The video compares the performance of different spark plugs, including NGK, Auto Lite, III, and Polestar, in terms of fuel efficiency and horsepower. The host conducts several tests, including a no-load test and a load test, using a see-through engine and a high-speed camera to observe the combustion process. The results show that the III and Polestar spark plugs outperform the NGK and Auto Lite spark plugs in terms of fuel efficiency, with the Polestar spark plug providing the best results. The host also tests the NGK Iridium spark plug, which performs well but not as well as the III and Polestar. The video concludes with a racing competition between a go-kart equipped with the Polestar spark plug and a "Farmer Bego," with the go-kart achieving a new top speed but still losing to the Farmer Bego.
1. The test was conducted to determine if different spark plugs affect fuel efficiency and horsepower.
2. A see-through engine was used to observe the combustion process and flame pattern of each spark plug.
3. The test engine was run at 3,000 rpm using an electric motor.
4. Four different spark plugs were tested: NGK, Auto Lite, III, and Polestar.
5. The NGK spark plug was used as the baseline for comparison.
6. The Auto Lite spark plug was tested second and showed a slightly more immediate combustion than the NGK.
7. The III spark plug was tested third and showed a slightly more consistent symmetrical flame curl pattern than the Auto Lite.
8. The Polestar spark plug was tested last and showed a very immediate and intense combustion.
9. The fuel efficiency of each spark plug was tested by measuring how long the engine ran without any load applied.
10. The results showed that the Polestar and III spark plugs lasted a little over 46 minutes, while the NGK and Auto Lite spark plugs lasted around 45 minutes.
11. The test was repeated with the engine under load, and the results showed that the Polestar outlasted the III by around 10-12 seconds.
12. The NGK Iridium spark plug was tested and lasted around 46 minutes without load and 36 minutes and 31 seconds under load.
13. The III and Polestar spark plugs offered a slight fuel advantage over the regular NGK spark plug.
14. A go-kart was used to test the performance of the Polestar spark plug, and it achieved a top speed of 31.2 miles per hour in 27 seconds.
15. The farmer Bengal completed the race in 21 seconds at 49 miles per hour, beating the go-kart.
