Exactly as said. The filters can be cross referenced. This is because the filters, filter better and flows better. Some of this idea type will be explained shortly on my Evo vs Twin Cam motors for HDs, below.

True because of higher PSI the filter goes to by-pass. This is not an issue on the SS filters cause they flow better and more consistantly.

I'm going to post up a thread I worked on back in June for another forum...

About EVO vs Twin Cam oil filters.

I always knew there was a difference as decribed but it bugged me when HD came out with their new oil filter that works on both motors. So I started into my homework.

topic that came up on another forum... the appropriate oil filter for the correct application. For BDB, some big dog owners have twin cam harleys, and we have had the K&N 170 vs 171 debate. I also include the notorious K&P in my research that I will start to post now...
It's going to get long... hopefully worth your time...
