Hey guys , sorry if this was posted already,  just joined, and I'm looking for some info on cold air intakes.  Bought a  K&N assembly then returned it as I couldn't justify spending almost $500 on some clamps, plastic pipe, screws and a filter... honestly,  it was very cheap looking! So back to the drawing board and looking for a cheaper alternative... but with the same quality, hopefully lol.
Does anyone know of a cheaper solution... I know that there is like a kit out there that consists of like the filter and an adapter. I'd like to try and keep the existing/original intake tube, (maybe cut it off near the MAF?)
then install this cheaper modified version... but I'm having trouble finding something or even know what to properly purchase.  Could someone with this knowledge shoot me some advice on what I should do or ideas of what they've done to their vehicle?

Much thanks in advance! 👍

Welcome, I'm kinda an "anti CAI'er" being that what you gain is always minimal for what you spend as you have found out. Also I can't find the articles but sometimes the air is actually colder with the stock ford units being they get the air from outside the hood. Just take your air filter out and look inside the box it is actually a pretty good design.

They do tend to flow better though, I just don't like the fact they call them "cold air intakes" when it isn't true. They should call them "flow enhancers" which is what they really do.

Thanks for that info... yess, it can get pretty costly for what it may or may not really improve. So maybe I'm just better off replacing the original filter with more of a higher end performance filter and leave it as is?

I have the 154 HP 3.0L and it has the same air box as the 4.0L. The restriction point is the intake side of air box. For my truck removal of the intake baffle seamed to help. I had already removed the guts of the pre-catalytic converters which gave it a deeper tone. The two together may have helped but it may have not.

As someone whose been in both the Speed-Shop market and the rolling over God's creations scene as well, I feel compelled to give my $ .02

First two things..  The use of a CAI really only offers its best capabilities if/when you're either constantly reaching those 3 digit speeds and or with the use of forced induction, whether that being of a mechanical form or liquid.  In all honesty, there's a lot of arguments in the communities one the use of CAI and although we can offer them, we could sell them, and if someone really wanted one from our selection; I'd sell it to you if I couldn't get you to change your mind.  Then I didn't want to get into all of the technical stuff and unfortunately Jim here doesn't pay me to teach engine theory & physics classes but unlike a typical piece of random "OK" looking sized tube of random fitting length from home depot and a cone filter. 

An actual CAI has a bit of engineering to it to take advantage of the aforementioned variables to power adders.  Even your OEM airbox, tubing, lengths, diameters, and their materials have controlling factors of velocity, air flow through a specific RPM range, and coinciding with fuel/spark delivery.  All of those, (and I know people roll there eyes when I bring this up but it's the reality regardless of anyone's paradigms) based upon the inflationary attributes to your hard earned cash and thanks to a specific entity, NOT political party, your $500 has less than $77 (yes, thats a real number) of actual buying power compared to a time when the gold standard would have made that same buying power more than $3200 in the year 1970. So although you might feel as if you didn't get your money's worth, it's actually quite the opposite unfortunately for us all.  We're customers to someone too.

OUR suggestion would be to look into trusted brands for cotton oiled/dry in OE airbox filters from K&N, AFE, Volant, etc.. Yes most of them are $40-85 but considering if you bought 2-3 replacement filters prior to or think you will over time, it's paid for itself and then-some with other benefits; such as a small performance bump, washable filter, money savings long term, and a cool noise for those already thinking that should be first.

We deal with a lot of vehicle platforms and almost all of them seem to favor the excitement of finding a water crossings here in the Southwest.  A lot of the snorkel kits don't work with a CAI kit.  Volant claims to for a small group of popular vehicles to offer an intake that will work with snorkels.  We focus on designing/building multi-terrain capable vehicles that are self-sustainable vehicles based upon the needs of the owners, not submarines. ha

There is a build page on here that shows some in-depth work on a clean snorkel install on a '93 Ranger 4.0L build on here, but in summary:

- https://ford-rangers.com/view_post.php?post_id=12446
- https://ford-rangers.com/view_post.php?post_id=12481








Simply uses a K&N inbox oiled cotton filter, not as restrictive as the OE paper, but still filters good in comparison to a foam filter.  we would suggest the same for 98% of the vehicles we come across.  Like I stated earlier, unless you're really trying to push in a mass of cold air, to dump fuel - God forbid with just the factory 19-21lb injectors, and move it through that air pump under the hood and back out again because screw MPG, it sounds cool. Spend $60 bucks on a K&N, and spend the other $440 on some better mods for yourself or take the woman/family out to a nice meal where you'll get more from it.

A lot of the CAI Systems work but they work best when used in conjunction with other power mods like headers and a cam replacement, maybe even a better intake manifold.
By itself the CAI may gain you something but as stated earlier, warn air produces less power and most of the CAI do not have a cooler  external air flow forced against the filter as the OEM Unit does.
Unless you intend to go from mild to wild in the power mods, KISS is the word... "Keep It Simple Stupid"...  no insult meant !

Good Luck on your choice.

Bolting it on doesn't mean you'll gain power or anything for that matter. 

In fact, back in the day, Saturn made the Saturn ION in a supercharged form to compete with the Chevy Cavalier SS and K&N actually made a complete CAI intake complete with an ice chamber to cool incoming air even more so.  Without other mods and tuning, a good customer back in the day on the dyno showed an actual loss of almost 12hp and 27ft lbs of TQ without any tuning.  Once he was able to tweak the piggy back engine management he was able get almost 8.5hp and I can't recall the TQ numbers but it wasn't as high as what was being lost without a tune.

Ideally A re-tune should be necessary with any component that could add/take away performance.  Intake, fuel, air, exhaust, pully or compressor wheel. etc even just a straightpipe mod.
