What made you choose this particular product?
It is a well made product, power remains smooth but definitely makes the car feel more alive, whith way more torque around the 4,500 rpm range.
Is this your first time buying from this brand? Did you consider other brands?
Yes, this is my first time buying from this brand. I did consider the jb4, but this was a more reliable option.
