Napa air filter

[werkenklasse]

Hey Guys,
Got a 2001 F350 7.3L CCLB with an auto trans. I have the stock air filter system and was looking for a different air filter to get better mpgs. I have used a K&N in my old 7.3 and didn't like what it did to the air intake hose. I have heard that you can do some work with the intake system and purchase a special Napa filter for the 7.3. Is it true? If so, does it really get better fuel economy? I get about 16.5 on the highway empty, and about 12 hauling a 4k trailer in the city.

Here is a hastings number for what you want AF2329. I converted from a napa number. This filter has a 4" outlet that you need a short piece of exaust pipe to conect to the intake hose. I took the air filter box out of my truck and this filter lays on the fender where it was. Cost was about $40 an it puts K&N right to shame.

Great! Thank you so much. Does it really get better fuel economy?

I installed the napa 6637 two weeks ago and the mpg gauge on the truck shows an increase of .6 mpg. The performance does seem better, just accelerates a little quicker. If I were to keep my foot out of the throttle and drive the same as I was before the filter, the mpg my be a little better. The turbo does make a lot more noise than before. It don't bother me, but may others.

When I installed the DIY intake I didn't notice a significant increase in fuel economy. Opening (straight pipe) the exhaust was the magic ticket.

Did opening up the exhaust really help? I've herd so many people ( on this site included) say it didnt help a bit. I'm still running stock exhaust but have been thinking about going to a straight pipe

Absolutely, more boost, spools quicker, lower EGT's, definitely better!
