My wife's Matrix will be due for an air filter soon. I wasn't impressed by the aftermarket filters I looked at, so I stopped by the dealer to pick up a gen-yoo-wine Toyota filter. It's a Denso product. Guess what's stamped on the filter element? Made in USA. I wasn't expecting that. The aftermarket filters I looked at were made in China or Israel. The Toyota air filter costs more than a Purolator or Fram, but it seems like a better filter, and its having been made in the U.S. makes me feel better about paying a few more bucks.
