Hi Joe,
On my 97, the V8 used a square air box in the front Pass. side of the
engine compartment for the air filter. It had a wimpy little 2" X 1.5"
oval snorkle for the inlet that went forward thru the core support to right
behind the headlight. I just made the hole in the front of the stock
airbox 4" in diameter, made the hole in the plastic shield on the core
support 4" dai also, and put a piece of 4" dia PCV pipe in place of the
stock snorkle... I'll take it apart this weekend and snap some pics and get
them posted on my web site..
For your KKM, you could get a piece of PCV pipe the same I.D. as the
largest dia of the cone filter, and get a pcv fitting on the end to reduce
it to 3" or 4" dia and use some 3" or 4" flexi hose to run it where you want...

Definitely... The less restriction in the tailpipe, the more sound you'll have.

Straight pipe shouldn't hurt anything, but it may flow enough that the EEC
can't compensate with enough fuel... Might get an adjustable fuel pressure
regulator and crank it up 2-3 PSI over stock to make up for the additional air.

Hi Adam. While searching for info on EGR sensors, I see I never
replied to this post you sent to the list a few months ago. (Hadn't
read it to tell you the truth.)

Does your truck have an automatic or manual transmission? Even if
your vehicle is in tip-top shape, if the gear ratio is not efficient,
your gas mileage will suffer (especially if you have an automatic
tranny). However, the differences in gas mileage between automatic
and manual trannies has blurred to some extent in recent years.

Anyway, my gas mileage driving to from work (50/50 mix between
highway and city roads *timewise* - mileage is about 60% highway 40%
city) is about 21-22 mpg. However, I think the 30 mpg I got before
may have been a fluke as I've never been able to duplicate that since
that earlier trip. I bet that the tank of gas caused that. Typically
we're in the 25 mpg range for highway driving.

We have a Mitsubishi 5 speed transmission (Overdrive) which was
recently replaced with one from a junkyard (which had been recently
rebuilt - yeah!) However, we're now regularly getting complaints from
the computer about the mixture being rich and about the EGR sensor
not working properly. I wonder if I'll be able to duplicate that 30
mpg again if I replace the sensor?

As I'm not passing PA emissions, I hope that replacing the sensor
will bring us back into acceptable limits (as well as increasing gas

By the way, we're planning on selling the truck next spring (want to
have 4WD during the winter). While I like the truck, it is getting
older and I want to sell it while it's in good maintenance. If anyone
has any serious offers, let me know. It has 125K miles on it now with
newly rebuilt tranny and new clutch. We had the flywheel resurfaced
and replaced the rear engine seal. In addition, we replaced the
U-joint on the driveshaft which supplies power to the front wheels
and it runs really smooth. It is a gray 1986 Bronco II with 2.9 V6,
4WD (and great gas mileage of course).

FoMoCo.. try one tooth smaller than your current gear located at the end =

holding the retainer in place. Remove the bolt and pull the housing out
(possible fluid loss so a catch pan might help). Usually the number of t=
is stamped somewhere on the gear, but if not count and RE-count the teeth=

On my '85 B-II with 4.10:1 gears 31x10.5s made the speedometer off by abo=
7-8% (ie: 50=3D54 100=3D108 on the dyno) I don't know if the previous o=

it recalibrated for the 235/75s he was using or not but for the small
difference I haven't bothered to reacalibrate mine. In general I just pu=

speedometer on the speed limit and know that I'm a few over until I hit t=
higher limits like 70 where the percentage means a little more over... I =
65 (indicated) and it works out to about 71 or so as I recall.

Two cell phones or CB/Ham radios help for instant comparisons of the
