NGK Racing Competition Spark Plug R7438-8 – Audi RS3 8V/8V.5 & 8Y

Overview

NGK Racing Series spark plugs are built to handle the extreme conditions of high-performance and motorsport engines. Featuring a fine-wire iridium-tipped centre electrode and platinum-tipped ground electrode, these plugs deliver superior ignitability, enhanced throttle response, and exceptional durability under pressure.

With a heat range of 8, these colder spark plugs are ideal for high-boost turbocharged engines and competition use. A pure alumina silicate ceramic insulator ensures optimal heat transfer, while a copper core and triple-sealed design guarantee consistent performance and leak-free reliability. Corrugated ribs prevent flashover, making them perfect for high-RPM or high-compression applications.
