NAY for my major nose dive in gas mileage! All I did was change the filter and BAM, mileage went from bad to worse....as in from 20 to 16. I think its because that filter is more restrictive due to the very small micron allowances.
I changed to an AFE Pro Dry S and my mileage went back up to 20 to 21 range. Keep in mind that I drive and explorer. A small car that doesn't require much power to get itself rolling will not need nearly as much airflow and might not be affected by a close tolerance filter like this one.
Me Too! No lie!
I bought a standard Puorlator Air filter for my 04 Altima 2.5 and the mileage went down. No Lie! I put back the original factory filter on the next tank full of fuel and the mileage went back up. I keep both filters now and play around with them. And No Lie! Every time I put in the Purolator, the mileage goes down. This has been going on for 3 years now. The factory filter is really only a bit dirty and the Puro is clean so I don't get it!
