The '94 Pathfinder is rated for 14 mpg city, so maybe a plugged cat or muffler was causing the 9 mpg. My Ranger didn't get any better mileage with the K&N, and actually got worse mileage once the K&N contaminated the MAF. (The fact that the pinging eventually blew the electrode off of a spark plug probably didn't help either.)
