Perhaps for peace of mind, but it also has a lot to do with how you drive and what mods/tune you have done. Pull one plug and see how it looks. Also shop around for plugs, you can get them significantly cheaper than what the parts dept will offer. IIRC last time I did mine it ran 68 bucks plus shipping for the plugs; I look at it as cheap insurance.
