yeah i know..but theres still the fender cover that covers infront and underneath it..so the filter isnt exposed as it is in the picture..soo its got some protection from splashing, but yaa now i treat puddles like landmines n stay away :cool:

yeah its defeineltly functional :) and yeaa i didnt want to goo with everyone else well not everyone but the majority of ppl and just put it under the hood..where its still gettin lots of hot air from the engine..this way im gettin alot cooler air..and it just sounds sweet :) haha

Nice setup man, Im not very parcial on the filter placement but dont they make a kinda outer filter that says it keeps out water and stuff? Might be a good investment cause wet filter=bad air flow

yea losta companies make screens that go over the filter and filter shields that go around the filter... not sure how effective they are but they do have them.

while we're on the subject... with a turbo setup I have seen alot of people with open turbos (ie. no intake or filter)... is that good or bad? I'd expect it to be bad but it cant be that bad I guess if people do it. wats the word?

Unfiltered air going into a motor is allways bad, it carries in small particals of dirt, pollen and other small airborn agents. This will cause ports to get dirty and restrict airflow as well as letting particles into the combustion chamber to scrape the cylinder walls.

Yeahh or you can do what im doing and buy a bypass valve that as soon as it senses water it shuts off the air supply...stalling your engine...but would u rather stall, or be hydrolocked ? :thumbsdow

haha thanks...yeaa all i needed was a 45 degree bend, 18'' straight pipe, and then a 90, and one silicone cupler and about an hr tops of time :) all in all it ran me about 200$ for parts and filter

Not bad at all, cheaper than buying that IceMan model at least, and definitely as effective.

But you still got nothin' on the $4 short ram. :P

I opened my hood a couple weeks ago, and noticed that i had 4 huge freaking cracks in my intake hoses. The air box was really doing nothing. So, i ripped the whole assembly out, salvaged the elbow bend that was still ok, and slapped a $4 ricer cone air filter on it.

It's about 8 inches long, and makes loud sucking noises. I'll take pics sometime this weekend if i remember. It also makes that cool "CHAAA" noise when you quick blip the throttle from idle.

that was 200? nicely done but damn


i had to relocate my afm , bore out and hammer a hole, buy a hole saw, buy jigsaw blades, air filter + adapter plate , piping , couplers, and got some carb cleaner to clean out everything and i ended up at around $90-120, and mine is a sorta ram air style, my filter sits behind the grill, and its not in the engine bay its in front of it, ill have to take a pic

My total is only about $50. the air filter ran me about $25,I used 2" stainless exhaust tube to run to the fender and a 90* bend peice of 2" exhaust tube $15, a rubber 2" to 2" hose connector from Lowes $5 and little things like clamps and such...I'll borrow a camera so you can see mine.

EDIT: O and ads, I feel like this CAI has takin alot of my bottom end power..do you feel the same with yours? maybe im just crazy.

I know with my short ram, i lost some bottom end power... made a noticeable difference, but it did make a really noticeable difference in top end.

Sorry, i ran into that problem, too... I tried to just tape it to the front of the filter, and it made the car misfire like crazy. I just drilled a hole in the bottom of the tube, and plugged it in there, and misfiring went away.

you might use a pressure segment in the hose. What you have done is replicate a wrx cia, but they use the pressure relief in case they drive into a puddle.

just an update, CAI working great, driven in some hardcore rain and no problems, filiter stays dry as a bone in there :) and pretty clean too

Hookecho
11-23-2006, 04:04 AM
glad to hear that. looks real good too! i went another direction with mine and put the filter in front of the bumper where it could pick up the coldest air possible. i had to relocate the coolant reservoir to the other side of the engine bay. i installed a smaller filter as a bypass valve to prevent vapor lock.

Now since you guys have made a CAI im gonna be doing the same thing, making one of my own. but im thinking it will be a little more complex then that. Im going to try and go for the center of the front bumber, mabe creating my own 4 inch deep box and running the pipe back. or creating a tunnel ram set-up for it. ill be doing this within the next month so ill show pick when i get it done. Also and idea for putting a scoop on the hood and routing my piping directly above the engine, pulling the air from the scoop? idk but i have to settle for one of em. any added info or ideas on the project would be appreciated. if you do add to this idea please email me at contradictions.conflicts@gmail.com that way i know i got your 411 on my new project.

05-05-2007, 06:05 AM
one more question guys, what would be the best size piping to do this. Initially i was gonna go with 3 inch, but everytime i read something these people are using 2-2.25 inch piping? what do you think?

That is a massive no-no. The turbo's fins spin at 100k+ rpms. Any tiny piece of debris will destroy your turbo.

Theoretically your intake pipe dia should be the same as your exhaust pipe.

worth it? Should I fabricate my own from the examples listed here?

I noticed there are two diff prices. $49+shipping for ones that come with a K&N filter, and $16+Shipping for ones that come with a "high quality" filter.

The only thing I am worried about is the fact, it is so close to the motor that it will be just sucking in the heat.

geebes
06-10-2007, 10:10 AM
Hells no, its not worth it. Just put a cone filter on what the car has now and its the same. Plus it will suck in the heat from under the hood. cold air or stock air box w/ k+n filter are your best bets.

Theoretically your intake pipe dia should be the same as your exhaust pipe.

Intake air is much cooler, therefore more dense, so you can get away with a smaller intake diameter as compared to the low density high volume flow rate of exhaust.

True, I was just poking at the trend these days to have a 3" intake pipe, silliest thing I've ever seen.

Ads28
07-15-2007, 05:47 AM
nooo not rad hose , the place didnt have any 45 aluminum pipin left..soo i had to use a 45 degree bend of the silicone cupler...its the same silicone cupler used to join to straight pieces together...that piece just happened to be the only 45 piece they had left

Got mine all done. did it for about $70. Everything can be bought at AutoZone except the silicone couplings. I got those at Bahn Brenner Motorsports for $25 shipped. They have the best deal of anyone I've seen and got them within a week of ordering. I did 2 1/4" piping and couplings, and the couplings do not give very much. The pipe I got was flared on one end to slide another pipe in, but then it is a pain to get in the silicone. it was also a pain to get it on the throttle body but if you shave just a bit off the inside edge then it slides on pretty easy. And it sounds real good. :)

Izzy
06-20-2010, 07:07 AM
sry to revive an old thread, but i heard the best CAI is the one in your fender. and if you think about it, it might be tru. ive got my filter at the bottom of my engine so it picks up the coldest air possible you cant get any colder air then wats outside. but think your air has to travel all the way up that pipe in that time wouldnt it warm up? where as a filter in your fender has a much lower distance to travel so it would stay colder that and the inside of the fender would act as a heat shield.

Hookecho
06-20-2010, 05:19 PM
in reference to heat soak the shorter the distance the air has to travel the better. it's also better for throttle response. i also had my cai run to the bottom of the engine bay.

you could just insulate the cai.

Izzy
06-21-2010, 05:11 AM
exactly my point. so there for the best CAI would be a fender CAI correct? as its the shortest possible distance from the filter to the TB and it gets the coldest air
