It's super easy to do...
You are basically making a snorkel from your air box to your driver side fog light. This allows your engine access to more and cooler air. I am merely giving you a basic idea but you don't have to use the exact same things I did...
I used/did the following:
4inch ducting (same size as your dryer vent)
Something to mate the duct to my air box
I cut an appropriate sized hole in the air box ENSURING that the hole was below the air filter
I mated everything up and tied the end of the ducting to the foglight |
