Installed a K&N air filter in our 2002 Toyota Avalon and got better idle quality, better acceleration and better performance in general. In 1971 I installed a K&N filter on my Yamaha motocross bike and saw an impressive gain in performance... needless to say, I've used them since that day.

The E-1983 is very similar to the K&N filter that I installed in my 2014 A-6 Quatro. The filter in My A-6 did a fine job and I would expect this filter to perform just as well in my New A-7 Quatro. I have used the cabin air filters by K&N in my 2011 Subaru outback Limited. It also performed better than the OEM unit. Here in Texas, we have a lot of wind and dust to contend with on a daily basis and K&N protects my engine and cabin interior exceptionally well. Cleaning of the cabin air filter and the engine filter is simple and essentially gives me a new filter for the next 30-50,000 miles. I would rate those things that I have used from K&N with five stars in every case. Sincerely, Jay Helt Frisco Texas

I've only had the K&N filter in my Subaru Outback for a few weeks, but I noticed an immediate increase in power.  The exhaust even sounds a little throatier. Website was a breeze and delivery was very quick. Thanks
