I recently purchased a 2001 Dodge Dakota 4.7L SOHC. I want to start working on my own vehicles more. But I have very little experience and this question reflects that.
Please correct me if I get anything wrong. But I believe I know what #1 and #3 are in my picture. #1 is the air filter housing. #3 is the throttle body.
What I have no idea about is #2. I can clearly see that it is in between my air filter and throttle body and is connected to both by hosing. What is it and what does it do?
