So I just got back home from a ~2200 mile trip from Firestone, Colorado to Richmond, Texas. I drove the first 1100 miles to Texas with a cheap stock-replacement filter. While I was there I went and purchased a K&N filter to see how big of a difference it made. Also, I am running 265/75/16s and the only other powertrain upgrade is a Flowmaster 50 SUV muffler. Here are my findings:
Trip to Texas with stock filter-
Avg. speed: 68 mph
Avg. Intake Air Temp: 73 degrees (readings taken every 30 minutes)
Avg. mpg: 18.1 mpg
Trip back to Colorado with K&N drop-in Filter:
Avg. speed: 68 mph
Avg. Intake Air Temp: 64 degrees (taken every 30 min once again)
Avg. mpg: 19.9 mpg
So I saw close to a 2 mpg gain with just the drop-in filter. And also keep in mind that on the drive back I was climbing just under a mile in elevation. BTW, all my reading came from a scanguageII. So, I hope this can help some of you out who are looking for a semi-cheap upgrade. In my opinion, this was a great upgrade as the filter is also washable and have a million-mile warranty. If you have any other questions, just holla!!
