It's good, but it needed some processing.
When I installed it, the Throttle would not open fully.
I had to cut off the Pulley part to make it fully open.
I ran it after I modified it and it was very easy to ride.
The jerky feeling at the beginning of opening is completely gone, and the second half of opening feels quicker.
If no processing is required, I would definitely recommend this product.
I'm sure it's a little different for each car model, but for your information.
