NGK Standard Spark Plug (BCP6ET)

When it's time to replace the spark plugs on your 1991 Peugeot 405, 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 meet the original equipment specifications for your car. They use a pure copper core, which is great for pulling heat away from the combustion chamber, helping to keep things running smoothly and preventing the plug from getting too hot.

NGK uses a high-grade alumina silicate ceramic for the insulator, which is strong and helps with heat transfer. The metal plating on the outside isn't just for looks; it's a trivalent plating that helps prevent corrosion and makes them easier to get out next time you need to change them, without them seizing up. Plus, they've got triple seals to make sure no combustion gases sneak past the plug.

This is a box of four plugs, which is exactly what you need for your 405. They're a solid option for keeping your engine running right.
