They are all the same, doubt you will find any real data anywhere that says AFE filters (not sure exactly which filter it uses) is superior to K&N filters. Besides, changing the filter out is the easy bit, you can put in any filter that fits. The GruppeM intake looks fantastic. AFE is not consistent with the philosophy!
