2003 Wrangler 4.0L - gas mileage
 

I was wondering whether anybody has tried the K&N air filter or a
throttle body spacer to achieve better gas mileage with their late model
Wrangler 4.0L engine?

I'm not too upset about the gas mileage I am getting, but if either or
both of the devices mentioned above actually work, I'd probably go for
the investment.

Anybody have accurate before/after stats on either device?

- thanks

Tom

Some like it, some don't. If you keep it clean and oiled
properly it probably works. But some have said it lets
dust in that stock filters don't.

TB spacers are utter garbage and so are the "Air Tornado" things.

The best way is to use the lowest octane fuel you can that
doesn't knock, and keep a light right foot. The rest is
anticipating traffic so you don't use the brakes much.

That and driving something more aerodynamic than your
average brick. :)

I ran the K&N drop in replacement filter for a while... no difference
whatsoever that I noticed. As for throttle body spacers, I think most
will tell you that they are nothing more than 'snake oil' on a Jeep,
and not worth your time or money.

It's probably the winter fuel too. This always produces less MPG. BTW,
what are you getting with your 2003 TJ for MPG?
