I cannot justify spending $300+ on an intake. So of course, my natural 17 year old instincts tell me i can make one

i've seen several custom setups that look appealing and actually make use of the brake ducts. Most of the setups involving stock airboxes have to do with some sort of "ghetto" rigging of a tube down to a brake duct or somewhere similar. My only question is that i've heard horror stories of engines being blown from intakes sucking in water. i'm not planning on screwing up my car ... and for sure, i'm not gonna do it with some simple, yet stupid $5 mod of my own engineering.

what are the dangers/chances of sucking in too much water? i've heard a few agurments about how if the tubing is wide enough, there's no vacuum, and things like that, but has anyone ever experienced this as a problem?

thanks

alex

just pay attention to details when you do it. It'll cost you around $40 (thats' what i figured for my last car) plus the cost of the filter if you do it right. You can make it outta steel (need a buddy that can bend and drill steel) or pvc. You can paint the pvc and it's ok, just use paint that will be ok with the high temps. If you seal everything properly and use the right size air filter and make sure that everything fits together properly, then your home made intake won't have a problem. But if you don't pay attention to detail then yes it is possible to get water in there, but just do a good job and you won't have to worry about it.

you can get some water repling filter covers from K&N they are also used for sea-doos and watercraft on the exhsust i think as a flame opresor/keep the water out but they sell them with their CAI kits... it could just be an extra layer of protection...

just use the same diameter as the intake manifold

Yeah, my airbox set up is pretty ghetto, if I do say so myself, and I do.

well, i was thinkin more stock airbox w/ K&N drop in rather than cone filter. I just wanna create a better, less restrictive "snorkle" to replace the crappy stock one. Its gonna go down to the brake duct, i just was wondrin about issues of sucking in too much water. But i guess that if i do keep the diameter the same size as the stock airbox inlet, it should be fine.

i'll most likely try to copy the airbox "fogging" method as outlined somewhere on the logun.org page. Its there somewhere at the bottom i believe, and its an interesting read, but i don't feel like messing with drilling the bottom of the airbox out.

intakes are so confusing. as soon as someone tries somethin new, there are 10 reasons as to why another method is better ... and of course they all back theirs up with some form of a dyno sheet ... figures.

thanks guys

so what exactly are you planing on doing? If all you want is a K&N filter then just take out your filter and put one it. You won't notice a difference though. I've got some kind of fliter setup ( I don't know what it is, I'll post a pic after I clean the filter), It looks like the airbox was just removed and a conical filter put on the end. however it does not look like any K&N filter that I can find on their site and it has some kinda braket to hold it, but no heat sheild. Seems to work ok though.
