I have read about the ISR mod. THis is related to the V6 3.0 engines.
I have 2 questions.

1. if you are standing in front of your 4Runner/Pick-Up what is the two boxes to the left of the air filter? on it on top of the other. What do they do? Are they needed? What are all the hoses that run into it for (2 run under the intake manafold)?
In the link below is the two thing that I am talking about...
