Review on Denso 671 4279 Coil Plug Boots by Bryan Moon

Using this product our team found that the manufacturing quality of these ignition parts was quite poor. While they are affordable, we received a large quantity of defective ones that led to frustrating delays in our automotive repairs .The only benefit we found was the low price, but the cons far outweighed that. The lack of reliability from these ignition parts made them an obvious choice for us to stop using altogether..
