As subsidiary of Volkswagen, Audi has been producing award winning luxury vehicles (and a short stint of motorcycles) since 1910. With legendary technological heritage and sleek designs, Audi has set the bar for the sports car and sports sedan segments. However, there comes a point in time when a sports car just isn't good enough and that is where the Audi R8 comes in. This supercar incorporates some of the most technologically advanced features on the road and comes standard with Audi's legendary reliability and handling.

Utilizing the amazing Quattro all-wheel drive system, the R8's 430 horsepower 4.2 liter V8 propels it to 60 mph in 4.4 seconds and to a top speed of 187 mph on the track. With all of this performance and legendary styling, how could anyone improve upon it?

K&N stepped up to the plate and gave performance enthusiasts a simple yet effective performance option. Designed to increase horsepower, the E-0668 highflow air filter replaces the restrictive OEM paper air filter in 2008-2013 Audi R8 models, allowing for increased airflow into the already potent V8.

Installation is simple, just replace the stock paper filter elements with the duel K&N high flow air filters and you're done.

Topped off with carbon fiber end caps, these filters not only look good but are also light in weight for added performance. K&N Part E-0668 comes with 2 air filters, one for each cylinder bank, making ordering and installation simple.
