Post your pod filter intake pics!

you can actually pick up an Apexi filter kit from protegegarage.com which is supposed to the be the best filter on the market. You can buy the HKS filter kit if you just want the filter and stock piping or you can stay cheap and buy an ebay CAI. Other alternatives are AEM SRI and Injen CAI. If not to go custom all you need is a small piece of pipe to use as an adapter to mount the filter and sensor in front of the MAF. You also will probably need some sort of bracket to hold the filter up so it doesn't sag.

is the apexi filter better then the k&n filter?Maz2001MP said:
and this is helpful as far as which is the best filter:

70 mm adapter or get an apexi kit to go from XXmm to 70mm.
info about the sensor(s):
The OBD-II system is programmed run self diagnostics to detect problems with the
sensors in your car. The Proteg has 2 sensors located in the intake: the Intake Air
Temperature (IAT) sensor, which (logically) measures the temperature of incoming air,
and the Mass Air Flow (MAF) sensor, which measures the amount of air entering the
engine. The IAT sensor is the small 2-wire sensor that attaches to the intake pipe
immediately behind the stock air filter. The MAF sensor is the large, box-shaped, multi-
wire sensor located between the stock air filter and the throttle body.
Most Check Engine light problems on an OBD-II Proteg are caused by the MAF
sensor. The Proteg uses a MAF sensor that is very sensitive to air turbulence. In
order to minimize turbulence, the pipes leading into and out of the MAF sensor should
be as close as possible to the diameter of the stock intake pipes, they should be as
straight as possible, and any bends should be smooth and uniform in diameter. Any
sudden kinks, enlargements, or contractions in the intake pipe can disturb the air
flowing into the MAF sensor, causing irregular sensor output and making the OBD-II
system think that the sensor is broken.
Although it is less common, installing the IAT sensor incorrectly can also cause the
Check Engine light to come on. The end of the IAT sensor must be installed some
where in the airstream leading into the MAF sensor. It does not matter exactly where it
is installed; some Proteg owners have simply shoved the entire IAT sensor into th
inside of a cone filter and routed the wires under the filter gasket, and have not
encountered any problems. However, the IAT sensor should not- be unplugged,
removed, or simply left dangling in the middle of the engine compartment. This can
cause Check Engine lights and/or decreased engine performance.

I see that vivid hass converted the CAI into a SRI. I want to do this for the winter so that my intake isn't swallowing all the water/snow. Just so I'm sure, I wont throw a CEL due to putting the filter so close to the MAF or changing the intake from it's original design?

yeah, I might have to make up a bracket. easily done though
L8R said:ive done that
jp, im just concerned about the injen not having strong support (making it an SRI) unless u make your own bracket.
actually, you can just rest it near the hole where the cai would go. it doesnt move around much at all. Ben (wetsuitxninja) has it like that. or..
ziptie!
