    • High quality Denso
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.

    • OE style
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. ... show more

Review Image by KP KP
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. ... show more

    • Are they fake or not
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. ... show more

This is the 2nd set I purchased because the first 3 out of 6 failed. I'm not sure what happened but the tips worn out faster than other so I'm not sure because of my car which is a 2010 Lexus rx350 which ran fine after and before these spark plugs failed. failed spark plugs causes all kind of headache and time and money before I've realized it the fouled spark plugs. first it gave me random misfire for all kind of cylinder and it would jumps all over the places, and I've tried all the tricks and swaps then finally took to the mechanic. Even the mechanic did compression test and didn't know what's going on. I'm not even sure why he didn't diagnose the spark plugs at first even though he's been a mechanic over 30 years. I think this called "ghost misfire" the causes the car was running horrible in cripple limped mode, it was shaking and the RPM was bouncing and idle way too low. so the bottom line is don't think this is the best of the best and think you're set for a long time ... show more
