I am selling my cold air kit that was on my car. I recently changed my setup and I no longer need it. It’s very nice and worked very well. It’s nearly 4” inside diameter and definitely helps it breathe! The filter is very big and has some dents from going in the fender but it’s not going to impact the performance. I am also selling my 2.9 Whipple and my Accufab throttle body on another thread. $275 shipped with meter and housing, $200 shipped of just the kit without the meter and housing. Payment via PayPal. Please PM me with questions. Thank you!
