What is the black box between my air filter housing and throttle body?
Motor Vehicle Maintenance & Repair Asked on December 22, 2020
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?
One Answer
It's basically a tuned box that serves to reduce intake noise.
Think of it as a muffler for the intake.
