well my car came with a short ram intake w/ AEM filter. nice looking and sounded fine but wasn't really my style.

so i read around this forum (and others) a lot to see what people had come up with. the icebox copy was definitely good info! however, wasn't finding thin walled PVC around here to make the cold air intake pipe.

i used 4" semi rigid ducting to bring air into the airbox. i have it routed like the icebox clone (going down by the turn signal then turned toward the corner marker). it was quite easy to route and install. it took a little effort to mate it up to the inlet on the airbox but was doable. here are a couple pics...



next issue was the air filter. seemed like highway robbery to me to pay $65-75 for a drop in high flow air filter for the stock box. i started looking and measuring to see what i could come up with. additionally, found some great calculation tools on K&N's website to determine exactly how much filter surface area is needed for my application.

after much searching i found a high flow air filter from a known manufacturer that would work for my project for $31.

below are pics on how i went about installing the filter. basically, i used the stock filter base to make a mating collar for my new filter and it worked perfectly!

stock airfilter in airbox:


inside view of stock filter (there is a lip in there for attaching the new filter; its hard to see but i verified it before starting the project):


peeling away the filter element to get at the base:


bottom section of filter after cutting:


remaining filter and mesh. it actually pulled out quite easy so if i were to do this again i'd try just pulling that off first without cutting:


here is the new filter clamped onto the flange left after all the filter element was removed:


finally, a few pics of it sitting in the air box. fits in nicely, its smaller in diameter and length than the stock filter (which i wanted to allow more air volume in the box around the filter):




in summary, i got a setup i am happy with for under $40 and about an hour of labor. the filter has flow capacity higher than my engine needs yet still gives more air space in the box, which was one of my goals. i also have a reusable filter for about $10 more than a plain old paper filter costs from the parts store.

 

Wow, great job!

 

:goodjob:

 

very nice :thumbup:

 

thats awesome, what part number or size is the air raid filter.

 

nice, i did that mod with a k&n filter maybe 5 years ago. still rocking it.

btw, the lip on the base that the filter is secured to looks a bit narrow from the picture, so you may want to add some adhesive or something for additional security.

 

vtec, its an Airaid # 700433

reno, lip was a bit shorter than i wanted, but after securing the filter i shook it around like a madman it held on just fine. i'll be keeping an eye on it anyway...

 

Very creative and the filter set up looks good. However, I have to say from an aeronautics standpoint, the rigid hose you have running under the airbox to down under is going to provided resistance to airflow. Probably nothing noticeable, just saying...

 

ya, i know smooth tubing would best. i would like to find out exactly how detrimental non-smooth tubing is. i've been trying to find some info (good old google) but haven't stumbled upon much as of yet.

 

Picture air taking the shape of your tube as water would take the shape of a glass. 1 it isn't really sucking in air until it hits the air filter, it is just drawing in air from the location. So with that being said the air that is getting caught in that hose is filling out those indentations, so if you had a drop in pressure during shifts and what not, the hose would continuosly contract and expand because of that play and flexibility in the hose. Whereas hard piping, smooth and solid would not have that problem.
