NGK V-Power Spark Plug Box of 4 (TR6)

NGK V-Power Spark Plug TR6 (4177) – Box of 4

NGK TR6 V-Power is one of the most widely used performance spark plugs for the GM LS engine family, and for good reason. This plug is one heat range colder than standard OE, making it especially suitable for engines that operate under heavy load, high RPM, and increased power output – such as drift, track, and performance cars.

The colder heat range helps transfer heat away from the combustion chamber more efficiently, reducing the risk of pre-ignition and ensuring stable operation at high engine speeds. At the same time, NGK’s V-Power electrode design provides a strong and reliable spark, which is essential in engines with high cylinder pressure and aggressive driving conditions.

Within the LS series, the TR6 is a proven and reliable choice that combines good durability with consistent ignition performance under demanding use. This is exactly why this model is often preferred in performance applications over standard spark plugs.
