Excellent Plugs. Excellent price.
These are excellent plugs which normally come standard in newer Toyota cars. I installed these in my 2009 Camry 4 cylinder and also my 2004 Sienna XLE V6. The rear 3 plugs on the Sienna are next to impossible to get changed. What a plus that these plugs don’t have to be changed until 100,000 miles again. My originals of these plugs had 90,000 miles on them and I’m sure they still had at least another 25,000 miles left in them at minimum. They were in great condition after 90,000.

They're spark plugs...
Verified Buyer -
What can I say here? They're spark plugs, replacements for the OEM Iridium plugs in our 4Runner. Unscrew the old ones, screw in the new ones, just be mindful of what you're doing as with any spark plug replacement. They did the job.
Bottom Line Yes, I would recommend to a friend
OEM Correct
Verified Buyer -
These plugs are the original plug used by Toyota when new. Originals lasted 90,000 + miles. Replaced with Bosch which lasted only 40,000 miles before the Iridium tip disappeared. Hope to get 90,000 out of these.
Bottom Line Yes, I would recommend to a friend

Great spark plug.
Verified Buyer -
Installed these plugs in a 2002 Toyota Camry with a 4 cylinder engine. Previous spark plugs were the same kind from the factory, and they had almost 100,000 miles on them with no drivability issues. Plugs were still in great condition although there was a small amount of oxidation on the electrode. Since installing the new plugs, fuel economy has increased by 3mpg(about 10%).
Bottom Line Yes, I would recommend to a friend
