Quick question guys about an intake

Had the R2C at first and loved it best looking if looking in engine bay, but I now have Takeda Long Tube and love it even more not quite as good looking in engine bay but that look through grill is mean. Performance wise and better for your vehicle I would go with the Takeda just cause not pulling air straight from engine bay like the R2C would be doing.

I've been contemplating which intake I will end up going with, the cliffs notes version of the big 3 CAI's look like this:
Takeda- probably one of the most popular, design puts the filter in front of the grill, rain guard is an added recommended expense but not necessarily required. Some question the single filter design and spend extra on dual filters (K&N, AFE, etc.) and cite some improvement both in sound and from the "butt dyno". (This is prob. what I will do eventually)
Injen- Good company that makes quality intakes. Design puts the filters lower leading some to be concerned that it may suck water more easily. You can add filter guards or air bypass as added expense. Injen offers polished or black colors.
Stillen- Well known in the Nissan/Infiniti community, requires some light modification to fit properly, dual filters placed behind the grill.
At the end of the day the reality is we're not gaining much hp at all from adding a intake as the VQ motor is designed well, nearly to its potential, and short of forced induction you won't add much. So it seems most would say that an intake is an expensive way to look nice or sound cool rather than as a significant performance boost.

R2C and Takeda both claim approximately the same HP gains...(all intakes claim unrealistic gains no matter what car you own) so does anyone have factual before and after dyno comparisons? All variables held constant? I am guessing unless you track the car and heat the heck out of the engine bay they are probably equivalent in power production...which is minimal in either case.

Do a search here,
There is a thread with dyno tests of a R2C vs a SG3.
It's a good read and includes metrics on performance, and actual measurements of cold air intake.
Long story short, the R2C had very similar HP gains, and at a lower RPM...in a band more likely used on the street.
At least that's what the author posted.
IMO with the filter box mated against the hood and radiator baffle, the air largely comes from the same intake vent through the baffle.
Unless someone can show the CFM largely exceeds what the OEM intake port can deliver I see no reason to expect heat soak to be a concern.
For that, it would have to draw air fast enough to overwhelm the normal intake and create enough suction to defeat the hood and baffle seal.
Looking at the intake and dyno numbers I say probably not.
So I won't bother with a G3 to avoid cutting my radiator baffle, and so I don't have to remove the Front compartment cover to change filters.
No big deal either way, just a preference for me.

Throw away or Washable Filters
I take it that all of the kits have a (K&N style)washable filter or is there any with a regular disposable filter? Not a fan of cleaning and lubing filters and would just rather chuck it and replace.
