aFe Pro Dry S Air Filter MPG and Power Test: Does it Help?

[@waynesanders1406]

It's nice to see someone take the time to test something for the review for a change instead of just making a video of putting in on and never updating what the aftermath was. What part of Colorado? I just moved to Lakewood outside of Denver.

Aurora, welcome to Colorado!

Awesome review! Convinced me to purchase one for my car too.

[@Wallymakesstuff]

That’s great! Let me know if you notice a difference!

I just ordered a proguard 7 for me and 1 foe my dad's truck too. Curious to see.

Great review,thanks for doing this testing as I installed one of these dry filters in my 2005 Sprinter which is way underpowered with a 2.7L Turbo diesel as I was hoping it would give me a little more pickup and a little better mileage. With the stock 15 inch standard hwy tires I was getting about 20 to 21 miles per gallon but I upgraded to larger AT tires that are about an inch and a half more in diameter as I do alot of camping put in the sticks and travel on dirt roads. So now it seems that based on the odometer and doing the math on the gallons of fuel being used I am getting only around 16 to 17 miles per gallon which is a significant drop. I did not want to go through the hassle of having a dealership mess with the tire wheel sensors so I just installed a GPS monitor for MPH and some other features like a compass etc. I noticed that the van is in reality going two more miles per hour than is showing on the vans speedometer, so im wondering if I need to recalculate the mileage and add 2 more miles to the total miles the vans odometer is saying I traveled for me to get the actual mileage? Im asking because you mentioned using your larger tires and going by a GPS for your miles traveled when calculating correct mileage. Any advice would be appreciated.

[@Wallymakesstuff]

Yes, you have to do the math. If your circumference is 10% greater than stock, for example, then you’d add 10% to the mileage based on your odometer. Or just use the gps mileage to calculate it instead. You’re probably getting 1-2 mpg higher than you think.

[@treasurefinder7753]

@@Wallymakesstuff Thats about what I was thinking as I could not believe that the mileage dropped that much just by adding an inch an a half to the diameter of the wheels and the tires are also made for HWY use so they are not real knobby. This really makes me feel alot better about things. Thanks again man for taking the time to help out those in need. Do you still feel like now after more time has passed and testing on that AFE dry filter that you are still getting improved mileage at about 2 more miles per gallon?

[@Wallymakesstuff]

@@treasurefinder7753you’re welcome. Yes - I think the mileage did improve about 2mpg highway, probably 1 in town (the higher rotation diameter takes a bit more throttle to get up to speed in town). I also removed that carbon filter at the same time though, so it’s probably a combination of things. It’s worth a try since you’ll save money on filter replacement anyway, at the very least.

Nice video. Can we get an update on how much dust and particulates are getting by the AFE compared to the Wix. I know you cleaned the inside of air box was wondering if it is any dirtier than wix. Thank you

[@Wallymakesstuff]

I just recently returned from a dusty trip, and the air filter was loaded with particles, but I couldn’t find a trace inside the air box behind the filter. I was shocked, especially with all the chatter about how these don’t filter as good as a disposable one.

[@BR549_o7]

is there a follow up video on this to show if the air filter housing still has dirt/dust on the engine intake side of the housing like you had with WIX?? (to prove better or worse filtration)

[@Wallymakesstuff]

No, not yet - but I’ll tell you I just cleaned it out after a really dusty trip and the housing was spotless, not even the slightest residue

[@paveio]

Any idea how many lyiers of poliestere does It has? I am gonna try One of those!

[@Wallymakesstuff]

Not sure… but seems to be doing a great job so far!

[@joehelbok8184]

Recalibrate your speedometer for the bigger tires and you won't have to do the extra math and your mileage on the odometer will be correct. The edge CTS 3 does it and much more I put one on my tundra and now my speed and mileage is accurate

[@Wallymakesstuff]

Very cool, didn’t know you could do that! Thanks for sharing.

[@civic.9988]

Did it make any sound difference?

[@Wallymakesstuff]

No difference in sound

[@robinator503]

From what ive seen its not worth .1 seconds 0 to 60. The AFE lets in bigger particles
