Review on Taylor Cable 70051 Black Spark by Marc Tufa

Based on our own experience we regret purchasing this product for our automotive needs. While the installation was simple and straightforward, we did not notice any improvement in engine performance or fuel efficiency as promised. The price point was also quite steep for such lackluster results. The only pro is perhaps the sleek appearance, but that is not enough to justify the purchase... Overall, we would not recommend this product..
