Ok,
So I decided to start to get parts sorted for the single turbo conversion on my GTB BG5, looking at upgrading to a podfilter. Now there are rumours about the K&N (RR-3001) that because it's oiled it ruins the AFM, I quesioned this to K&N supplier and was told that it only ruins the AFM as people don't oil them properly and tend to over oil them.
So looking at the RR-3001 as a possibility, what else should I look at performance wise, APEXI vs K&N, vs a HKS? I've also been told that the K&N RR-3001 has a 3" neck and there is little room in a Subaru without relocating the AFM.
Basically i'm just looking for something with decent performance gains and 'bolt on' with adaptor. Without going to the hassle of relocating the whole AFM etc. This is going in a BG5 Legacy.
Any help would be great, i've read through the previous forms but doesn't really give me any evidence to suggest the reasons or even personal experience given the information above.
THanks,
