Default weapon r intake help

Hey. I just installed the weapon r sri for my 07 2.5i.

I cant say that im very impressed with this $225 intake. it was missing parts.


I was missing the vaccum cap to close off the left side PCV rubber hose. So I used a toothpaste cap and shoved it inside temporarily...


Ok....so the left side PCV house is supposed to be capped, right?
the right side pcv hose I installed into the second 3/8" intake pipe piece .


The other hose piece that was hooked to that little sensor I plugged into the first 3/8" intake pipe piece.

I didnt have to use the 3 way vacuum splitter. Did anyone have this trouble? Please only reference my car year.

Do you mean the breather hoses that come from the valve covers? You shouldn't really block off one and not the other...just get a T fitting from home depot and put that in parallel with the right breather hose going to the intake...

ok....what hose was I supposed to cap off? it said "use vaccum cap to cap off port on pipe closest to filter end of tube. DO NOT USE THIS PORT FOR VACCUM.

the picture only shows one pcv hose being used.

Hmm... i have the same setup and same car as you and i never needed any vac caps. One of the welded on fittings is attached to the sensor that was originally attached to your OEM airbox via supplied tubing. The other welded on fitting should attach to the 3 way splitter with a short piece of supplied tubing and "T" off to your valve covers. I never plugged anything and dont remember them saying to do so in the directions but im not one for directions usually. Anyway, I have had no problems and no CEL's or anything like that. Want a picture? I'd be happy to snap a couple and post em for you. Let me know.

I stand corrected but ****, i didnt get any nice directions with pictures like you did. Mine looked like someone wrote them on a typewriter. Hmmm.. mine seems to work just fine. Those are some confusing directions. maybe a semi angry phone call is in order?

K, heres the pics... the first one is the whole thing... the second is the 3 way splitter and I have the tubes going to the drivers and passengers side valve cover breather fittings. the third is the sensor (dont know what it is "sensing really") attached to the other weapon R fitting. guess this is wrong though according to their directions. if you call them, post what you find out since I want to make mine correct if it isn't. thanks.

Thanks for the pictures....yours seems to be installed correctly-regardless of what the instructions say. Im going to call these people up tomorrow and bitch them out, for there poor instructions.

If you think about it, whats the point in blocking off any of these hoses? They were all hooked up to the stock box, and you hooked them back up pretty close to stock positions.

I'm no expert, but i dont think plugging holes = good thing. I've never heard of blocking off a vaccum line; that seems just plain wrong to me but like i said im no expert.

yea don't plug those lines, cause they are not vacuum lines, they are breather lines, and if the engine can't vent through those lines, it will find another way to vent, which is usually blowing out a gasket somewhere.

I called them. They pretty much admitted that the directions suck. The vaccum port refered to in the directions is on an older intake design, were there was a third vaccum port near the filter.

The picture is not right either. It shows only the right side breather tube hooked up not the left!!!

I hate to tell you i saw that intake for $150 somewhere also IIRC. And the injen CAI is only $189 plus shipping. Not sure who these numnuts are you bought from. Oh well, you will figure it out, intakes arent TOO compicated once you get the idea.

You are right the weapon r is $228 shipped (my mistake) but with "ram air kit" whatever that is.

http://www.erzperformance.com/product_p/secret247.htm

And the Injen is $182 plus shipping.

I never saw anyone ever GET the weapon R but i always wondered what the ram air peice was. Probably a cheap way of making it a CAI.

The ram air thing is a little pipe extension you stick on the end of the filter (see the center section with the protruding circle?) and I think it goes to either the fender or the hood scoop thing that some subaru's have (my Legacy has one). I *dont* really think it does much since most of the filter area is at the sides, but eh...it's weapon R :shrugs:

Seems like it would help but i dont think thats true ram air right? It would be interesting if you could make it reach the hood scoop though.

a friend of mine said something about ducting from an under car scoop to that circular flange on the aircleaner but that would be a lot of work and probably not for much.

That would work.. I assume you mean stock airbox? It would be really easy from the foglight pop out hole. It looks a bit ghetto to pop the cover(s) off but i covered mine with back mesh and it looks coo.
