Fram air filter for TJ-poor mpg
 

About 2 weeks ago, I put new plugs and a new air filter in my 03 sport.
I used the stock champion plugs. It has about 45k on it. Oh yeah, it
is a 5-speed, 6cyl, all stock, etc.

No problem with the plugs. It was the air filter.

I bought a fram, which I usually wouldn't do, but...

The air filter had a 3/8" block of black foam glued on the bottom of
it. I've replaced the filter before, and never seen this.

My mileage instantly went from about 17mpg down to 14.5mpg. this went
on for 3 tanks of gas. My tire press. was ok.

the only thing I could think of was that strange piece of foam loosely
glued on. So I took that piece off. To say the least, it was barely
glued on.

And my mileage went right back to 17.

So when did they start gluing blocks of foam to their air filters?
And why, especially if it's going to kill your mileage. It's the same
dimensions, pleating and all, as a stock filter.

The OE air filter also has that same type of foam glued to it. I doubt
it was the foam itself.

Re: Fram air filter for TJ-poor mpg
 

LOL!

Aha!

Something has ben bugging me about the new Jeep's crappy mileage....

Some folks say they can get 17 to 20+ mpg which is getting a bit close
to what the old 258 carb engine gives me and what my Cherokee 4.0 gives,
23+ mpg and others say they only get 13 - 14 mpg....

Could it just be the air filters? I don't use foam covered filters.

I think that would sure be worth looking into!
