 As always awesome product.. Run in all my toys... Thanx

 I installed this filter on my '08 VW Rabbit in no time. My first time replacing something by myself in my own car and it was actually fun. I gained about 10 horse power and I'm very confident driving. Super cool stuff and yes yes yes I will be back to buy more.

 Based on a long history of using K&N, I replaced my wife's VW Bug. The instructions were limited as VW has an interesting location for the air filter (under the VW engine cover). Popping the cover took some time. Once popped, then a couple of screws later I had the filter replaced. I am less than a month on the new air filter so can't comment yet on how well it is working.
