Has anybody installed a K&N in the EXPY? If so what kind of difference are you seeing if any?

I am too worried about messing up the MAF.

 

KEEP THE PAPER FILTER, REPLACE OFTEN.
You will find little gains in all aspects.
KEEP PAPER FILTER, A tuner will problably serve you better.

 

I used to be a huge beliver in K and N. While I think the filter itself is build well and they have their place in cold air intakes, etc. I think that you have to have the perfect oil content in the filter to get a good balance between airflow and filtration. Too much oil, restricted airflow, dirty MAF sensor, etc. Not enough oil, great airflow, not great filtration.
I am sticking with paper for now. Prices are high, but they should come down.

Oh, and on the two trucks I had KandN filters on, i noticed no increase in anything.

 

Thanks for the info.

 

I've got the K&N drop in and noticed no increase in milage. I did however have no issues pulling a #5,500 30' travel trailer between Phoenix & SanDiego against the wind both ways!

 

i have the drop in K&N and have noticed better throttle response slightly. Plus it was $30 and the paper ones are close to $20 and are not readily available near me except at the dealership.

I have used K&N type filters in my last 3 cars/trucks and have never had an issue, and I usually keep my trucks to at least 100K.

Personally i wish someone would come out with a cold air intake so i can remove the crappy stock piping. Has anyone taken it off and looked at how restrictive it is. It is unbelievable.

 

I wonder? In my last truck 2004 yukon i put a drop in K&N and also had flowmaster dual exhaust and it made a huge difference in kiddy up and MPG.....I was just looking at the gibson dual exhaust and CAI from K&N.

 

arent you the guy who said dont modify your new truck on the 07 expedition lift thread?

You say to keep the paper filter and add a tuner, tuners void the warranty alot quicker than any suspension changes.

Plus there are no tuners available yet for the 07 expedition, I have already checked, plus if you do get a tuner you will need more air flow than that paper filter will ever give you.

 

C'mon, paper will move more air than the TB can.

 

No i didn't say that, that was someone else.

I added a drop-in K&N and gained almost 1 mpg. it's worth the $30.

 

plus you dont have to keep buying $20 paper ones.

 

I think I'm gonna go with the K&N CAI and dual Gibson performance Exhaust.

never mind, K&N does have a cai. Smart way to make it, clicking on top of the existing box, that way you dont have to cut it out.
