Filter Test

 

Not sure how a BMW filter compares to an AC Delco, but that is interesting. Jim Conforti is a known and respected tuner of BMW's if you didn't know, he know's his stuff.

Here was my little test a long time ago between a K&N and a regular paper Fram.

 

K&N = 316 rwhp

Paper Fram = 318 rwhp

 

The only difference between the two pulls on the dyno was the 30 seconds it took to switch them out.

 

To me the difference is negligable.  The only advantage a performance filter has is that it is cleanable and reusable.

I wonder how the Amsoil foam air filter would compare in the test. It would be interesting to see due to the physical make up of the filter being foam over pleaded paper or cotton gauze.

 

I have read a few oil analisys reports using the foam and they showed excellent protection. The silicon count was way down.

 

It would be interesting to see. :flag:

    • New to this forum.  Also looking to tune a 6L80 and trying to work out all the issues in my transmission swap.  I have a 6.2 diesel (1983) and have removed the TH-400 and about to put in a 6L80 with a TCM-2600 interface and don't have a clue what I doing after that.  Did you (Leatherneck/RAV3) get your slip resolved? I too hate to spend that kind of money on a tuner that hopefully I will not need too many times although from what steelerdude15 added about the HP Tuner being great for diagnostics would be a plus.  I am also from WNC but below you in Columbus.  Any helo would be greatly appreciated.

    • Wouldn't swapping out the original AFM/DFM parts for a complete Delete Kit be the best route to go if one could afford to go that route?
    • It comes with directions but yes, generally, it's the same.  Also, get you the dipstick stuff to install dipstick so you have one.
