Buying advice

Choose a glow plug based on your engine's compression and climate. Hotter plugs (e.g., OS No.8 or Tornado T5) are better for cold weather or low compression, while colder plugs (e.g., OS No.3) suit high compression or hot climates. For general sport use, a medium plug like Traxxas 3233 or Dynamite NP01 offers good value. Always match the plug thread to your engine (most are standard 1/4-32). Buying multi-packs saves money, but discard plugs that show wear (discolored coil) to prevent engine damage.
