I have the M1 and the D+ in my stash. There are two of each kind. I got them on sale for cheap on a pair of Pep Boys coupons. I must have paid no more than $7.00 for all four together.
I think the Fram Ultra, the best ones from NAPA, Bosch D+ and M1 are all in about the same league. The old Fram Extended Guard was almost as good as these, but is being phased out in favor or the Ultra.
Not quite. Read up on the filter testing posted here recently. The m1 filter was average,the Bosch was a bit better.
