New precious metal spark plugs added to NGK range


Niterra, the ignition and vehicle electronics specialist, has added another four precious metal spark plugs to its large range of NGK Independent Aftermarket (IAM) offerings.

According to Niterra, three of them are new double precious metal references that offer customers the very highest level of quality in a Laser Iridium product, promising superb ignition reliability, high resistance to wear and optimal ignition performance.

Furthermore, a single precious metal upgrade unit has been added to the product range. This Iridium IX reference improves ignition performance compared to the standard version.

DILKAR8R9HS and DILKAR6Q8 were launched in September last year. DILKAR8R9HS is following the OE business of Niterra while DILKAR6Q8 will function as a cross item for a high amount of recent Toyota applications. DILFR6N-T was launched at the end of February 2024.

Collectively, these new references cover key cars from Renault (Megane 1.8 RS), Toyota (C-HR 1.8 Hybrid, Corolla 1.8 VVTi Hybrid and various Prius vehicles, including the PHV 1.8 Plug-in Hybrid model) and Lexus (the ES and GS).

The fourth unit – ZFR5BIX – was also launched in February 2024 as a precious metal upgrade to the existing nickel spark plug ZFR5P-G, which has been in NGK’s product range for some time. It covers the Volkswagen Group brands Seat (Cordoba, Ibiza), Skoda (Fabia) and VW (Polo, Lupo and Fox).

In addition to the four newly launched plugs, Niterra has significantly expanded the versatility of the ILKR7B8, which accommodates a considerable amount of Hyundai i10 and i20 models with this previously launched IAM plug.

“Once again, we are extending our already comprehensive range of NGK Ignition Parts precious metal spark plugs to cover even more of the top models from the world’s leading automakers. These new references offer customers superb 4-wheel Aftermarket products that promise our usual high standards of ignition, performance and high resistance to wear,” said Frank Massia, director marketing aftermarket EMEA at Niterra EMEA GmbH.

Four of the spark plugs are part of Niterra’s Laser Iridium range, which has at its heart a laser-welded iridium alloy on the centre electrode and, in most cases, a platinum chip on the ground electrode. This ensures optimal performance over a long lifetime, with features including stable idle, superior anti fouling, improved fuel efficiency and lower emissions.

ZFR5BIX features a special technology, the annular gap, that prevents carbon particle deposits from blocking the ignition voltage. It also has an extremely thin laser welded central electrode that provides outstanding ignition performance.
