Spark plugs - new or aftermarket?
My 2013 F Sport is at 82K with original plugs. Mulling over replacing them in the next year or so. Have read people pushing them until pretty late in the car's life, but I know they can be a ***** to remove if they're in thee car for too long.
I see I can get the OEM ones (part number 90919-01263) off ebay for around $80 or the non-oem Denso 4705's for around $60. Leaning toward getting the OEM's just to be safe, but I am a cheap bastard.
Any recommendations for/against changing and not changing and oem/aftermarket? Car drives perfectly as it is now.

Plugs on Ebay and Amazon are 98% fakes. Only exception on Ebay is if the seller is actually a Toyota/Lexus dealer/parts vendor. Buy local or from Rockauto.
Can look up approved vendors

The Toyota genuine and Denso plugs are exactly the same. Doesn't your car take Denso 3491?

I've even had misfire issues with Denso's from Advanced Auto. Two years after installing them, my dash lite up like a Christmas tree and multiple misfire codes. I learned the hard way but now I only buy OEM spark plugs from a reputable source (Toyota or Lexus dealer).
With my 3rd gen GS, I got 10 years and 100k miles out of the original spark plugs but decided to change them out at that point. Lexus dealer also recommended 100k mile change out.

When the time comes for you to waste your time and money replacing the perfectly fine OE spark plugs, buy the new spark plugs from a Lexus dealer. Don't be stupid and a cheap bastard and fall for the counterfeit crap from sellers on eBay advertising the proper part number that is fake junk.

You won't need to replace the OE spark plugs until you car has twice the number of miles it currently has. Those OE spark plugs won't be a ***** to remove - they'll come out with no problem, regardless of mileage. You'll see zero improvement in performance or fuel mileage if you do ever decide to replace them. Save your money for something worthwhile and meaningful...

I love your confidence and amusing curmudgeonliness as is evident on most of your posts, but I think I may decide to be better safe than sorry. I found them on ebay on sale from a dealership in Scottsdale. I think I'm gonna buy these. https://www.ebay.com/itm/234511290434.

I'd recommend you confirm the required PN prior to buying.
PN 90919-01249 is for the 2GR-FSE engine. I use these in my 3rd Gen GS (2007) and I believe they are also used in the 4th Gen GS (2013), which is also a 2GR-FSE engine.
Updated post since the 2GR-FSX is for the hybrid 3.5 L engine (I don't believe it was sold in the USA).

OK couple things. 1st off with further research I see my part # would be 90919-01249 not 01263.

They are less costly there and offer free shipping with code SHIPLEXUS while they are charging $6 shipping on Ebay.
They also offer periodic sales like on Black Friday and on 4rth of July.

So after my experience with old spark plugs, I would honestly really recommend them from OEM. I cannot speak for whether aftermarket is better or not, but when I first got the car I initially noticed how it ran much rougher upon cold starts and idling, more NVH than my dad's LS 460. I attributed this initially to sound deadening and the V6 running rougher, but at the next dealer service they told me I needed to change the spark plugs and the ones in the car were old. Night and day difference. Car runs much smoother now, much less vibration, feels more healthy.
