BMW Repair: 2001 BMW 325i spark, 2001 bmw 325i, plug gap

Question
Do new plugs need gap set or is the gap from box OK? Using ngk plugs Getting error codes E-4, E-3, A-8, CA and Cb on code reader after putting in plugs.

Answer
I am unfamiliar with the codes you have given.Readers do give different information.As for the plugs if they are what BMW accepts type,heat range,etc they should be fine.If there is a plug gap listed on the tag under the hood then I would adjust it to that setting
