What is the diameter of the AEM
pipe? I think it should be 2 3/4", but correct me if I am wrong. I can get some pretty good prices on K&N Filters, but it depends on the size needed.
For 2 3/4" I have the following. Price includes ground shipping: K&N
Round Tapered Filter w/ Rubber End Cap - $30-37 (MSRP $40-50)
Round Tapered Filter w/ Chrome End Cap - $40-48 (MSRP $55-67)
Round Tapered Filter w/ Metal End Cap - $47 (MSRP $66)
Anodized Round Tapered Filter w/ Inverted Cone Filter Top - $55 (MSRP $80)
X Stream Round Tapered Filter - $60 (MSRP $85)
If this is not the right diameter for your application, please let me know what you need and I will get you pricing. Also note MSRP's above do not include shipping.
