If my car has 2 throttle bodies how many cans of Sea Foam Spray should I use? [SOLVED] Asked by Rocco Fimmano F. In Alabama I have an Infinity G37. It has 2 throttle bodies. Do I need 2 cans of Sea Foam Spray?
Great question Rocco. You only need one can. A full can typically requires 6 minutes of spray time to empty. Spray one throttle body for 3 minutes, then switch to the second throttle body until the can is empty.
