The K&N 33-2388 is a panel-style replacement engine air filter for the 4.4-liter V8 in the Volvo S80. K&N's washable, reusable High-Flow Air Filters use layered, oiled cotton media that the manufacturer says is meant to improve airflow while capturing contaminants. Compared with a disposable paper element, this filter is built to be cleaned, re-oiled, and reinstalled over the life of the car, so you aren't buying a new filter at every service interval.
The purchase case rests on the manufacturer's stated performance goal and long service life. The manufacturer positions the filter as designed to increase horsepower and acceleration, and its construction is meant to be durable enough to last for the entire lifespan of your vehicle. Warranty terms are described differently across sources, so confirm current coverage with K&N before you buy. The part is aimed at owners of the 2007 S80 V8 who want a reusable, high-flow upgrade over the stock paper element.
Fitment is the first thing to verify. The manufacturer lists this filter for the VOLVO S80 V8-4.4L F/I, 2007-2010 application. Installation is straightforward because the filter is designed to install easily into your factory air box, and it arrives pre-oiled. Keep the 1.9 oz (56 ml) re-oiling amount in mind when you clean it, and search for terms like "Volvo S80 4.4 V8 reusable air filter," "drop-in cotton gauze air filter," and "S80 V8 high-flow intake filter" when comparing options.
The manufacturer lists this filter for the Volvo S80 V8-4.4L F/I for 2007 through 2010. Fitment details differ across sources, so confirm your exact year, engine, and VIN with K&N before ordering.
Yes. The manufacturer states the filter is pre-oiled and ready to drop into the factory air box. If you clean and re-oil it later, the manufacturer's stated re-oiling amount is 1.9 oz.
The manufacturer states the filter needs cleaning about every 75,000 miles under normal highway driving conditions. Interval recommendations vary across sources, and dusty or stop-and-go driving calls for more frequent inspection.
This is a drop-in swap. Open the factory air box, remove the stock paper element, and seat the K&N in the same position. Confirm the filter sits flush and the air box lid closes fully so unfiltered air cannot bypass the element. The manufacturer's stated design is intended for this direct replacement without modification.
