Notes

• Not compatible with OEM and aftermarket intakes (such as K&N) that do not use a silicone boot connection at the horn. If your intake has a built in rubber connection that slides onto the OEM horn, and is molded to the air intake pipe, it WILL NOT fit with our horn. The WCFab horn must be used with an intake pipe that will accept a 4" boot and clamp. 
• If your intake uses a Boot and two clamps for connection, our horn will work with that intake.
