Has anyone else had air horns that stop working after a trip in the mud?  :oops:  :roll:  
Mine tend top stop but whiped off soak in WD40 and there good again.  :D 
I have noticed there is a threaded hole where it sucks in the air,
 :idea: Would Land Rover axel breathers fit into this hole and would it effect the air horns in any way?  :? 
Thanks Rich
