I recently decided to change my air filter and ordered the AEM dry filter after seeing many users recommend it.
While It was in the process of shipping, I took my stock filter out to look at it (fairly clean actually), but knocked some fine dirt out of the filter in the garage floor. I vacuumed the inside of the air filter box that had a small about of dust/dirt etc and put the original filter back in until the new filter arrived.
I noticed immediately that i was getting worse MPG. Flat freeway at 65mph my “current mpg” was 16, when prior to checking filter it would be around 20 on that same stretch. Truck seemed “off”, but can’t pinpoint why. “Average” mpg also dropped slightly.
The new AEM dry filter came and I swapped in the new one. I’m still having a noticeable drop in MPGs compared to when I first checked the stock filter.
Is there any reason this could be happening? Did I install it wrong? I unscrewed the bolts, took the filter out, but new one in, closed box and tightened screws. The box appears to be shut completely.
