Iridium Spark Plug 1 pc NGK96220 SILZKGR8D7E for Audi Porsche 4.0L V8

Maximum ignition efficiency for high-performance V8 engines

The premium NGK Laser Iridium series spark plug is specifically designed for boosted 4.0-liter V8 gasoline engines (including EA825 modifications) installed in flagship models of the Audi and Porsche groups. The use of precious metals in the design allows the element to operate stably under extreme temperature and mechanical loads characteristic of high-power sports cars and crossovers. This ignition system component guarantees uninterrupted spark formation, optimal combustion of the fuel-air mixture, and minimization of misfires at any engine speed. Thanks to the reduced voltage required to break through the spark gap, starting the power unit at low ambient temperatures is significantly facilitated.

Innovative laser technology and design advantages

The internal potential and durability of the NGK SILZKGR8D7E spark plug are due to the use of advanced engineering solutions and specialized materials:

• Central electrode with iridium tip — ultra-thin conductor, laser-processed, has the highest melting temperature, erosion resistance, and ensures pinpoint centering of the spark discharge.

• Platinum pad on the ground electrode — prevents premature wear of the opposite contact, maintaining the original technological gap throughout the entire service life.

• Trivalent metal coating of the body — chrome protective layer prevents the development of corrosion processes and eliminates the burning of the threaded part to the aluminum cylinder head.

• Five-rib ceramic insulator — special geometry prevents spark breakthrough on the outer side of the plug and minimizes current leaks under high system loads.

The high thermal conductivity of the copper core, integrated inside the central electrode, effectively dissipates heat from the combustion chamber, completely eliminating the risk of detonation or pre-ignition.

Full specification of auto part compatibility by brands, years, and models

Regular replacement of spark plugs in accordance with the manufacturer's technical regulations helps reduce the toxicity of exhaust gases and protect expensive catalysts from unburned fuel residues. The elements are supplied individually in original packaging, ensuring complete preservation of the precision gap and ceramic coating.
