I like it! I've seen it before...a long time ago.

I do have a couple quesitons I'd want to ask the vendor though...

What's up with the tube on the side? Where does that go? And what does it look like where it connects to the throttle body?

That puppy has been on here before a long time ago. I think it was like primer light gray or some sort of pastel blue. Someone was making it but then it just kind of disappeared. Nice to see it show back up again. Definitely a different design.

Dcrawford, I think i figured it out. If you look close at the first pic, you will see that the tube comes out of the box and runs underneath the box in a j-style tube that connects to the throttle body. It looks like a neat design, but you would probably lose some low end. I bet it sounds sweet!

Exactly how is that a cai setup, all i see is a filter siting face up ? Would'nt that setup attract more hot air from the engine? Actually what would be the difference between that and running the stock box with a drop in filter and no pipe to connect to the box. Not that i would recommend either choice. Get a ganzflow, or cobb.

Thumbs up

180flipmegatron, for those with the pre-02 cars that have a hood scoop, this setup is a cold air intake.

An open intake like that will get some water into the engine...but a little is OK (think water injection, which can be good). Of course too much is bad but keeping it well oiled will be alright. Would I want that intake if I drove in Seattle? Nah. Arizona? Only in summertime.

As far as the intake tube goes...that seems kinda odd to do it that way. Why complicate the airflow that much? Hmmm....maybe to "smooth" the airflow after it has traveled through the filter, giving a bit more "smooth" throttle response.

But I would do it differently...with Bob of course.

I am pretty sure the guy who originally did that was Sean Renick. He has put lots of parts in his car that he has made himself in a pastel/purple kind of color, and that was one of them.

If the tube that runs into the "box" has a velocity stack on it it would work very nice, if it was just a tube end in there, you could see gains by adding a stack. The problem is that there isn't alot of room up there in the box for the tube to flare to a larger diameter. As far as the bend is concerned, is is less of a direction change then the sometimes sharp "J" bends that are being used for short ram intakes. Yes the bend is larger, but it doesn't force the incoming air charge to make as big of direction change.

The hose that looks like it goes to the throttle body (if I am looking at what you are) is the PCV hose. One of the three hoses that run from the stock intake to the head breathers and the split hose that is on the back of the engine near the throttle body.

cheeRS,

Greg

inlighten me on why front mount intakes(cant remember which one was made, maybe aerospeed) are rice. As from a funtunal stand point i can see possible air flow improvements. Is the idea of a fmintake rice , or the funtionality of the intake? And just so i dont get bumrushed, no i never owned one. The idea as far as an intake went seemed possible.

Have you seen how long the piping is on those things? I believe the rice accusation would be from form over function....it's design isn't really effective for an intake...

ditto it is more for looks than functionality...the idea makes sense.....rushing cool air stringt into the filter, but then it is all wasted by running about 3 or 4 ft of piping with several 90degree bends to the throttle body...hess a good loss in low end power and not much but sound.....that sir is pretty rice...

Now i know , and knowing is half the battle. You cleared up the funtionality part , that is what baffled me. Thanx

Wow, I wish I knew you guys where talking about this over here.

Yes, that is my intake. I am Sean from Renick subaru and Gravelsports. I have had this intake on my car for about 2 years now. I am finally going in to production with it because I am now 100% comfortable selling it to the general public. I have been driving eveyday and racing the car on the weekends. I have had NO water injestion problems. The filter is close enough to the hood scoop to have cold air forced into it but far enough away to have most of the water fall off before getting to the filter. I have gone through water crossings and dirt in the same day and have noticed no loss of power or conjestion of the filter. I still would recomend the use of a K&N filter so it can be easily cleaned and the oil will help repeal water.

The car in the pic is a 2002 rs with a WRX hood on it. The customer did this purely to do this intake. I origanally figured only to sell them to 2000-2001 rs's.

As to the length of the tube, I have tryed quite afew sizes before I settled with this one. There is a large increase of bottom end torque. I will be suppling dyno numbers very soon.

Like I said, I waited 2 years to bring this out. I have done everything I can to it and had nothing but a good reation from it. I really don't care if you guys think it is ricey :monkey: It works and for us RS guys it puts the hood scoop to a good use. Any way the length of the tube was an important measurement it is NOT just some filter put infront of a bumper like the front mount intakes.

Feel free to e-mail me or the vender I am selling them through if you need any more info.

Sean...I wouldn't call that rice at all. Pricey..yes(but I am cheap ) I would love to see and hear one of those in real life. Nice job on the intake, I look forward to seeing the dynos.

[rant]
If this was truly rice wouldn't it be blaze yellow or chrome?

To all of the rice slingers.....Sean made an intake that he believes in and has tried.

I don't see anyone calling Dcrawford's intake rice. (No offense intended NC) Even though it is flasher than this one.

I love that intake TMR...I'd be curious to find out how the different lengths of the intake tract effect low end tq production.

Also, could you post some pics of it outside of the car? Hopefully upside down.

I like the intake Sean.

question though, will this fit under the hood of my MY99 Legacy? I do have a hood scoop, but will the legacy hood scoop draw enough air to be beneficial?

Thanks for the nice coments guys!! The owner of the car in the pics, took pics of every step for the building of the intake. As soon as he gets back from Florida I will post the pics of the intake from ever angle you can think of.

Yes, the length of the tube does matter. The volume of air between the T.B. and the filter WILL alter the amount of power you get at the bottom end. This might sound strange to some of you, but try it yourselves. You will notice a differance. A good example is on some of GM's cars( 94-97 impala is one) they put a large box in between the filter and the throttle body. On the impala it is the large triangle shaped deal on top of the motor. If you take it off the car has a bad flat spot at the bottom end. This is the same on our cars. If the run is to small, the engine is starved for air in the begining. You can really tell the differance when you have the right compination.

Now I'm expecting to hear from some of you that don't understand this, like I said try it yourself before you speak. I did not just throw this thing together and post it for sale. I built quite a few proto types before I settled with this one and then still waited 2 years.

For those of you that are interested in ordering one, go to www.pkzero.com and Kevin will take care of you.
