Callaway
I'm looking at their stage 1 (air intake and exhaust).
I'm a daily driver...would i need to worry about driving in the rain or small puddles with that intake? I believe it's a cold air, bottom feeder type intake.
I live in Oakland, CA.
Air intake alone is $490
Exhaust alone is $1095

> 1. What brand of filter do you use?
We use a panel filter manufactured for Callaway by Green Filter. This
design uses two layers of cotton fabric filter media instead of
multiple layers of gauze as used in other brands. The fabric is thinner
and stronger than gauze to allow high flow rate while maintaining
superior filtration characteristics. The perimeter molding process
reduces the amount of rubber that migrates into the filter media,
effectively increasing filter area. As with other cotton-based filters,
the Callaway filters are washable and reusable.

The Honker C5 works fine for larger engines. In fact, the main reason
for the development of the C5 Honker was the loss in power that we
experienced with our 550 bhp 6.8 and 7.0L engines when we took them
from the engine dyno to the chassis. We determined that the airflow
restriction in the best systems that were available at the time would
sap as much as 20 hp.
Using the Honker C5 with our billet throttle body and LS6 MAFS, we
recorded 997 cfm. With the OEM throttle body and LS1 MAFS, we measured
846 cfm. Testing was performed on a SuperFlow 600 bench at 28" H2O.

A significant air flow quantity and quality advantage. The objective
was to maximize the inlet duct's cross-sectional area over the
radiator, forming a smooth path from filter element to throttle body.
This gave us more air with less turbulence. In order to do this, we had
to relocate the MAF.

Condition #1: Engine idling, car is not moving, coolant fans are off.
The air in front of the radiator is cooler than underhood air, but it
can be warmer than ambient air outside of the car. This area is not
stagnant because of the motion of the inlet air drawn into the filter
element.
Condition #2: Engine idling, car is not moving, coolant fans are
running.
In this case, both the coolant fans and inlet air are drawing cooler
air into the area in front of the radiator.
Condition #3: Engine at cruise RPM (or higher), car in motion, coolant
fans on or off.
Here, even more outside air moves into the area in front of the
radiator, providing cooler inlet air temperature. We've also measured
slightly higher than ambient air pressure in this area. GM did a good
job designing the body to direct outside air into this area for cooling
purposes when the car is moving.
I like it when a company is willing to spend this much time and testing to explain their product. If we could get this kind of stuff from all of the manufacturers then maybe we could make a sticky or something so the "what air intake" question is answered. Is it worth the money, I don't know??
