I changed my plugs recently and qent with NGK Ruthenium gaped a step colder and they are working well for me, seem better than Motorcraft but thats just my opinion.
Pros: working well, better than Motorcraft
I just did the 30k service and my mechanic recommended these plugs. They are expensive, but worth it.
Pros: worth the cost
Cons: expensive
Mileage: 48280 km
Stick with Champion plugs in the 4.0L inline 6. Anything else will have you chasing a “stumbling” idle.
Pros: prevents stumbling idle

I use champion on my 04. No issues. The more expensive ones that’s when the issues start
Pros: no issues

Use the Toyota OEM iridium tip plugs. They are amazing!
Pros: amazing performance
Vehicle:

I have a had a couple of NGK spark plugs with very fragile ceramic insulators over the last few years. I suspect like everybody else they are cutting on QC due to that inflation that officially doesn't exist, especially for made in Japan products.
Cons: fragile ceramic insulators
Make sure if you purchase spark plugs that it is not Auto Light. They tend to mess your vehicle up more and not work well with Toyotas.
Cons: mess up vehicle, not work well
But yeah, switch to another brand and stop using champions.
Cons: stop using champions
