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.
NOTE: 2011 MODEL YEAR TRUCKS MUST UPDATE PCV Regulating Valve to 2012-2016 model year spec to allow correct fitment and compatibility with this part
Not compatible with aftermarket LML Y-bridges that change the manifold / bridge inlet from the original factory (driver side inlet) location
