I am purchasing an SRT Intake from a fellow CL member. It comes with everything but the installation instructions. Can anyone direct me to a proper link or got a copy of a manual?
btw, I looked at the DIY section and Carbongs did a great write up on it. However, he's got an 01 GS300. I need an install manual for 98'-00' GS400.
Thanks in advance...

Dirty and stock engine bay

Taking off the engine cover and intake plumbing



Covers and pipes off

Had to transfer the stock mass air flow sensor over to the new pipe.


Heat shield and Mass Air Flow Sensor adapted pipe installed

Vacuum lines installed

I just put mine on yesterday, it was allot more easy than I thought, even though I don't like to solder. I do have one question though Is it meant to only use that filter because I got mine from another cl member and mine came with two KnN filters,(one small cone-new, and one large cone) and also in the box was an AFE filter but its black not orange like the one pictured above. Right now I have the large cone in there, but I'm going to clean the two that are not new. So which one is best to use?

Hey Carbongs,
I got the SRT installed this weekend. It seems like the car is getting stronger as I drive it more. Also, is there anything else I need to do? Reset computer or anything?
The guy I bout my SRT from say's :
Glad you got it hooked up. The computer slowly recalibrates after 200 miles or so. You may need to dump the memory if you want the power back. Some people were running relays to kill power to the computer while the car is off. It onl needs to be off for 30 minutes to reset it.
What exactly did he mean?

Hey Fonz / Carbongs,
Thanks for the info.
I was'nt sure I had to reset the ecu again. I figured I had the battery unplugged during the ECM wiring, I thought that was reset at that moment.
I'll just unplug it again...

Wait you said it was powdercoated! Cool - did they do the insides?
