Re: Fram air filter for TJ-poor mpg
I didn't start charting my mileage until after I got a clone K&N. But I
know if I drive smart I've gotten upwards of 20mpg...best was 22mpg....but
I'm usually 17 just keeping up with the F1 drivers on the 400!

Re: Fram air filter for TJ-poor mpg
If I run 120-130 kph on the 400's I get about the same drop. If I kick
back at 105-110 or so I get better, the 23 mpg or 11L/100 km. On Hwy. 7
running less than 100 kph, closer to the speed limit of 80 I get up to
26 mpg.
I have a 200 mile gas station to gas station trip I take regularly so
have lots of chance to check it. Almost $5.00 more to run it with the
front hubs locked in because of snow potential on that 200 miles.
I run a generic filter air I believe. Chain store brand. My carb stays
pretty clean for all the dirt I run so they work well. Been using them
since the 70's on all my vehicles.

back at 105-110 or so I get better, the 23 mpg or 11L/100 km. On Hwy. 7
running less than 100 kph, closer to the speed limit of 80 I get up to
26 mpg.
I have a 200 mile gas station to gas station trip I take regularly so
have lots of chance to check it. Almost $5.00 more to run it with the
front hubs locked in because of snow potential on that 200 miles.
I run a generic filter air I believe. Chain store brand. My carb stays
pretty clean for all the dirt I run so they work well. Been using them
since the 70's on all my vehicles.

Re: Fram air filter for TJ-poor mpg
If I run 120-130 kph on the 400's I get about the same drop. If I kick
back at 105-110 or so I get better, the 23 mpg or 11L/100 km. On Hwy. 7
running less than 100 kph, closer to the speed limit of 80 I get up to
26 mpg.
I have a 200 mile gas station to gas station trip I take regularly so
have lots of chance to check it. Almost $5.00 more to run it with the
front hubs locked in because of snow potential on that 200 miles.
I run a generic filter air I believe. Chain store brand. My carb stays
pretty clean for all the dirt I run so they work well. Been using them

Re: Fram air filter for TJ-poor mpg
A K&N is ok for a street vehicle but it filters too poorly for a Jeep
that is offroaded in dusty conditions. Tests show it really lets the
fine dust through, not a good thing. I have to run a K&N because my OBA
compressor takes up the space where my OE air filter box used to be but
get it so it was filtering well enough for my desert wheeling, I ended
up placing two pre-filters over the top of my K&N. Yes the combination
can still provide more air than my 4.0L engine is capable of consuming. :)
