Ignition Coil Spark Plug Question

[sealuva]

I have a 2006 Lexus LX470. I see Denso showing only one part number on their site for ignition coils: 673-1303, however I see Toyota website showing two different part numbers for the coils depending on the year I'm guessing. Is it safer to find the coil packs that pertain to the Toyota part number specific of: 90919-02259?
The part number I regularly see for Denso say: 673-1303 but with the Toyota part number of: 90919-02230
Should I stay with the one that states the part number of: 90919-02259?
Just a bit confusing.

Also I am asking if the following Denso spark plug will work:

Denso (3297) SK20R11 Spark​

I just replaced all the ignition coils and spark plugs with the same part # Denso coils and plugs.

In researching Mud, the price differential wasn't worth it to go all Toyota.

I just pulled a set of sk20r11 plugs out of mine in the baselining process. They worked and looked fine. It’s a great option to go with.

Denso plugs will be great. Don’t get the auto zone specials.

Toyota Denso or Denso, either are great. NGK are also good IFR6T11 (Old#: IFR6A11). The biggest concern, are they legit. Many bootlegs coming out of China, which are total junk. I found the Denso TT to be a good plug, wherein China can't bootleg the 0.4mm Twin Tip electrode.

A good Denso, will not need gapping. The SK20R11 will be factory set at 1.1mm, the IK20TT at 1.0mm. They should be within -+0.05mm of spec. Denso recommend, we not change gap. As it may damage the electrode. But if you know what you're doing, it can be done. But it should not be needed. If you find gap out of spec, return it!

It's best to buy from Toyota Dealership or Denso Distributor. Ebay, Amazon, Parts Store, etc., are laced with Bootlegs.​

Genuine or Bootleg parts

I buy a lot of parts from on-line sellers these days, mostly form parts houses or Dealerships. Now and then I'll but from say ebay or Amazon. Seems I get Bootleg from China more often from ebay sellers. I've had some of those low priced Denso coils that look so good. But with close inspection...
