Well, OLD or not. Most people purchase their CAI from online or local shops... not direct from AEM... the difference? These shops or stores order in BULK, say 10-20 of each CAI, they won't likely sell them all right away, so if the store ordered the kits in Jan '01 and no one buys it until recent, then the recall would be effective in avoiding a problem. Makes sense. Also, don't know when they discovered it to be a problem, but at least they recognize it.
