These billet light weight aluminum protective caps guard against breaking the connector entering the coils. The fact that they look so great is just a bonus. The body of the coils are constructed out of abs plastic material and could get broken if bumped or leaned on, which could cause a misfire.Now you won't have to blame your mechanic or buddy for resting a wrench or other tools on the valve cover or cop plate. Although the coils are relatively inexpensive it's the down time or inconvenience we are trying to avoid. Please remember these coils are covered by a 1yr warranty against failure or defects, however breakage is not covered. Just to be clear, this is not a prevalent problem, we have seen a couple incidents over the past few years and this is a proactive measure to reduce future downtime & costs.
