I switched from the blue "oil impregnated" style filter. Apparently, and it makes sense, the residue from the "oil impregnated" filters can mess up the MAF sensor. I think there is a higher possibility after you clean the filter. Anyway, the gray filter is a dry filter. If they hold up even half as long and are as efficient then I will be happy.
