Ok so I have an Injen, but I *think* (and hope) that the filters for the injen, AEM and fujitsu for our vehicles are interchangeable (all 3.5" diameter outlets with 5" length??? will 9" fit btw?)

With that assumption, I'm looking to replace my injen filter. The question is what is the best filter out there?

I've heard good things about the AEM dryflow filter, The Fujitsu design is very impressive and looks like the best filter imo, K&N typically makes awesome filters but I dont know much about their cai filter.

What have people used and recommend. Any recommendations? Please post model numbers, size of filter, and links on good places to buy these.

Here's a link to the aem filters (dont think the 9" fits tho):

I've decided to go with the Fujita filter - best price I've found was here:
