Cold Air Intake for 91-94 Explorers

[pughman]

ya , thats what i got, that help elbow...

 

[ExporeRanger]

thanks a lot..thats perfect..n ya throw up sum pix

I used a shower drain for my maf adapter cost 3.99 and took about 20 min to trim it to fit and drill the holes in it to mount the maf and paint it (primer and black paint). for the intake pipe I used aluminum dryer vent hose and bent it to the shape I wanted and flattened it out to go across the radiator then instead of taking it to an exuast shop to get a chrome tube bent I just wrapped it in black header tape. then bent a piece of .440 stainless steal (polished) to use as a heat shield for the filter. total cost about $35.

yeah. i was reading the thread. does anyone know where i can get cold air intake for my explorer? its a 94 and 2wd.

and my explorer has the sound system thing n all that.

-if you were reading the thread you wouldn't have that question!

BDAb.. get some pix up of that if you can..i'd like to see this heat sheild..probably pretty cool lookin..and i like your creativity..lets see it man..

and for the FINAL VERDICT!.. if you bypass the oil breather and put a lil filter on it, instead of connecting it into the air intake tubing..does it do anything negative OR positive?

beings how that paticular explorer met an untimely death on a trail next to the spokane river (ended up in the river) I no longer have it, but I think i still have my template that I used and even if i don't it wouldn't take long to make a sketch of what I did and if can wait a few month i plan on making another set up exactly like it for my new used 92 explorer. keep in mind this was not a show piece and I believe in funtcion over form, the only reason I used stainless is because I had a small piece laying around from my knife making phase (long story and i lived in Timber Oregon at the time and actually had a market for home made knives) but I am about to build stainless steal tank skirts for the peterbuilt and will have left over steal but give me your email and i will send you a sketch and measurements for it. and the trick for polishing it to a mirror finish is lots of time, if you know how to polish boots (like in the army) you can polish metal.

There are several schools of thought on this, but in the race industry, anytime you can help draw crankcase pressure and contaminants out the better.

 

[pughman]

in the race industry , they just put a lil filter on it, instead of connecting it into the air intake tubing, i know , i help run a late model at the adrian speedway....

Here is an interesting read for the pro side of crankcase evacuation, though something like this may be extreme for a 4.0L in which case a breather line or filter will both work just fine, just as pughman will attest.

[pughman]

right , i have seen 1000 hp top fuel run the "use exhaust as a source for vacuum to suck the gas out" but even 400 to 500 hp nascar motors's run just breather's , so if your 4.0 puts out 1000 hp you might need some kind of crankcase evacuation..

seriously that hood cowl is ####in rediculouse.... theres no way that could even come close to looking good on an explorer, keep it on the mustangs...

If I remember right, Pughman NEVER asked for your opinion on his hood. I happen to think it looks pretty good on an explorer. Maybe you should grow up and learn to keep your thoughts to yourself. Oh, and learn how to spell, buddy. It's "Ridiculous" for your information. I'm not trying to sound too harsh, I just believe comments like that have no place in a forum like this one.

 

[pughman]

thanks man , some people have big hood invey ! lol...

and i do have one on my mustang...

and there is lots of explorers with cowl hoods...

o ya and look in my avatarwitch you dont haveand you can see mine

 

[skoobydoobiedew]

hey no problem : )

What's the part # for the K&N or S&B cone filters? I have a huge K&N that I modified to work, but as I said it's a huge cone filter. I'd like to get the correct filter.
Thanks

I have a Ford Escort that is the daily driver. Different than the Explorer, I know. I custom made an intake for that using 2" ABS piping. All I did was just look at the curves, bought the right elbows and glued it up as I went. I noticed more of a top end (its a 5600 rpm redline if that counts as "top end" ) power but a loss low end response. Its sounds like a beast too. Is it the same with the Explorers?

Another little trick I learned....

The Escort's air flow sensor is also square and flat on the filter side. The stock K&N filter wouldnt fit up to it even with an adapter. I had a large o-ring from an oil filter that was just the right size. I put that on and then drilled 4 small screws through the air flow holes and into the steel base of the K&N. Works perfect.

And also on the car, I just put the stock one way PCV valve back on the valve cover and thats it. It would be nice to draw the gasses out of the cover, but Im not about to drill and make a mess out of my intake. And a vacuum line straight from the intake manifold sucks out the oil too, so thats a no go.

Here's my 2 centavos on intakes based on my personal experiences. I started with a K&N replacement filter for my 4.0 97 Ranger and noticed very little if any difference. Then I won a KKM at a Serious Explorations raffle (thanks Rick ) and put that on and noticed a bit more difference over the K&N. Now although it did FLOW better I feel that neither the K&N and KKM FILTER any better than a paper filter. I say this because I took off the intake plenum once and notice quite a bit of residue from the oil on the filter. It took a full can of carb cleaner to get the plenum clean again. Now i've switched to a foam style filter from True Flow so i'm gonna see how that works out. You still have to oil the filter like K&N and KKM so i'm a bit skeptical about it's filtering abilities. I am in now way saying that any of these performance filters are bad, i'm just looking for a good filter without the oily residue it leaves on the intake. I still feel a paper element is the best at filtering contaminants but not good as a performance intake like K&N, KKM and others.

I live in the desert and take my truck on extremely dusty trails when I go offroading so as much as i'd like the performance side of an intake, i'd rather it filter out all that dust

I just took my throttle body off and cleaned that and the intake plenum. Everything was oily/dirty and the truck has been using the paper filters since it was made in 91. If the exhaust gas recirculator or the valve cover vacuum are connected to the intake, one would think that would be the cause of the majority of the buildup.

I got that same kit off of E-bay for $143, shipping and all and just installed it today. I LIKE IT! When you get on the gas, you can hear it growl! I know I could have fabricated it, but I liked the shiny tube!, plus, its a smooth air shot into the intake manifold now. Not like with the stock plastic ribbed one. Don't know about gas mileage increase yet.
