Bought this and decided to just use my intercooler. The demensions are 12.25"x12.25"x4.5"...Brand new, never been use. $130 shipped and paypal preferred.

Recommended for over 700 CFM
Pressure Drop: Less than 0.1 PSI. This is not a typo! Liquid/Air Intercoolers have incredibly low pressure drop.
Air Inlet/Outlet: 3.0"
Water Inlet/Outlet: 1/2" NPT
Maximum water/air pressure: 70 PSI
The inlet and outlet on this intercooler are located at a 90 degree angle for cramped installations.
Note: The water inlet and outlet on most water/air intercooles are BPT threads. BPT fittings are difficult to find in the United States, so ours all come with NPT threads. "
