I just recently installed a similar one on my Kia under the premise that if it don't help, it won't hurt. I used a coarse bronze/brass? scrubber called Choir Boy instead of steel wool. Only been in for two weeks so too early to tell if it helps, however several guys on the Kia Soul forum have put them on and shown the gunk collected over a period of time.
