NGK Glow Plugs Box of 1 (Y-732J)

When you're getting ready to work on your diesel Jetta, you'll want to make sure you have the right parts to get it starting reliably, especially when it's cold out. This product is a single NGK glow plug, part number 5909, also known by its model Y-732J. It's designed to replace the original glow plugs in your 1997-2004 Volkswagen Jetta, and is also compatible with certain years of the Beetle, Golf, and Passat.

NGK builds these metal glow plugs with a heating coil nestled in heat-resistant magnesium oxide. This material is a great conductor of heat, which helps the plug warm up quickly, and it also protects the delicate heating coils from the vibrations and shocks that come with engine operation. The gas-tight sealing helps keep combustion gases out, preventing carbon buildup that can cause short circuits. The metal composition and unique shell design work together to transfer heat efficiently, ensuring your diesel engine fires up smoothly.
