    Your owners manual will tell you the exact replacement. Suggest NGK or Denso Irridium

    If you have been issue free, why not just do a direct replacement of what you have?

    Denso and NGK are both superior spark plug manufacturers.

    For my 22RE, the NGK seemed to work better, but those were the traditional low tech spark plugs. The truck came equipped with NGK.

    From what I read in Tundra forums, Gen2/Gen3 owners say the Denso Iridium plugs perform slightly better than the NGK equivalents. Use the spark plug number recommended in your Owner Manual (Denso SK20HR11). You'll probably never know a difference with either brand.

    2014 Tundra CrewMax 4wd in Magnetic Grey Metallic w/ 4" Rough Country lift on 35x12.50R17 Yoko Geolander M/T G003 wrapped around Bronze Method 17x8.5 305NVs, exhaust is single Carvrn-R 5"dia. x10" Dumped right after axle on existing original post muffler pipe(Yup. It's pretty Freakin LOUD when I get on the gas peddle!! Lmaoo).
    Hey All! I just hit 120k miles on my 2014 5.7l 4x4 SR5 CrewMax. I bought it used with a little under 100k. My gas mileage has recently dropped significantly(I can be an Absolute Lead Foot, so my mileage was never too good, but not INSANELY BAD, in part due to the lift and 35x12.5's also, but I'm now see REDICULOUS MPG's!), that would be from about 13-14 avg mpg down to about 10-12 avg mpg.. I have ZERO IDEA what maintenance was/wasn't completed by previous owner. So I'm guessing plugs might be the way to go.. So I was looking at plugs and one of the recommended plugs, were the new NGK RUTHENIUM HX plugs... They sound awesome to me, but has anyone tried them by any chance? Is it an upgrade or more snake oil? Please let me know! Thank you in advance for any advice anyone might be able to provide!!

    I went with the denso sk20hr11

    I noticed my truck couldn’t go pass 90mph and I was like what the heck is going on so I replaced the spark plugs and my truck felt much better because the plugs were bad.
