I removed all that crap.. on my 07 STI there was this little black box that one of the hoses from the pump went to that was wedged between the intake mani and the motor and took me over an hour to get out.
Not sure how much it all weighs, but it does make the right side of the motor cleaner looking!!

I took out my pump and one of the valves. I couldn't get to the other valve with my tools (limited selection). The pump weights about 5+ pounds, the valves are about 2 pounds or so apiece. Then there's all the associated tubing and whatnot.

Yes, I removed the entire deal on my car. If I remember right it's around 10 pounds.

Dave, I just installed your block off plates last night and could only find the LH side valve and I blocked it off. I have an 07 STI, where can I find the valve on the RH side of the car.

It's near the uppipe. If I remove the bottom subframe (which I did for my swaybar install) I can see it, but it's really down in there. If you follow the tube with the foil corrugated tubing over it than comes from the valve, the other end goes down around the engine block and terminates on the head.

I cannot even find the valve on that side. Do you have any pics you can show us?
Can I just remove the valve for now on that side and plug off the tube until I get to change my up pipe and that time I can remove the tube??

The two valves are both on the driver side. The valve that feeds the passenger side is slightly under the intake header. You can plug the tubes. That's what I did for now.

I will have to take another look and see if I can find the tube leading over to the passenger side valve. I looked several times last night and did not see anything but I still have the stock up-pipe, turbo, and all the heatshileds so maybe that's why I cannot see that damn thing..!!!

Are we 100% sure the 07 STI has 2 air pumps? I do not think so..
I looked and looked and there is not a line that runs from the drivers side air pump or air valve to the passengers side..
Can anybody confirm this?

Also, is used Enginuity to edit the air pump removal codes and used ECUFLASH to flash the ECU..

What is the point deleting this system except for 10 pounds weight reduction??? (If the car has no cats at all...)

I wouldn't mind an answer to this as well.

Is there any benefit to this? 10 lbs? so what. I mean really....so what.

Better throttle response..I am all over it.

more HP...I am there.

Sounds neat...works for me!

10 lbs? meh....

Its not just about the additional 10lb weight loss. Its about the engine bay clutter. The more unecessary contraptions and tubing out of the way, the less congested the engine bay will be. Under hood temperature will drop. Plus it will look alot cleaner...

It helps to declutter the engine bay, reduce weight (front end is already heavier than the rear). You will get some CELS's:

P01491
P0223
P2431
P2433

Please excuse the cell phone pics:

I will get some CEL's....well that is reason enough right there to remove it....

I don't really care about the engine bay clutter. If it was an issue I would be making up some sort of stupid shroud for the entire engine.

You can't see it in the pics, but all of that brackety and some of the tubing/connectors were removed as well. I cleaned up the left side too (of other wires). Mike @innovative tuning is making me "custom" maps. Basically it's a copy of my current map with the CEL's shut off for $20.

Here are some pics of our delete plates installed on a customer's sand rail motor (an '07 I believe):

Driver side valve/etc = easy
Air pump=easy
passenger side=!!!!!! (I couldn't get it off with my tools). the uppipe is kinda close. So, I removed everything I could and block of the hose.

You'll need a "custom" map. Mike an innovative tuning is making me a map for $20. I simply e-mailed the codes I need deleted and he'll e-mail my maps back.

for those wondering, my 07 STi engine does not have a solenoid on the passenger head...



here are other photos of the pump which is almost all the way removed... just need to cut up and pull out the plastic reservoir sitting underneath the drivers side intake manifold... and i'll be using the flange that i took off to make a blockoff plate for the drivers side and reuse the metal gasket and bolts from the original.

to followup, i found out some more info that 07 STi owners will want to know... and this applies to 07 STi's specifically (possibly 08+ but i dont know yet...).
the atmospheric pressure sensor is integrated into the valve for the air pump, so removing it will cause an error in the way the car reads atmospheric pressure and as a result it will cause an error in the way it reads manifold relative pressure as well, throwing things off across the board.
my logs were only showing 11 psi max (manifold pressure) because by removing the atmospheric presusre sensor which is in the air pump valve, it was throwing an error and defaulting to 21.76 psi instead of 14.7 psi.
so... solution was to replace just the valve itself. i kept the blockoff plate on the head, i did not reinstall the air pump itself, just the valve unit using the black bracket that it came with to secure it in teh engine bay. once that was bolted down i plugged in the connector clearly shown in the photo and now all is well... atmospheric pressure works properly and as a result manifold pressure works as well.

silver unit pictured below is the valve, black connector on the top is the wiring. both were reinstalled. the atmospheric pressure sensor is integrated into this one way or another. black hose coming off the left was not reinstalled, and hardline that leads to the head was also not reinstalled.
