why would they leak because of a sri? They leak because you redline your engine 2 much, a 2.5i isnt technically a performance vehicle. Stop racing hondas pizza boy and find another way home.

Hello, I am new to the Subaru world, but not to cars. I have read a lot of this thread, but at some point it just gets to be gibberish. I was wondering which one of these kits: http://www.cosmoracing.com/productin...d=226&pid=1206
http://www.2kracing.com/Product/17545.html
http://www.2kracing.com/Product/2110884.html
would work for the hybrid kit on my RS. If anyone knows the answer I would really appreciate the knowledge.

Cosmo sounds familiar, I believe many started with that.

First thanks to willarty for the write-ups. As someone new coming into this, it is nice to see a problem resolved before taking the tour of bad mods.

I have a 9-2x 2.5i and am looking to lower intake temps and maybe get a bit more growl out of the engine, so I am working on the hybrid intake.

My question is this. I have all the parts to do the WRX mod with the air funnel (already installed mismatched to the snorkus) and the WRX snorkus. But I was wondering if anyone has simply twisted the front most "horn' of the snorkus to pull air from the fenderwell rather than going back into the engine bay?

I think the WRX funnel is better at getting cold air than the damn thing in the 2.5i that pulls air from the engine bay, but it still sits on top of the radiator. How much of the snorkus is needed to get the resonance to keep everything in check with the MAF? If I keep the whole OEM piece and simply modify the front most "horn" is this enough?

TIA!

I think the part you're referring to would be okay to modify, I would think that the tube to the air box and of course the jug are what's important to its operation. I think what you want to do is possible, but if it was me I might still opt for the WRX funnel since it's a higher air pressure area so long as the hood insulation (and maybe grill) are modified so as not to block it. Others might feel differently.

Any suggestions for an intake that fits well as a hybrid on 08-11 imprezas?

I am considering the hybrid intake mod for my 2012 Impreza Sport 2.0L as well. Anyone tried it yet?

I know this write up was started a long time ago but I just want to say thank you for taking the time and posting it!!! I just purchased a 05 impreza rs wagon and I was planning on doing a Sri mod....thank god I stumbled upon this.....

I have 1 question though....

I had a 96 maxima before and I was able to find a coned filter that fit right into the stock box. So the top half of the box was off and I left the remaining parts there thinking I could get some cooler air since the stock set up ran through the fender and had a little scoop right by the hood to get air.....also it gave it that pop charge sound when you hit the throttle.....not sure how much difference it made if any because I didn't have a way to measure it.....

So would I be able to do the same concept with the subie? Would that cause problems? It would basically be a hybrid set up except putting in a conned filter inside the stock box...

Sounds impractical, I'd sooner drop in a K&N panel filter (which I don't like because they dirty the MAF anyway, as do cone filters). It's probably not the shape of the cone that lets more sound through, but the nature of the filter design.

I've actually seen someone do that before, they just leave the dam and half of the airbox. I'm not sure if that would do much. But i believe by doing that, you take off the Maf sensor. So that will most likely be a problem.

And i would not really add a K&N filter. I've ran it for a couple years, and no problems or anything. My MAF sensor was fairly clean, but i couldn't live with the fact that there were bigger particles of dust going in. You can always take my kn panel off my hands, its been in a box for a while. Hasn't been cleaned tho LOL

By removing the top half of the airbox, you're letting in air that isn't going through the resonator pipe in the fender...

I recently built a real sonofabitch of a hybrid engine (2.5 block, 2.2 heads) and have been having an issue that felt like a timing or fuel delivery concern. Long story short, I replaced the cut up snorkus and the car runs like a champ now. Being airbox MAF, I'll probably just incorporate a hybrid type intake for comparison's sake, and call it good.

KEEP YOUR SNORKUS!

alright i guess i have to be that guy, alright i have a 2007 2.5i Impreza, i'm running a Cosmo Racing SRI with a k&n cone. Now according to what i'm reading here SRI's cause the engine to run rich with black smoke and such. 1. I have no black smoke what so ever, 2. the only think ive noticed is a drop in gas mileage, but then again gas mileage on my impreza has always been iffy. I know for a fact that if u continue to run rich it is not the end of the world. You may mess up your cat and lose more gas but all in all thats about it. I mean i have temp issues here and there due to my SRI sucking too much hot air from the engine bay, other than that no problems. I still have the snorkeus inside the fender, everything else stock was removed. So i really don't see that much of a huge problem going on. If i was running lean it would be a different story but it's A LOT harder to tell if you're running lean vs. running rich. So basically i'm still completely lost with these SRI/CAI problems. I am considering converting my SRI into a hybrid though, for some reason i feel more comfortable with a panel filter. Any input would be greatly appreciated.

Oh P.S. K&N filters are not bad filters at all, u guys sucking more dust must not be keeping up with oiling the filter, the oil is what traps the dust and dirt and really u only have to worry about the dirt u can see. If u keep a k&n oiled you will be golden. But then again all filters have their pros and cons. It comes down to preference

That's because your tune is keeping you in Closed Loop in the region where this problem happens. So rather than hitting something like an AFR of 4 and stalling, you're only kitting something mildly stupid like an AFR of 8 or 9.

Bore wash isn't the end of the world but it is the end of your engine.

That's just because you don't know enough to know where to look.

In fact, you have to worry about a lot more than the dirt you can see. This issue has been studied experimentally and properly documented by several people. In all testing, the K&Ns let through considerably more abrasive dirt than paper filters. Additionally, you get no more air into the engine. So you're spending a lot of money on the filter, reducing the life of your engine, and getting no more power. The only thing you're getting is a reusuable filter. If that's what you want, just get a dry filter made of the Donaldson nanofiber material.

Incorrect. This will also allow him to place a K&N sticker on the car, which is good for 5 to 7 HP.

I bought some proper MAF cleaner recently, $8 for the can but you might as well stock some sometime. Purolator is a quality brand, they supply the OEM branded air and oil filters (at least they did, not sure about the present). The only significant airflow gains on the intake without spending bank are going to be eliminating the accordion section with a hybrid setup and getting high pressure from the front of the car to enter the airbox if you have an older model. Exhaust will give more gains (I noticed some just from putting a WRX muffler on my Legacy L). Cams are an option but valve springs may be required.
