FREE!! CHEAP!!!! MOD!!!! (seriously)

[Pheonixx77]

lol

im sure you guys have seen this mod before, but since i did it yet again to another vehicle i thought i'd post it up.

its sort of free, you need about 20 minutes, some patience and a drill with a 3/8" paddle bit. Paddle bits work better because the sharp point grabs a lot easier than a drill bit will. Don't forget to vacuum out all the plastic shavings! Drill carefully and let the drill do the work, do not push or you may break the plastic, and you run the risk of pushing beyond the box and hitting something important...like a radiator hose or your head lights or your coolant reservoir.

I've done this on my ranger, explorer and my F150's air boxes. works really well.

--------ONLY DRILL THE BOTTOM OF THE BOX DRILLING THE TOP WILL ALLOW UN FILTERED AIR INTO THE ENGINE---------

anyways, this is what it will look like when done

what about this confuses you ericautopart?

this has been tried and tested on 3 of my vehicles, and I've seen the mod all over the net for years. it does essentially the same thing a cone filter on the end of a shiny tube will do without all the cost. Sure there's a little bit less CFM but i don't plan on racing this truck. I can tell you without a doubt there is a huge improvement over stock CFM.



ill take the 100 bucks i saved and put it in the gas tank and take the wife for a ride.

I'll take the 100 bucks and buy baby clothes and leave the holes out of my airbox. The benefit of drilling holes in the airbox is demolished by the dangers of doing so. You are allowing more dirt into the engine, decreasing the life of your air filter, possibly letting larger objects to clog the air filter, and of course the chance of hydrolocking the engine always exists. Cone filters were designed (the good ones anyway) to combat SOME of this. Either way, you aren't gaining anything other than a possible slight growl.

how am i allowing dirt in the engine? I drilled the bottom of the box...the part before the filter. as to hydrolocking ...well how is it increased over an open element cone filter? but hey ive ran both drilled airboxes and open cones since 1995 never had an issue with water, bugs or more dirt. but hey, ive only owned explorer's rangers and f150's since 1995 i may have missed something along the way...

 

[ericautopart]

No, you are increasing the chance of hydro locking over a closed off sealed air box. Hey man, it's no big deal. I didn't understand it at first. It doesn't make sense to me and I wouldn't do it. Now that you've explained your side, I get it. Just not worth the risk to me. Good luck!

Dont know its looks so bad, i just had this from ebay 1 month ago and it does do an improvement, am happy with it and budget on mind cause 200$ for an intake kit was to much..

I posted the installation on a new thread

it does allow more air flow, but that air flow is the heated air in the engine compartment. I you put a K&N filter in you stock airbox it will flow more air and still pull from outside the engine compartment which is cooler. Just be sure to clean and oil it at least every oil change to keep it functional.

just commenting on hydrolocking and stuff.
- most air pickups are lower than the airbox
- in a sealed system that means as soon as the pickup(tube) is submerged the engine will start sucking water, seen cars ruin engines in 1 - 2 feet of water.

having holes in the airbox as shown will let the water escape as soon as it does reach the airbox (but it never will with the holes, since water is heavier than air).

Cars are more more susceptible to this condition.

The only time ericautopart's comment would be true is if the pickup(tube) is higher than the airbox, and you manage to drive through water to fully submerge the airbox in water so all drilled holes were under water.

As far as the dirt and stuff clogging the filter faster, it's only true if there is a screen on the pickup(tube) that has holes smaller than 3/8", you would need to check if such a screen exists on the pickup(tube).

im cheap and like the idea but i dunno,this is the first ive heard of this before.

 

[rokr1292]

Why not just remove the silencer and forward air box?

 

[Sparky94]

I think you were a little too happy with your drill... haha but that's an idea!!! This isn't as cheap, but it is a cold air intake:
