Bolt-ons are typically most everything you can do to the exterior of the engine itself. Usually, CAI, full exhaust, pulley (ies), etc. It pretty much means everything that doesn't require removing a valve cover. I always thought to include intake manifolds too but I've never really noticed any consistancy either way.
