The BPR5ES spark plug is a standard plug size, having a thread diameter of 14mm as well as a thread reach of 19mm. It has corrugated ribs that prevent flashover and cold rolled threads to inhibit damage to the cylinder head. Spark plugs with projected tips can focus the spark further, thereby enabling the plug to swiftly ignite the air-fuel mixture and deliver an efficient performance.
NGK is the brand leader in the UK spark plug market and are the world's biggest supplier to many major car manufacturers. The main difference between the two spark plugs in terms of their metal component is their electrode construction.Spark plugs are directly linked to your car starting and are an essential engine component that should be well maintained. However, if you are looking for many features, you should go for the NGK BPR4ES spark plug as it has more features than the NGK BPR5ES spark plug. The best heat range for a plug is one that stays just hot enough to keep the plug from fouling, but not so hot that the electrodes get overheated and erode or act like a glow-plug and cause pre-ignition.
