The air filter was a perfect fit on my wife 2011 BMW 328i.

Replaced the stock BMW air filter with the BM-1113. Fits the 2013 R1200GS water-cooled engine. Great filter.

2011 Mazda6, 2.5 auto pulled 32 mpg from Fresno to San Diego, AC on, and hauling butt. I also have one in my 84 BMW 325e, 2.7 5spd. 30+ freeway, all day long.
