97 Ranger cold intake

[Tlee1214]

My 97 2.3l Rangers got the dual ignition system I've been searching around and there are some people online that have rearranged the wires on the coil so that there's two sparks on the ignition stroke instead of one on the ignition and one on the exhaust stroke. What's your guys opinion on this "mod"?

And to kill two birds with one stone how about a cold air intake on the 2.3 ranger? Any thoughts will be awsome.

There is a thread here on the wire mod for these engines...the verdict is...not worth it...but if you search the 2.0/2.3/2.5 section below you will find it and can read...quite a few posts and very much bickering...not to mention that it will hamper your emissions somewhat because the offset spark helps burn exhaust gases before they hit the cat and can result in higher levels...

The CAI is questionable as to what it will do...and the only thing I've taken from it is it may look a bit snazzier than the stock configuration..."may" give you an extra pony or two if done right and you are not already living in a "Cold Air Zone"

It may add some noise to the engine bay and it will definitely cause you a bit more maintenance and possible issues with your MAF sensor from, if you're not careful, excess oil from the filter (K & N in particular) if you put too much on...it works its way up to the MAF and coats it in oil...

So...it's really a matter of if you want to try it keep all the parts for the original setup in case you want to reverse it...

Fun to play with, but if you're looking for more horsepower just buy a TRS sticker...it adds 5 HP when applied properly to your windshield...

Haha thanks for all the info. I live in Wisconsin so I'm taking it that that's a cold air region. I was just looking to put on the CAI just to do something with my truck because it's compleat bone stock (except a tool box). And as far as the coil rearrangement I just wanted to see if anyone had luck with that cause it seemed way to good to be true! Guy was claiming 5-6 more MPG (city) and 7-8 more horse power which would be crazy.

If your 2.3 is set up like my 97 4.0, it already has a cold air intake from the factory. The K&N one would be a waste of money if you are talking performance wise. As Mark said, it will dress up your engine nicely, but not much else.

couldn't give you much advice on the dual ignition question, but I would say if it were true what your guy was claiming, Ford would have done it that way from the getgo, as that would improve their CAFE rating and be a better talking point for the sales personnel.

what part of Wisconsin are you from? I have relatives in the Wausau and Antigo area

I remember quite awhile ago someone here did a before and after test of the K & N fitler and actually lost a bit of HP, that was with a 4.0L.

I'm about 40 minutes north of Madison it's a little town called waupun. And that's all I would want a CAI for is to look good and for a little sound. What's the deal if I live where it's colder? Does it effect the intake in the winter ?

The spark plug wire change doesn't do anything practical, but if you ask someone who believes it does, then your 4cyl will become a 1,200HP V10 engine with this mod.
Belief is powerful.

CAI(cold air intake) modification is based on the fact that cooler air is denser than warmer air(hot air rises, so is less dense).
The computer for fuel injected engines monitors intake air temperature because of this density difference.
Computer needs to add more fuel to cooler air to get the 14:1 air/fuel mixture.
This is why vehicles feel like they have more pep and power in the winter, they do, more fuel is more power, but also less MPG, another winter cold air issue.

So the performance point of a CAI is to get the coolest air available to the IAT(intake air temp) sensor so it will "tell" computer to add more fuel.
Pretty much 99% of all stock intake air systems do that now, they are all plastic and pull air from in front of the rad support, so it don't get much cooler than that.

CAI systems are about the "look" and sound more than performance, they often use metal air tubes which heat up in the engine bay, so warm up the air inside, oops.
But they do look better.

No, custom CAI won't effect winter driving, or summer driving for that matter

My brother's '97 F-150 has a cheap "BOMZ" CAI kit with the chrome tube and my '02 still sucks from the inner fender like stock. Both trucks run within about 5-10 IAT vs ambient in the summer... no doubt without the baffles the CAI flows better.

More power also = less effort = less fuel consumption to do the same work. Kind of like a supercharger but on a smaller scale. I could drive my old turbo eclipse HOWEVER I wanted to and it never got below 20mpg city. Try that with a 5.0 foxbody with the same 200hp...

Another problem with winter is they also run a different fuel vs summer.
