What size K&N filter (or model) no. comes with the AEM SRI? I just bought the "tubes" w/o a filter and would like to know the model number or dimensions (I can measure the inlet side, but what is the "stack height" and diameter of the filter "body?).

Any help would be appreciated! :P
 
try going to K&Ns site and putting in RX-4010, the dimensions of the injen are close to this model #, or a RX-4950, i think thats the one that comes with the K&N intakes.
 
no prob.its a 2.5 flange and 5.5 inch stack i think. I could have wrote it down wrong though.
 
Good deal. I spoke with AEM today and they gave me the following information on the filter. It is an "AEM" branded filter.

Model no. 21-203.
3" inlet flange
"Short stack" design.
I've found prices around $60 online....I say to hell with that, I'm getting an S&B :D
 
You don't need the damn model number just choose any k&n with a 3 inch opening, small or big size dosn't matter any filter shape will work to.
