Weather was nice this weekend so just for fun, I opened up the hoods of my cars and looked at the labels for different parts seeing what companies made them. The I35 has many Hitachi and Mitsubishi electrical parts like ignition coils, alternator, starter, etc. My Accord didn't have any from what I could tell but I saw a Denso radiator, alternator, MAP sensor and a starter by Mitsuba. The spark plug wires were made by Sumitomo (yeah, the tire company). My 2013 Pilot had some Hitachi parts but again, a lot of Denso stuff. I know Honda & Toyota heavily use Denso but I was surprised Nissan didn't use them at all for our cars.

Wish Nissan would've not gone with the problematic Calsonic Kansei radiators, though

Where was your Honda assembled?

There's a clue

All plastic radiators fail. Only a fool would trust one even if it were made by an ancient Samurai

The reason Toyota and Honda use Denso where Nissan uses Hitachi has to do with Japanese Keiretsu and the core banks associated with each major company.

Some years ago you would see Autolite in Ford, Chrysler, Studebaker, Packard and ****** vehicles but never in a GM product. Likewise GM and affiliates would use Delco AC - but you would never see those products in a Ford or Chrysler.
