3RZ-FE engine Spark Plugs & Coil Wires (question about which specs are important)
Just curious if it even matters which NGK spark plug to use out of the replacement list?
I think the original plugs for the 3RZ-FE are Nippon Denso ND K16R-U, gapped at 0.031" (sometimes listed as 0.032") at 14ftlbs (dry, at no anti-seize) torque.
The NGK web site lists suitable replacements as
1. Standard NGK BKR5ES
2. OE NGK BKR5EYA
3. GPower NGK BKR5EGP
4. Iridium NGK BKR5EIX
5 Ruthenium NGK FR5BHX
Pricewise, they are roughly equivalent given there are only 4 of them and they're pretty inexpensive so the question isn't at all about price.
Which works "right"?
Presumably, all the marketing aside, I can't go wrong with OE.
But does anyone have good or bad experiences with the other variants?
(And, yes, I will avoid Bosch at all costs.)
Same question about marketing with the sparkplug wiring loom.

1. Local Toyota Dealership $150 (out of stock, 1 day away)
2. Camelback Toyota Dealership $83 (in stock, days away)
3. Local Parts Store $42 (in stock)
If I buy it at a parts store, what brand (NGK?) do you generally recommend?
The original owner said the current four wires were put on about a dozen years ago and that they're from a parts store in another state.
The labeling says "Belden Premium 5mm cable SAE Class F-KI".
Does the width or SAE class of coil wires even matter?
