I've had my Cobra for 8 years now. During that entire time I have used the Mobil1 M-301 filter. Last week I changed to a Moroso racing filter. The micron rating on the Moroso is 27 microns, the micron rating on the Mobil1 is about 10 or 11 microns. I'm getting just a little more pressure (3-5 PSI) both at idle and at running speeds. I thought there would be a bigger difference. I'll probably leave the Moroso on for the winter and go back to the Mobil1 filter in the spring.

I also changed from Mobil1 5W-30 to Redline 5W-30 at the same time so the comparison is somewhat shakey. The published data shows the Mobil1 5W-30 to be just slightly thicker however.
