Set of 4 Bosch 96339 Iridium Spark Plugs for Lexus Nissan Scion Toyota Citroën Peugeot

Stable Spark Formation and Maximum Fuel Combustion Efficiency

High-tech automotive ignition system components are designed for modern gasoline internal combustion engines that require increased reliability under extreme loads. The central electrode of the ignition elements is equipped with a laser-welded tip made of noble super-hard iridium metal, which significantly reduces the voltage required to generate a spark. The thin tip ensures instant ignition of the fuel-air mixture in the combustion chamber, contributing to a smooth and even start of the power unit even in critically low winter temperatures typical for the climatic zones of Ukraine.

The use of these original auto parts provides significant technical advantages for the power unit:

• Complete combustion of supplied fuel and reduction of toxic emissions

• Optimization of vehicle acceleration dynamics due to a stable flame front

• Noticeable reduction of engine vibrations and noise in idle mode

• Facilitation of cold engine start after prolonged vehicle downtime

The ceramic insulator has special ribbing that prevents surface spark-over and electrical leakage to the cylinder head body. The metal body of the parts is protected from high-temperature corrosion and aggressive gas environments by the application of a galvanic nickel coating, increasing the overall service life of the products.

Resistance to Electro-Erosion and Extended Service Life

The dual iridium design provides for the fixation of the precious metal not only on the central but also on the ground electrode, minimizing gap wear during prolonged use. The unique properties of the alloy provide the highest resistance to spark erosion and thermal shocks under high temperatures inside the cylinder. The minimal diameter of the central electrode reduces the voltage requirements of the ignition coil, decreasing the thermal load on the vehicle's onboard electrical circuit elements.

The thoughtful configuration of the side electrode optimizes the spread of the spark bundle and reduces the flame quenching effect. This ensures reliable ignition of lean mixtures and prevents misfires at high engine speeds.

Installing this kit as part of regular vehicle maintenance regulates the following conditions:

• Cleaning spark plug wells from dust and oil deposits before disassembly

• Checking the size of the inter-electrode gap for compliance with factory engine parameters

• Observing the manufacturer's prescribed tightening torque when installing with a torque wrench

• Checking the condition of high-voltage wires or individual ignition coils

A special copper core integrated inside the central metal rod effectively dissipates excess heat from the working area, preventing dangerous pre-ignition and detonation knocks in the block. The product is supplied as a ready-made set of four pieces in rigid individual tubes, preventing displacement or deformation of the electrodes during transportation and warehouse storage.

Detailed Compatibility with Cars by Brand, Model, and Year of Manufacture

The presented engineering table of cross-numbers and factory modifications allows for error-free determination of the applicability of ignition system elements to a specific generation of a car. This completely eliminates the risk of thread or thermal gap incompatibility when selecting parts for engine maintenance.
