I'm going to do stage 1 & 2 but have I got this right ?

Stage 1 (the high flow replacement for the original like K&N for example)

Stage 2 (the ring that goes in the top to replace the snorkel)

Now assuming I have that right I am confused:

Why would I put in a high flow air filter and then restrict the flow of air going in by putting in the ring that has what appear to be a smaller aperture?

I'm obviously missing something so can someone explain.

Is the stage 2 ring just there to replace the snorkel and hold the filter down ? Can I just cut my snorkel off completely and use that instead of the stage 2.

Stage 3 is the open sided to the airbox right ? don't really want that as I want the highest possible wading depth.

Thanks all in advance.

p.s. I am all kev modded out and have a single MTC so these filters are the last part of my intended mods to the engine, can't wait...
