaner element available in Redwood City, CA

When it comes to getting the most from the turbocharged BOXER® engine in your Subaru WRX, more air is better. The factory air filter is fine for basic driving around, but even if you only take your WRX for the daily drive and errands around town, upgrading to a genuine STI performance air filter element offers a range of benefits. This is a drop-in replacement for the factory engine air filter, and its paper element with steel mesh construction doesn't need oiling like other performance air filters.

What are Some Advantages of an STI Air Cleaner Element in Your Subaru WRX?

At the heart of this STI performance upgrade is a higher flow of clean air through the Subaru BOXER® engine intake. This higher volume of air allows for greater combustion which means you can enjoy more power and better efficiency. Since Subaru WRX models are equipped with a turbocharger, this means you can enjoy a quicker throttle response while each power stroke of the piston makes better use of fuel.
