Set of 4 pcs iridium spark plugs NGK 90288 Laser Iridium Spark Plug DILKAR7M8 for Toyota/Lexus/Honda/Mazda/Nissan/Infiniti/Hyundai/Kia

Set of 4 NGK 90288 Laser Iridium Spark Plugs DILKAR7M8 for Toyota/Lexus/Honda/Mazda/Nissan/Infiniti/Hyundai/Kia

The set of four original NGK 90288 Laser Iridium series spark plugs is designed for high-tech engines requiring maximum ignition precision. The model is based on a combination of an iridium center electrode and a platinum pad on the side electrode. This design allows for a stable spark under extreme pressure and temperature conditions inside the combustion chamber. Laser metal processing technology ensures minimal electrode wear, guaranteeing the maintenance of the factory gap throughout the entire service life.

Efficiency and Durability Technologies

The DILKAR7M8 plugs have an enhanced ability to self-clean from carbon deposits due to the optimized thermal rating. The thin iridium tip reduces the voltage required for starting, easing the work of the starter and battery, especially at sub-zero temperatures. The outer casing of each plug is protected by an anti-corrosion coating, preventing damage to the threaded connection. Using this set stabilizes idle and eliminates misfires typical of worn consumables.

Compatibility List by Brands and Models

These spark plugs are intended for the following gasoline engine vehicles:

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

Installation and Operation Recommendations

Spark plug replacement should be carried out on a completely cooled engine to avoid thread damage in the cylinder head. It is recommended to use a 14 mm spark plug wrench and strictly adhere to the tightening torque specified by the vehicle manufacturer. Before installation, visually inspect the integrity of the ceramic insulator. This set of 4 allows for complete servicing of a standard four-cylinder engine, ensuring synchronous operation of all cylinders and eliminating fuel detonation.
