Gasket seal is really tight compared to original filter, (outside edge was a tad to big) had to finesse it into place. Once the lid was on and tightened down it looked like it was evenly sealed. Noticeable increase in performance and fuel economy is better, (2.5 with less than 13,000 miles). I am very happy with price and experience of shopping on the online store. Price was lower than throw away Chinese filter. Thank you! MADE IN USA!

My filter went in easy and was a perfect fit. My city mileage is up to 31 mpg from 26 mpg. Haven't taken a road trip but guess mileage will be up there too. I don't use as much force on the gas peddle to get the car moving. It's power is better with increased mileage, doesn't get better than that.
