Just bought an air horn from halfords and have been looking at the wiring diagram, it says include a relay. Do i need a relay or can I plug it straight into where the existing horn connects?

Rightly or wrongly i just connected mine up to the existing wiring, works fine and has done for 18 months :)

Use the relay :)
Theres a lot of reasons but you should use the relay if only because it means you get a sperate correctly rated fuse for the compressor.
