High Performances Spark Plugs

How a Spark Plug Works:

The basics of a spark plug is that it must perform two primary functions.

  1. To Ignite the Air/Fuel mixture
  2. To REMOVE the heat out of the combustion chamber

Spark plugs transmit electrical energy that turns fuel into working energy. A sufficient amount of voltage must be supplied by the ignition system to cause the spark to jump the across the spark plug gap, thus creating what is called Electrical Performance.

Additionally, the temperature of the spark plug's firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called Thermal Performance and is determined by the heat range of the spark plug.

It is important to understand that spark plugs CANNOT create heat, only remove it! The spark plug works as a heat exchanger, pulling unwanted thermal energy away from the combustion chamber and transferring the heat to the engine's cooling system. The heat range is defined as a plug's ability to dissipate heat. The rate of heat is determined by:

  • The insulator nose length
  • Gas volume around the insulator nose
  • Materials and/or construction of the center electrode and porcelain insulator

Now to the actual function: As the Ignition is triggered it sends the spark through the rotor, to the cap, down the wire and then it jumps the gap of the spark plug, a spark kernel is created that ignites the air/fuel mixture in the combustion chamber. Proper timing of this spark is not the only concern as described above. You must have the proper heat range as well as the correct gap.

Exhaust For Subaru Impreza WRX STI 2003-2004 Car

Image
The HKS Carbon-Ti catback exhausts are exclusive Special Edition HKS Hi-Power catback exhaust systems . Also referred to as the HKS Carbon Titanium Hi-Power catback exhaust, these exclusive versions of the HKS Hi-Power catback exhaust consist of a carbon-fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping for a stylish and aggressive look. Each HKS Carbon-Ti catback exhaust looks as good as it performs. Inspired by GT racing in Japan, HKS developed its Carbon-Ti catback exhaust system with features found on racing exhaust systems. The HKS Carbon-Ti catback exhaust series incorporates a race inspired offset muffler and piping design, eliminating unnecessary bends for the straightest exhaust path. This less restrictive design allows the HKS Carbon-Ti catback exhaust to have greater exhaust flow and less back-flow pressure, enhancing higher-PRM power gains. The HKS Carbon-Ti catback exhaust system can be used for both turbocharged and naturally aspirated

Subaru's Car Intake System Design

Subaru's Car Intake System Design The following is an opinion on why different year model Subaru's react differently to modifications to their intake system . Primarily we're focusing on the late model Subarus which used either an air-flow system (up to 1999) or the speed-density system (2000+) in the North American market. Before we discuss the technical details of the Subaru Intake System, lets first get familiar with the two ways Subaru has used recently to measure air flow. The first method discussed is MAF Sensors which were used on all late models until the 2000 model year. From 2000-on Subaru has begun using a speed-density system which primarily relies on a MAP sensor. MAF Sensors Mass Air Flow (MAF) Sensor is used by the engine control unit (ECU) to determine the weight of the air going into the engine. To do this, Subaru uses a cylinder shaped sensor mounted securely to the stock air cleaner box behind the passenger side headlight assem
