Air Filters

[KevinPhillips]

Wanting to install Cold air intake, does anyone have opinions on AFE versus AEM? Is the price difference worth it?

KevinPhillips,



Yes the AFE Pro Guard 7 flows the air but stops the dirt, check this out, it applies to any 4 layer gauze filter etc:

FLOW RESTRICTION FROM BEST TO WORST:

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

Mystery Bargain 2. 4g

Amsoil 2. 7g

WIX/Napa 4. 4g

Purolator 5. 0g

K&N 6. 0g

UNI 7. 9g

Note: The Purolator was reported to have a seal malfunction during the test and passed more dirt than it would have with a good seal.

Interesting. SPICER





As you can see the PG7 did very well, call us if you have any questions or need a system.
