the cover comes off easily you lift it up in the front then just pull towards you, there are two clips that fit into the slots at the rear (top) of the picture.
The only variation I found is inside the new air box. The round hole in the bottom of the box DOES NOT match up to the existing hole in the car so you need to cut away some metal for it to fit in place properly.
The vac line needs to be plugged into the Volant port or you may throw a CEL.
As you can see the stock assembly is quite cumbersome as it is not designed for efficiency but rather it is designed to silence (read interfere with) the air intake to the engine.
the last two are the system installed.
You do need to find the sweet spot for acceleration as it changed for me. before it was about 3/4 throttle for hard accel, but now its about half throttle to get both the elec motors in play and the gas engine. if you floor it from a stop light you can hit the rev limiter. I think to optimize the system you would need to re-map the onboard computer but I prefer warranty to racing!
