What fortune 1000 company makes filters anymore? Denso I guess, yes there good. Mahle is F500, there filters are mediocre at best. M&H, First Brands, PG - not F1000?My basic rule:
Products made by a Chinese company = BAD.
Products made by a western Fortune 1000 company in one of their Chinese located plants = GOOD. The product will be the same quality as that made in their Nebraska plant. Corporate and ISO quality standards ensure that.
The manufacturer is key, rather than country of origin. Corporations are global now.
