Review on Wolo (402) Air Max Black Plastic Trumpet Horns - 12 Volt, High and Low Tone: Powerful and Versatile Horns for Enhanced Vehicle Safety by Steven Cox

This Horn Kit is a great deal at the Revain price with no sales tax and free shipping about $8 cheaper than your local car dealer. I bought this as a second replacement for a Toyota 4Runner. Compressors are prone to rust from exposure to water from roads. This compressor looks better sealed so it lasts longer. Most Japanese cars have weak horns and this kit compensates for them. They tend to startle the unwary (good thing). Installation is simple but requires electrical wiring and the installation of a relay, compressor and horns. For simplicity, I disconnected the existing horn wire, routed the ground wire to the existing screw, and used the existing holes in the body panels.
