I have installed all 3 pivot products (raizin, spark and ignition earth).
I have posted this on another thread

My observations are as follows:
1. When i start my car, it seems to start a little quicker, but very minimal.
2. When i took off down the street, the rev goes up much much higher. I could get to 6,000revs with ease on an auto without flooring.
3. Havent really driven it for much, but the car is very quiet. I had the KN panel filter installed and that made the car a little bit quieter, but with the spark and ignition, it made it a little bit extra.
4. Car seems to drive a little smoother as you hit the speed limit.

I only have stock ICE so i cant say much for that part. In terms of light being brighter, it looks the same to me. Fuel economy is about the same. But then again, there may be a slight improvement cos 50% of the time im heavy footed. Car is dead quiet at idle. Paddle shift doesnt jerk as hard anymore when you downshift.

For me, its not a bad mod for a few hundred dollars.
