Air filter

There are 2 filters in my air box can one be taken out to help mpg

 

u only take out/replace that large one thats pleated

Id highly doubt if taking the charcoal element out makes any MPG difference.

what are u getting MPG now?

 

I thought one could also remove the secondary.

 

theres no benefit on the 4.0

the 4 bangers may get a lil more pep, but our V6 has been on a dyno with ALL air filters removed and gained zero hp.

the restriction is in the design of any baffles/kinks in the intake setup itself.

 

if ya want tho
4 cyl

Removing the secondary filter does nothing. It has a purpose.Your best bet is to just keep your normal air filter changed regularly or get a K&N.

 

K&N Filters suck, you can see threw them.

 

I've seen no evidence that it benefits the I4, and there is good research that says it can't.

maybe its all psychosomatic, hell I dunno. Never tried and and dont care to.

I dont have a 4cyl anyhow, but I thought I read a few ppl say they noticed a difference.



then again, I also didnt listen when people told me intakes are worthless
