High Performance Spark Plugs

Spark plugs are the "window" into your engine (your only eyewitness to the combustion chamber), and can be used as a valuable diagnostic tool. The spark plug displays symptoms and conditions of the engine's performance. Spark plugs are typically available in different heat ranges. The plugs that we sell on the NEUSPEED website are suitable for stock engines and mildly modified engines. Spark plugs are one of the most frequently replaced components of the vehicle. Thus the correct selection of spark plug is essential in order to maintain correct engine performance.

Spark plugs are available in different thread sizes and heat ranges. The various sizes and heat ranges are required to match engine requirements. Spark plugs are indispensable components of your Porsche?s internal combustion engine. It is where your vehicles engine derives its power through exploding gases inside of a combustion chamber. Spark plugs are sometimes referred to be flame igniters in the sense that they are used to ignite combustible air-fuel mixture. While an already failing plug does more harm than good, you might as well reward your vehicle with equally dependable spark plug replacement that re-establishes the efficiency of the ignition system performance.

Spark plugs are installed in your vehicle in order for an electric spark to take place. This spark will happen once the spark plug is hot enough to ignite the air/fuel mixture that is inside the combustion chamber of the internal combustion engine. Spark plugs are where spark plugs typically are, the spark wires run to a distributor like you?d expect in any vehicle, etc. Spark plugs are cheap - I would go with a brand name like Bosch or NGK, choosing to avoid the no-name brands. Make sure that you measure the spark plug gap (if single electrode) with a spark plug gap tool before you install the plugs.

Spark plugs are the only eyewitness to the combustion chamber of the engine and can be used as a valuable diagnostic tool. The spark plug displays symptoms and conditions of the engine's performance.

Engine and spark plug manufacturers will publish information about the characteristic markings in spark plug reading charts (e.g. Engine?s spark plugs create sparks that ignite the air-and-fuel mixture in the combustion chambers. Because the end of a spark plug is located directly in the combustion chamber, spark plugs are exposed to very high temperatures and pressures. Engines need to be ignited first before they actually start. The main function of the ignition system is to ignite the engine fuel at exactly the right time so that the expanding gases can perform their maximum capacity to work.

Detonation is most often indicated by chipping on the center electrode insulator or breakage of the ring land at the edge of the piston. Although detonation is usually caused by the gasoline’s octane rating not meeting the compression ratio requirements of the engine, detonation can also be caused by an inoperative EGR valve system (See Photo 4). Detonation may appear in only one or two cylinders, while the others do not detonate. Unlike oxygen sensors and some knock sensors (which can only retard ignition timing for all cylinders equally), PREP Spark Plugs act on a cylinder-by-cylinder basis. Detonation is easier to control with a colder plug. Unless the plugs are fouling, I won't use a "5".
