Spark plug/wire question

[Eclipse419]

Do Spark Plugs and spark plug wires make a difference in performance wise? will you gain some hp from it if so how much? i was thinking about purchasing some MSD spark plug wires 8.5mm with with denso iradium spark plugs...

depends on what condition your plugs and wires are now. i do not notice a difference when i change mine

The spark plug is quite simple in theory: It forces electricity to arc across a gap, just like a bolt of lightning. The electricity must be at a very high voltage in order to travel across the gap and create a good spark. Voltage at the spark plug can be anywhere from 40,000 to 100,000 volts. The plug also has to withstand the extreme heat and pressure inside the cylinder, and must be designed so that deposits from fuel additives do not build up on the plug. Some cars require a hot plug. This type of plug is designed with a ceramic insert that has a smaller contact area with the metal part of the plug. This reduces the heat transfer from the ceramic, making it run hotter and thus burn away more deposits. Cold plugs are designed with more contact area, so they run cooler. The carmaker will select the right temperature plug for each car. Some cars with high-performance engines naturally generate more heat, so they need colder plugs. If the spark plug gets too hot, it could ignite the fuel before the spark fires.


-Cliff Notes- Spark plugs are very important to your cars health. Cheap plugs could cause bad gas milage, lack of power, and many other problems. http://auto.howstuffworks.com/ignition-system.htm is a great source for information on ignition systems and many of its components. I would recommend you invest the money in quality plugs and plug wires. And i believe the Irradiums to be really good plugs.

I'd just go for the house brand of plug wires, in whatever premium set they sell. NGK wires are well thought-of in DSMland. So are NGK plugs- the iridiums are apparently good, but I don't know that they're that much better for the money.
