MONTIAMO LA CANDELA PIU' COSTOSA - FA DAVVERO LA DIFFERENZA? NGK Iridium su Vespa 50 special 160cc

Testing the difference in feel between a standard €5 spark plug and an iridium one. Is it worth it? Final thoughts at the end of the video.

On very sensitive engines like my 160cc, I have to say I noticed the difference, mainly in engine smoothness and combustion speed. It's not a huge difference, but in the end, it's worth spending a little more for a key part of the engine.
