Review on NGK CZ104 Diesel Glow Plug by Herb Guevara

As an automotive enthusiast, I was pretty disappointed with this product. Using these glow plugs, our team found that the performance wasnt very consistent, and sometimes they wouldn't even work properly .The biggest pro to this product is the price, as it is relatively cheap compared to other similar products on the market. However the cons far outweigh the pros in this case. We ended up having to replace them more frequently than we would have liked, making them a huge waste of money in the long run. Overall, we WON'T be purchasing these again..
