K&N Air Filter Mileage Drop

K&N Air Filter Mileage Drop
I filled up again today and I got 13 MPG. This is after getting 15 mpg on the freeway last week.
here is a post I made about the low freeway mileage last week.
The question is could the drop in mileage be due to the new K&N air filter I put in 2 weeks ago?
I also dropped in 4 Boshe Single Platinum plugs. I only put in 4 because I can reach the other 2. Could this be causing the drop in mileage?

i gapped my plugs to .054 because thats what i thought the guy at the auto parts store said. When I replaced my plugs I had to remove the wheel well and there were 2 hoses connected to a ball. Does this have something to do with the vacuums? I did hiss when I removed the hoses. I did plug them both back in.

your first problem is with the brand of plugs you installed......your second problem is you NEVER replace just one plug (i had a dead plug in my truck and i replaced them ALL).........and if you didn't gap the plugs to the right gap, you could lose milage fast...
the K&N is NOT the problem....

Not to turn this into a spark plug war but the Bosch plugs can be the problem and since you only changed 4 of them that is making it worse. The K&N will not cause the drop in mileage but a bad gap or bad plugs will. I've always used Autolite dp plugs. The Bosch made my truck run like crap. But if you always use the Bosch plugs and have no problems just change the other 2 like everyone suggested.
