FAR FROM192.168.100.1 192.168.1.1 IT. There is a huge gap (about half inch), that allows hot engine compartment air to enter freely by that gap by the PCM´s edges. If you look the PCM from within the airbox from the inside (without the lid), and find the correct view angle, you could see an all around PCM/airbox gap....
Or, I am thinking now, it´s just me, and I am missing some seal? (bought my baby second hand)

If anyone could answer this, or even better, share a picture, I will appreciate it very much.

Thanks.

no It's not actually , I'll post an image later now I'm at work
