Spark plug Autolite or Denso

Denso 3289 is what I run.

398k on the clock, like 50k on these plugs, she runs clean and smooth.

Denso for my runner

Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that

Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.

OEM are actually cheaper than a lot of aftermarket plugs. Buy from a place like bell Lexus or just get the denso branded equivalent. They last hundreds of thousands of miles in some cases, so OE has certainly proved its worth

So i just ordered a pack of 4s (the left one is from Denso Japan) from a local distributor carrying Denso spark plugs and of the 4, 3 are made in China and 1 is made in Japan. Comparing them side by side, the China ones definitely look subpar to the naked eye.

If you need new spark plugs... Don't use Autolite.

Autolite plugs are junk. You’re better off leaving those 200k OEM plugs in it.

Throw those autolite plugs in the garbage where they belong

Yea,get some ngk’s or denso,autolite plugs are garbage.
