What are the advantages and disadvantages of using the cone type filter you find at auto parts and ebay compared to the afm thats on it factory. is it worth the money and what all is involved with changing it to the cone filters

 

The AFM is required for your EFI.

 

had a k&n fipk for my 22re and it just had a plate that bolted to the afm

 

ahh.. got it..
Advantage: potentially more air flow = hp
disadvantage: K&Ns have been shown to let in more dirt as well as more air.

 

So basically all that stuff on ebay is hogwash, it cant be installed on my efi system?

 

I don't know what's on ebay, but you need to keep your AFM - not the box itself, but the sensor that's setup in there. IF you can fit a cone in there, it's entirely possible.
