Spark plug NGK or Denso

NGK or bust.

Most manufacturers don't make their own spark plugs anyway. They are usually just rebranded Denso/NGK/Bosch. I would have no concern fitting NGK spark plugs provided the part number is correct.

Use NGK brand and replace it.

There is a meteor 350 in my riding group with an iridium plug which i will say he Acquired Unexpectedly, and damn the results are just awesome.

Denso 3457 (FXE24HR11)

Why? It's the plug recommended in the owner's manual and I have never seen anyone have issues with this plug.

Why are they noticeably better than other equivalent plugs from reputable brands, I honestly don't know as it seems that the differences should be negligible. Plugs are one of the areas where the car is very fussy.

Mine had NGK, so that is what I put back in.

I finally changed out the OG Denso spark plugs on my wife's '10 RX350 at a shameful 415,000 kms. Wasn't idling rough but some low-rpms hesitation. Plugs still basically worked fine, though.

NGK are my goto plugs but I’m pretty sure you’ve got the plugs that are notorious for breaking apart when removing them

The only things it’s done to me is die (dead battery) and a misfire that cause it to go into limp mode at 118k miles (I went cheap on spark plugs instead of doing NGK’s)

I’ve had several Denso plugs do this on a couple Camrys I service, and our own. All 2.4 cars. Caused tow ins for both husband and wife’s cars. I’ve fired denso as a spark plug provider, too many failures.
