NGK Standard Spark Plug Box of 4 (LFR6D)

When it's time to replace the spark plugs on your 2004-2010 Volvo S40, you want a part that's going to get the job done reliably. These NGK Standard spark plugs are a popular choice because they're built to the same specifications as the original equipment your car came with. They use a pure copper core for excellent heat transfer, which helps keep the plug at the right temperature for consistent performance. Plus, the trivalent metal plating on the shell makes them easier to install and remove, even after they've been in service for a while, by resisting corrosion and seizing.

NGK has been making spark plugs for a long time, and their standard line uses a high-grade alumina silicate ceramic insulator. This material is strong and helps dissipate heat effectively, contributing to the plug's overall durability and performance. The triple gasket sealing is also a notable feature, designed to prevent any combustion gases from leaking out, ensuring your engine runs efficiently. These plugs are built for a long service life, so you can expect them to keep your engine running smoothly for many miles.
