Shipping was a little slow but I’m satisfied with the overall experience
Really good and my horns are 10 times louder than before
I ordered this kit to upgrade to 1/2 inch from 1/4 inch air line as well as a 1/2 inch solenoid. Let me tell you, my horns don't even sound like the same horns. Slightly deeper and a LOT louder. Definitely woke them up.
