A bored out t/body will do nothing for fuel economy. It won't help
performance either, other than at wide open throttle.

It goes without saying that if you're "enjoying" your "performance
increase" from a larger t/body, you're not gonna get any fuel mileage.

These are average figures, but I went from about 20 mpg in stock
configuration to about 25 mpg after the bored out throttle body, cat back
exhaust and electric fan. This was with the 2.5 liter engine. I believe
that in the stock configuration, the vehicle runs a little rich in order to
keep NOx emissions down. Most modern vehicles doo. According to spark plug
appearance, the vehicle isn't running too lean now, but the gas mileage is
improved, according to measurements made over 7 years. In my experience I
couldn't measure or evaluate the alleged performance increase I was supposed
to get, but the mileage increase is very real. The fact that you might
believe this to be impossible doesn't change the figures I have written down
in the notebook I keep in the vehicle.

One thing about the fan. The four cylinder engine doesn't need as much
cooling air as the six, so I can drive down a highway or even a gravel road
and it will never come on. Usually, the fan only comes on in the summer in
city driving. That is why it represents a fuel savings, because it doesn't
have to come on and therefore use engine power. Your six cylinder
experience here may be different.

Now if you put in at least a cat-back exhaust, which sooner or later you
will have to replace because of rocks, rust, whatever, well it seems to have
helped the Jeep and the Suburban I have too. And you can't argue with the
cool sound it makes.

Your fan swap probably did more to increase fuel mileage than anything
else; belt-driven fans soak up a lot of energy.

> And you can't argue with the cool sound it makes.

They're attention-getters, but they don't make more power or burn fuel
more efficiently. I'll pass on the extra attention; I get enough from
local cops and thieves as it is.

Hi Earle,
You replaced a badly needed air filter and cleaned the Throttle
Position Sensor at the same time as the bored out throttle body.
