Denso (3426) FK20HR-11 Iridium Long Life Spark Plug, Pack of 1

My 6 where shipped in a huge box let me tell you. Most if them slipped out of their individual boxes, some people might like that but not me. They might work maybe possibly, check them they look great. Checked their gap gently like a baby, all gapped correctly. No issues, made my engine great again, no wall needed.

These are the correct OE plugs for Toyota/Lexus. My wifes Highlander had the original plugs at 180,000 miles.Still ran ok but were really worn.It took me over 3 hours to install.the wiper cowl assy had to come out to remove the intake plenum to gain access to the rear 3 plugs. the front plugs took 10 minutes. runs good now. I just did the same job on my Lincoln only took 1 1/2 hours. I highly recommend using only the OE brand spark plugs on any late model engine.

I use them for my 2011 toyota sienna since those are the OEM. And they work fantastic car doesn't feel slow any more. Or like if there was a barely misfire. It just feel smooth 😌. I recommend you doing them.

Finally decided to install new spark plugs in my 2011 Toyota sienna van with 198,000 miles! Had no problems with original plugs just decided it was time to change them since I intended on keeping it another 100,000 miles. See the photo of the original plugs versus the new one on the far right! Hoping to see a little boost on mileage.

Still testing the performance in my van, at high speeds seems to be some stalling not sure if there has to be more work done, only installed 3 of the 6 plugs, I threw away the originals big mistake can't compare performance, not sure why it's recommended to change plugs at certain mileage if everything is working fine well live and learn, still working on the vehicle to verify authenticity.

Bought these to replace the plugs in my 2015 Lexus RX350. They are the same exact part number from Denso as the OEM.I will say the pricing isn't the greatest on Amazon when I bought them at $13/each, but it's convenient and I didn't have to go to the Toyota/Lexus dealer.These are indeed 100% legit, I scoped them out with a magnifying glass, they are exactly the same as what came in the car from the factory.Lexus RX350 Toyota 3.5L

This poor rating is for Amazon packaging, not the Denso spark plugs. Plugs seem to be OK despite the poor packaging by Amazon. The six plugs were just placed loose in a padded envelope and were obviously tossed around with other packages in that half of them were out of their boxes, and the other boxes had been crushed. The porcelain sections of plugs can be fragile, hopefully these will be OK. With all of the products you ship, you should know better than this.........

These spark plugs replaced the original Denso's that there factory installed. I got 130,000 miles from the original set of Denso's. The car was running really good even with the high mileage on the originals. So what does that tell you about Denso Quality? Also, remember not to use Anti Seize, they don't need it, and it will adversely affect your torque tightening.
