Easy to install. Great instructions. Gas milage seems slightly better so far. Improves throttle response quite a bit. Great product!!

It's a great filter. I love it and it's awesome talking about it. The description said it would fit in my 1997 Bmw 328i but it's almost too big. I'd say it's about 1/8" in width (if you were looking down at in your car, top and bottom). I had to work it, but it's in there. I still will buy another.
