The short answer is "No". The negative terminal of the battery is "ground potential" as is the engine block, intake tube, etc. so there is no difference of voltage potential that could result in a shock. "Really close" is not a problem...touching could, in the long run, cause a wear problem as the intake does move somewhat and the battery remains stationary when the engine is running.flee said:I finally had my TRD CAI installed. Love the performance. Then I noticed the "negative" plug of the battery is really close to the "Intake Tube" metal body part. Whoever had that installed should know what I am talking about.
My question is, during the operation of the vehicle, I mean in case or if the Intake tube touches the battery negative plug, would it create any shock or anything?
