If there's a vacuum leak the engine will suck in a bit of the aerosol starting fluid and you'll hear the idle speed change from the mixture change. Just be careful about how much you spray, hot metal surfaces, etc. You should have a fire extinguisher on hand in your garage anyways :)

Man, I remember doing that for hours when I had a boost leak on my Evo... I sprayed a little and thought I found it and then do it again and it wouldn't work and on and on... SUCKED!

it really does suck. had a msp3 and had to do the same, was very tedious and time consuming. I'm really hoping I don't have to do it again for my z.

at least there aren't as many hoses and such. We have an 09 MS3 as well.

ms3, most underrated car on the road. I loved the torque in that car, stock for stock would roll sti's and evo's no problem. went from that to the z:)

I actually came from a '10 MS3 myself with an SRI and a COBB stage 1 tune. I agree the power is underrated. 4th gear REALLY pulls hard... a shame that turbo is so small and dies off at 5500 though.

I had 07 true red ms3, Cobb Sri and stg 1 ots tune. great car, I just had too many fuel pump issues. had to get rid of it for that reason. replaced the fuel pump three times and it still never was right.

those plastic things (aka stock air intake ducts) are meant to be removed. it's impossible to fit the intake properly without removing them.

the core support is supposed to be trimmed with a tool of your choice, to accomodate the circular piping which is wider than the existing holes which are exposed once the above mentioned ducts are removed.

if the holes have been cut too big, there is no choice but to fab up a bracket for each side or wrap the piping in rubber sheeting or EVA foam. Stuff like a camping mat is perfect and cheap. I'm surprised they cut so much out that the pipes are that loose. i hate loose things in my engine bay so when i fitted mine, i cut the holes to leave about a 5mm gap around and i wrapped the pipe with EVA foam to absorb vibrations. You'd want to also make sure there is adequate protection for the a/c lines on the left side as the G3 is known to eat those pipes over time if insufficient protection is installed. All you need is to cable tie a rubber hose over the section of ac line (slice is lengthways and push it on).

cheers
