Volvo P2 R & T5 · OE-style dry media filter

The last filter your R will need.

Drops into the stock airbox and never needs oil. On a stock P2 R we measured +11 whp and +13 wtq from the filter swap alone.

SwedeSource filter with a blue powder-coated hexagonal aluminum cage

No oil

Dry synthetic media. Nothing to migrate onto your MAF sensor.

Aluminum cage

A hexagonal exoskeleton that keeps its shape under boost.

Washable

Blow it out with regulated air and put it back in.

Made in Illinois

Designed, built to order and shipped from the USA.

The cage

Boost tries to crush a filter.

Under boost, pressure across the filter is always trying to deform it. When the media collapses, it chokes off the airflow you paid for.

Every SwedeSource filter is built around a hexagonal aluminum exoskeleton instead of plastic or wire mesh. The cage holds its geometry however hard you push, so the media stays intact, protected and flowing as designed, whether you're commuting or maxing out the turbo.

It's modeled in SolidWorks to fit the factory airbox the way the original filter does.

The media · against the alternatives

Every other option is cotton.

There are three other performance filters sold for the P2 R airbox. All three are built on cotton, none of them has a structural cage, and none of them costs less than ours.

Why cotton is a problem

Cotton is the industry default because it's cheap and familiar. Over repeated oilings the weave stretches and opens inconsistent gaps, so it gets worse at filtering as it ages. On oiled filters that oil also migrates onto the MAF sensor and throws off your fuel trims.

Why a screen isn't a cage

A thin wire screen keeps the pleats in place on a shelf. It doesn't stop the filter deforming when boost is pulling on it. Our aluminum exoskeleton is the structure of the filter, and the media sits protected inside it.

SKU P2R · OE-style filter

P2 R / T5 filter

Sharper throttle tip-in, less turbo lag and a fatter torque curve, from a part that bolts into the airbox you already have.

Aluminum exoskeleton stops the filter collapsing under boost

Dry gradient-density media, no oiling and no MAF contamination

Cleans with a blast of 30–40 psi regulated air

Built to order in northern Illinois

How do I clean it?

Pull the filter and blow regulated air at 30–40 psi from the inside out. There's no wash kit, oil or drying time involved.

Warranty

One year, subject to approval. We replace your filter free the first time for manufacturing defects, rips or tears in the silicone that weren't caused by damage in use, or media defects we missed. Send the old unit back to get the replacement. One replacement per warranty period.

Returns

Full refund if your return is postmarked within 14 days of delivery. Outside that window, get in touch and we'll talk.

★★★★★

“It's a direct fit, the build quality is great and it flows well. Also matches the color scheme, which is a plus.”

What's next

Something bigger is building pressure.

SwedeSource started with one filter for one car. Since then we've been quietly engineering a full line of air induction parts for more turbocharged platforms, with the same aluminum exoskeleton and the same made-to-order care. It's getting a new name, too.

Feel the surge.

Who makes it

From CAD file to your mailbox.

No overseas factory and no outsourced quality control. Every filter is designed, built and shipped from northern Illinois, with as many parts as we can source in the US. They're made to order, and I pack each one at home and drop it off to ship myself.
