This is a direct replacement filter. Fit was perfect, quality is perfect, (I wouldn't order if it wasn't) and I can tell an improvement in fuel mileage over the stock filter, and yes, the stock filter was dirty but the dealer told me it wasn't ready to be changed yet. Best of all, I never have to buy another air filter for this car again.

The K&N air filter that I installed in my 2013 Equus has given me additional power and better gas mileage as K&N advertises. I also have a K&N air filter installed in my Infiniti M45 and the same improvements discussed above apply to my second auto as well.
