I only say MAFv table rescaling is necessary because in a MAF based vehicle, anytime you change the intake in any way (especially increasing the diameter of the pipe) you will affect fueling. weather its enough to do damage all depends of the specific scenario. if you are running lean due to an intake and you lose a vac line or a gasket, you will be even more lean. and its easily possible to be lean enough to do damage. Not to mention all the power you leave on the table.

I noticed when I was installing this that the most it did to change the setup on my 08 was to replace the torque box and the rubber tubing with smooth piping. It really didn't change the diameter of the pipe, at least not the piece between the airbox and the torque box.

I tried another experiment before I did this mod. I replaced that rubber tube between the boxes with a pipe that had a smooth interior. Then I replaced the torque box with this hybrid setup, and it wasn't till then that I actually noticed some gains, mainly in low end...

Am I missing anything? I'm blond so if I'm being a nube that's why...

You do realize your short ram is a bad idea, right? The codes are an example of that. They throw a code once they peg 20%. If your adjustments to the intake pulled that down to 19.9%, you won't get a CEL but you'll still have a problem.

Also, you have no way of knowing wither or not you're knocking. Unless your 08 is staggeringly different from the 06-07 (and it's not), you're knocking like a mofo.

Don't threadjack

And the AP won't do anything the open source tools can't and the AP will cost hundreds more.

I'll sell it you mine if you pay for shipping and stuff.
Or you can go to autoparts store that link points to and look for a 1997 i think subaru impreza intake.

But PM me if your interested I took mine off. Cause it made things worse.
Just FYI.

I received some communication about the intake no longer being available at that online store. Dang! It was perfect!

Here is the info for the intake.

1998-2001 Subaru Impreza - Kool Vue Cold Air Intake

P/N KV4801073

If anybody finds a source for this intake, PM me so I can update the instructions.

Check this one out: http://cgi.ebay.com/ebaymotors/2000-...Q5fAccessories

not too bad for 15$ (shipping cost more than the part itself haha)

Thats close. Looks just like the ebay intake I first tried. It will work, it just takes another hack to get there.

Probably a mixture of fantastic marketing and superior welding skills.

So, have we decided this is no longer a good upgrade? Unless you remap the MAF? I'm sorry if I missed it, but could someone post some very clean cut instructions on how to accomplish this (programs, cables, directions, etc.). I'm just lost with the argument over what program to use.

I successfully installed this hybrid intake in my '06 2.5i. The install was pretty smooth, considering this was my first attempt at doing any kind of modification of my car; I figured it was a good way to cut my teeth and learn the ropes, both mechanical and ECU-ical

After rescaling my MAFv everything seemed to be running pretty smoothly; I noticed a little knock in first gear at low engine speed when starting to move from a stop from the knock sum and it sounded great. My only complaint was that I would hit some resonant frequency of intake and it would rattle against a bracket on my firewall since the install on an '06 was pretty tight. After more forum prowling and tons of reading I made a couple of road dyno power/torque graphs that show (providing my data is correct) that I was losing torque and horsepower with the hybrid intake compared to the stock setup. I have a post for that, with data, in the works (got to get to my 3 legit reply limit first, since I'm a newbie).

I'll be interested to see your data as you're the first person out of probably 75 now that has seen any losses at all.

Interesting... that may suck for you 08 guys. If a CAI/SRI won't work because of resonance, and a hybrid won't work for some other reason, you guys just may be plain old screwed.

Since when does kartboy make crank pulleys?

That makes me a sad panda. I've been doing a good bit of research on this and was thinking of making it also my first mod. I guess I'll wait a bit until someone posts up some data. I'll let the data do the talking

Would it be because of their stupid lean conditions?
