Set of 4 Iridium Spark Plugs NGK 90288 DILKAR7M8 for Toyota Camry, RAV4, Honda Accord

This set of four spark plugs from the Laser Iridium series is an original solution for servicing modern engines with high demands for spark stability. The NGK 90288 (DILKAR7M8) plugs are designed with noble metals on both electrodes, ensuring their operation under ultra-high temperature and pressure conditions. The use of iridium and platinum achieves maximum wear resistance, allowing factory performance parameters to be maintained throughout the entire service life.

Engineering Features of the Laser Iridium Series

The main advantage of this model is the ultra-thin central electrode with an iridium tip, made by laser welding. This design requires less voltage to break the spark gap, significantly easing cold engine starts and reducing the load on the ignition coils. The side electrode is equipped with a platinum insert that prevents metal erosion and ensures the electrode gap remains unchanged. The product's body has a special anti-corrosion coating that protects the threaded part from oxidation and "sticking" to the cylinder head.

Operational Advantages and Engine Efficiency

Using DILKAR7M8 plugs contributes to more complete and efficient combustion of the fuel-air mixture. This results in stabilized idle speed, increased vehicle responsiveness, and reduced fuel consumption. The high dielectric strength of the ceramic insulator eliminates the possibility of external current breakdown. The internal copper core effectively dissipates excess heat, preventing pre-ignition and detonation, which is critically important for protecting the piston group when operating at high speeds.

Compatibility and Applicability by Brands

The set is fully compatible with a wide range of Japanese and Korean vehicles equipped with modern gasoline power units:

• Toyota / Lexus: models Camry (engine 2.5 A25A), RAV4, Corolla, Lexus ES, NX, RX.

• Honda: Accord (volumes 2.0 / 2.4), CR-V, Civic.

• Mazda: Mazda 6, CX-5, CX-3.

• Nissan / Infiniti: Altima, Maxima, Q50, Q60.

• Hyundai / Kia: Sonata, Elantra, Optima, Sportage.

Recommendations for Selection and Use

When selecting, it is necessary to ensure the heat range (in this model — 7) and the geometric parameters of the thread meet the vehicle manufacturer's requirements. Installation should be carried out only on a cooled engine. Before removing old plugs, it is recommended to clean the spark plug wells with compressed air to prevent dirt from entering the cylinders. When installing new parts, a torque wrench should be used to adhere to the tightening torque specified on the packaging. This ensures proper heat transfer from the plug to the cylinder head and prevents damage to the threaded connection.
