Review on L78V SPARK PLUG Pack 4 by Evan Casillas

Using this product our team found that it caused a significant decrease in the overall performance of our Automotive vehicle .The spark plugs continuously failed and caused misfires, leading to a frustrating driving EXPERIENCE and costly repairs. The only positive aspect is that the product was easy to install. However, the negative impact outweighed any benefit. We strongly advise against using this product for Ignition Parts or any other Replacement Parts..
