    Need to change my spark plugs, what are the best ones? Do I need to do anything else at 115k miles in the spark plug realm?

    Check your lower ball joints, transmission fluid, and replace your fuel filter.

    I changed from Denso IK22 on my supercharged engine to BOSCH double iridium 9610 plugs because just after 5K miles I was beginning to see erosion like this. This document looks to explain why the 5VZ-FE wears out the driver side plugs differently verses the passenger side.
    http://www.dragonfly75.com/moto/plugpolarity.html

    Using a spark plug heat range cross reference chart the BOSCH double iridium plugs 9610 have the same heat as the IK22 plugs.
    https://www.amazon.com/gp/product/B00515NIN0/ref=ppx_yo_dt_b_asin_title_o03_s02?ie=UTF8&psc=1

    I only have 1000 miles on the BOSCH plugs so I can not comment on longevity but there has been no indication of detonation or pre ignition on my S/C engine so the heat range seems okay.

    That plug polarity article was pretty interesting. Thanks for posting it.

    That's a diagram from the Toyota parts catalog. Either the website has the wrong diagram or the parts catalog used a generic diagram for all engines. Only the 96-97 4 cylinders had a distributor I believe, so it seems odd for that diagram to be used. But toyotapartsdeal is very good at verifying correct part fit by VIN. Seems like they interface directly with the Toyota electronic parts catalog. The only difficulty is verifying a part by name if Toyota gave it an obscure name.

    My v6 only has 3 plug wires that travel over to the driver side spark plugs. The other 3 are fired directly off the 3 coil packs that mount directly over the pass side spark plugs.

    Platinum plugs on a force induction engine is a big no no.
