Hi
I just replaced my air filter with an after-market one. While taking out the stock air box I noticed it comes appart in 3 pieces. I removed the first two but the third piece (closest to the headlights) is still there. There seems to be some electronic component mounted to the air box with wires. I didnt want to remove it as I am not sure what it is. Please help

Cheers
Peter

 

Your replacing the air filter? or the whole Air box, like a cold air intake? lol whats the question?

 

that woud be your pcm (powertrain control module)

 

lol the whole air box. I tried to remove it today. when i was i noticed a grey rectangle shaped block with wires coming out of it. This was attached to the stock box. I was wondering what it is and if it can be removed. Thanks

 

ohhhhh. lol i guess that would be important. For you guys that have done a complete air intake replacement, did you completely remove the stock box and if so where did you relocate the pcm?

 

Hmm. Some people use a manufacutred bracket to hold the PCM on a set of rubber buffers. The K&N Filtercharger encorporates this.

 

i belive the number for gms pcm tray is 15995679 its about $10 from gmpartsdirect, but then its about $10 more ontop of that for shipping and handling.... or probly around $20 from any gm dealer

 

yah, if your doing a cold air intake, then the k*n one comes with a bracket for that computer, but if your building your own then you have to fabricate something for that

 

Good to know. Thanks all. I will contact my local dealer.

Cheers
Peter
