I'm kind of shocked that Toyota put that thing in there. It's very restrictive. If my car saw tons of off-road and dust, I'd probably leave it and just do the K&N. But it doesn't, so I think it's well worth it.

I drive the Black Rock playa and at times up to 5th in line. I will definitely remove the HCF. If my regular filter plugs up, I can remove it, shake it out or just replace it. If the HCF plugs up, well, that sucks.
I appreciate the discussion.
