quality, engine and perfect fit

Though many of the sellers want to sell this model spark plug with difference # codes. I received from this company exactly the spark plug model that Toyota says should be the only one used in my 2017 Camry SE 4 cylinder. They are performing perfectly.

good quality spark plugs.

Awesome OEM NOT FAKE Highly recommended great price.

Awesome!!!!!

Not much to say, they are great spark plugs.

Update: They lasted less than 20,000 miles.The electrodes were completely consumed and the gaps were far too large and this is on a perfectly healthy engine. Turns out, I received a set of counterfeit plugs.I ordered 4 new ones from a Rock themed auto website and when comparing the font printed on both sets of plugs and doing a little research, I can confirm that YES they do make knock off spark plugs and you better believe you can get them from Amazon.Check your gap, people. For my Rav4, these are the perfect plugs, however the gap spec. per Toyota is .043” and these “pre-gapped” plugs came with a different gap on every plug varying from .023” up to .035”. “Pre-gapped” is a farce of the industry, you CAN get away with installing these without checking the gap at all and they may do just fine. Some engines are pickier than others, but manufacturers don’t want their iridium tipped electrodes getting damaged before install so they all say “do not adjust gap” but the fact is, all these plug part numbers fit multiple engines from various manufacturers and they all require a different gap, so how can one plug fit all those differently spec’d engines? Smell what I’m steppin’ in?Anyway, enough of my rant. Just Google how to carefully check the gap on Iridium plugs without damaging them and you’ll be fine. Our original plugs went 106,000 miles with no issues and getting 23 avg MPG at worst, so these are the plugs you want. They last so long why buy anything else? Let the engine cool completely before removing. Unsure if these fit? Check your owner’s manual. Most cars have the OEM plugs listed.
