It's just like a normal filter, not seeing any difference in the mpg,or hp. It's better than stock.

Goo quality but very tight fit in stock airbox

If you are looking for a filter to replace stock that you will not have to oil or ever replace this is a good deal. Fits the stock air box but is just a little taller so getting the cover back on the box is a little harder. I read other review where people thought it help with response and maybe a little mpg. I did not experience any of that since installing.

Ecodiesel and Synthamax

Easy to install and fits well. No discernable power difference or mpg gain nor was one anticipated. I bought it to save money over the OEM filters and anticipate that being the case.

Great Quality

The quality over the OEM filter can't be beat.
