K&N vs. AFE PRO GUARD 7

[actiondcpd]

I've got a 2002 EX with a banks stinger plus system. I bought this truck used and even though it had the banks kit installed, it still used the factory air box with upgraded filter. I'm looking to add one of these intakes. I've noticed a bunch of people prefer the AFE over the K&N. It is almost twice the price so my question is it worth it? What makes the AFE one so much better?

My biggest reason for obtaining the AFE was the proguard7 filter does not open up and let dirt through like cotton filters such as K&Ns. When it came to getting cold air to the intake I also couldn't find a better source than the Stage II. It is pricy though. I purchased my from dieselmanor.com. They have it on sale right now by the way. Cheapest I've found it so far...

actiondcpd,

Here's a ASE test done on soem filters, this is the reason we sell the AFE PG&:


The following is the complete test results. In order of rank from BEST performance to WORST in the categories of FILTERING EFFICIENCY, FLOW RESTRICTION, DIRT HOLDING CAPACITY and TOTAL DIRT PASSING THE FILTER DURING TEST.

AC Delco OE 99.93%
Baldwin 99.72%
No name filter (made for gas engine, 1/3 less pleats) 99.32%
AFE ProGuard 7 (73-10062), panel filter 99.23%
WIX/Napa 99.03%
Purolator 98.73%
Amsoil, new style 98.63%
UNI 97.93%
K&N 96.80%



FLOW RESTRICTION FROM BEST TO WORST:
FILTER RESTRICTION in Inches H2O
K&N 4.54
Mystery bargain filter 4.78
AFE Pro Guard 7 Panel 4.99
Purolator 5.05
WIX/Napa 5.06
UNI 5.40
Baldwin 5.71
Amsoil 5.88
AC Delco 6.23
TOTAL DIRT PASSING THE FILTER DURING THE TEST. This is how much dirt your engine will take in if you use the filter for the duration that would cause the filter to become "dirty" enough to need replacement or cleaning. The "Dirt Passing The Filter" is the dirt collected by the "Post Filter" during the test.
FILTER DIRT IN GRAMS PASSED
AC Delco 0.4 g
Baldwin 1.1g
AFE Pro Guard 7 1.8g
