The little car has a lot more get-up and go with this filter. This is the second filter we've bought from K&N, but for a different vehicle, and we've been very satisfied with both.

Said couple of days on the free shipping. Received it the next day (awesome) fit was perfect. Appears to be good for a 2 mile a gallon increase on my Scion. Have one in all my vehicles.

Works as intended. Fairly easy installation; I use these brand filters in all of my vehicles and have had no problems at all with any of them. Would recommend them to anyone.
