I received the filter on time and I was able to install it with ease. On the 1st tank of gas I had 2MPG improvement. I continue to average 2 to 4 MPG better.

Got the green filter in hopes of getting better Gass millage not for power as most do,i drive 70 miles round trip to work. I also modified my airbox by cutting 2/3rds of it and made an intake similar to the FS works for $100 bucks less. The green filter looks to be well made, on par with any K&N I have ever bought.The intake sound is much louder now vs stock, but in a nice deep way. Mpg test not done yet. Well see.
