I used this product on a customer's 2014 Dodge Ram 2500 Hemi to install a short ram air intake. I installed the adapter between the stock intake tube going to the throttle body and a new cone Spectre air filter that I purchased from a local parts store. The reducer/adapter worked great! The customer also loves the sound that is now coming from underneath the hood.
