This straight blade profile is a complete waste of money and effort. Automotive enthusiasts like me need products that will DELIVER top-notch performance, but this one doesn't meet the standard. Thanks to my knowledge gained in practice, i can confidently say that this blade is flimsy and doesn't help the engine cool down efficiently. The only redeeming quality is that it's easy to install, but that`s not enough to justify its purchase .I wouldn't recommend this product to anyone..
