K&N replacement air filters are washable and reusable using a K&N Recharger kit, so you can potentially save money on maintaining your 2010-2015 Audi RS5 or RS4 4.2L V8
The 33-3031 and 33-3032 replacement air filters are designed to increase horsepower and torque for 2010-2015 Audi RS5 or RS4 4.2L V8 models (requires both filters)
The Audi RS4 and RS5 are venerable wolves in sheep’s clothing. On the surface, you’re greeted with Audi’s subtle styling and veiled hints at more; including a slightly wider track, slightly larger front grill, slightly flared fenders, and small splashes of red from the RS logo. But get in the driver’s seat and bury the throttle, and you’ll experience the wolf bare its teeth. The 4.2 liter V8 howls all the way to 8300 rpm, generating 450 break horsepower and 316 pound-feet of torque along the way. This beastly power is shunted through a seven-speed dual-clutch gearbox and Quattro all-wheel drive to leave nothing but the most ferocious of grins on your face as the wolf slices its way through unsuspecting corners. This performance doesn’t come at the cost of comfort, as the RS4 and RS5 still maintain the refinement expected of fine German automobiles.
The question then becomes “is there room for more?” The answer is a resounding yes. Simply replace the disposable factory air filters with K&N 33-3031 and 33-3032 performance replacement air filters for 2010-2015 Audi RS5 or RS4 4.2L V8 models.

These Audi RS models have two engine air filters, and require one of each 33-3031 and 33-3032. Both filters have a durable urethane sealing lip, precision-molded to provide an air-tight seal in the factory air box. At the core of these performance air filters is K&N’s oiled cotton gauze filter media. Four layers of cotton gauze are offset from one another and impregnated with oil to provide a high-flowing filtration media that also ensures excellent filtration efficiency. Your Audi V8 will thank you for allowing it to breathe easier and perform better.
