NGK iriduim plug Question

Ok, Before anyone rags me to bad, I searched some but most of the post ask where to get the plug, or how much it is, or the gains after installing the plug. I am new to the utility fourwheeler world but I love it already, I had a 450r which was great but my foreman can do alot more things that I need it to do. But back to my question can I just buy this plug and install it without doing anything else to the motor. Wasnt sure if this required you to have jets or different intake or anything like that. Thanks
