Lightbulb MY05 Intake & Catch Cans Setup

Decided to finally take some pics of my halfy-ghetto rigged intake and DIY Catch can setup.

The intake used to be a 03 RS Weapon-R Intake which i've plugged the MAP sensor hole and cut part of it off to fit the MAF sensor adapter on and painted black to get rid of the damn blingy. Then I finished it off with a GREEN airfilter for filtration.(Cost so much less than Injen)

I then made a catch can setup which has many purposes..

One catch can (Top Right) is for the valve covers
Second catch can (Mid Left) is for the PCV Valve

Of the two, i've emptied the PCV catch can once already it was halfway full of oil.. oil that would've entered my intake manifold and given me some more headaches. I also replaced the PCV catch can with stiffer tubing so it wouldn't buckle under the pressure. (Not Pictured)

Now, the Valve cover catch can the filter is turning brown so I know that's working, and the PCV valve cover can is working since it's beginning to fill up with oil once again.

For any RS that does any kind of hard cornering or autocrossing/track I HIGHLY suggest you do this, since the forces can force oil into the system uneventually.

Here are the photo's..

OEM 05 MAF sensor is slanted to match to the OEM airbox.. you have one, look at the filter box .. Very interesting CAI Setup BTW.. and you have a CEL, how did you fit the MAF sensor in the tube?

the second pic still look kinda confusing to me, lol... is that tube at the top part of a 03 intake?

i did alot of cutting and fitting yesterday for the whole day to make everything fit...

i shaped a hole with a drill and dremal on the tube... the MAF sensor fit pretty good there.. today i didn't drove much... but till now there is no CEL light... might go out drive abit more tonight.. hope the CEL won't go on again...

now im just using a crappy cone filter from my friend... later im going to get a KN filter to replace it...

here's more pic i took just now

yup, i did the same thing prior to this intake..

you need to be careful with that MAF.. they are VERY sensitive and require adjustments when messing with the airflow, one of the reasons why i used the OEM MAf housing and tried to locate the filter like a stock location.. you may be experiencing turbulence from that bend before that MAF and the size of the tube with the MAF may be harmful for it causing your car to run lean or rich..

Looks a lot better than my first attempt. You can see I quickly just went with a prefabbed product anyhow.

Not sure how PVC would be bad, but in any event I took it off a week after I put it together.

I believe my Ganzflow is aluminum, it is wrapped in heatsink tape (something for computers).

removed the filter material today in the catch can and it works just as good as with or without. I'm emptying the can once every 3,000 or so miles, it's amazing how much oil the car is tossing into the manifold.. Incase you don't believe me.

you know, i can't help but think, all this work on intakes....I was under the impression that, atleast on the n/a engines, the stock intake was the ideal setup. I mean, I just yanked off that big silencer box and voila! I think it's better, less clutter in the engine bay, no CEL or issue of any kind, and it was all done before I could finish my beer.

And even better than that, I read that thread on intake filter tests, and I sure am glad I stuck with a paper filter and didn't drop 30 bucks on a KN just for some more crap in my engine and a cool sticker. I mean the KN box itself says it will only add 2-3hp. Maybe that power comes from the sand boring out the cylinders over time? 20k miles with a KN filter could bore you .30 over! Zing!

Nice work though guys. I hope you gained some sort of benefits after all that. You did mention track days, so maybe you're at a power level where what you're doing IS helping.

Am I wrong?

uhh thanks boss but alot of people get the k&n filter because we can clean and recharge it for alot less than its gonna cost you to keep replacing the stock one

also do some research just ripping off the silencer box isnt the best move, some people believed the stock torque box and a 3inch tube into the fender is the best

well I guess my point flew right over you piker. Maybe one of the other guys will understand.
But as to your point, if price was the only issue, I'd just make my own out of a coffee filter or something. To me the formost function of a filter is to filter out the impurities in the air. While allowing efficient flow.

Instead of me trying to explain the downfalls of K&N to you and starting a debate, you can read the test results for yourself.

http://www.bobistheoilguy.com/airfilter/airtest3.htm

There's another link out there where a kid tests about six filters with a shop vac hooked up to a ram intake. It's a pretty cool test which uses a completely different method as "bob" and still gets the same results. The link is on a post somewhere in the threads. I'll try to find it.

Just taking off the silencer doesn't do any harm.

well.... if that is your point of view and you are trying to stick it to someone that's all fine and dandy except for the fact that your statements contradict yourself and the article. If your number one thing would be a filter to filter out the impurities while allowing the most efficient flow.. that would be the K&N. In the article the K&N held its own. K&N claims the filter will actually filter within 1% of the stock paper one. It did that. So yea.. the paper one was literally microscopically different. I mean.. who's a big enough nerd on here to determine what 1% of dust is over the filter life. The author said the paper one killed power.. and he got rid of it. So I wouldn't say that's efficient. If the K & N can really make 2-3HP as claimed and filter that close within 1%.. it's the winner by your standards. plus.. I live in the middle of the desert In AZ. my car has yet to explode. I have been using nothing but K&N filters on my cars and off road vehicles.

Well I'm not exactly passionate enough about this stuff to argue. Between that article and the other one, which emphasized the inefficiency of the K&N, I simply agreed with them and went with the filter which they said would protect my engine the best. I'm in the dirt and salt constantly.
Reguardless, K&N seems to be sworn by enough to merit it's wide use. Happy?

I didn't mean to step on anybody's toes by asking a question.
