1. AMS and CSF are very similar
2. For cooling, CP bung is more than enough.. For safe power direct is better but still no released options (CSF just announced manifold with meth bungs)
3. Small size tanks engine, bigger in trunk. I tried both and prefer trunk for added capacity and safety
Yes I did that with my Akrapovic exhaust.. Since the package was too big to be delivered. A few papers here & there with some charges and it was released. This is in Kuwait btw, I expect something similar in the US
Lift the car to install, with the wheels hanging springs will be uncompressed and you can stick them on
Yes I added around 5 iirc to each spring in the rear
