What spark plugs for 4.7 L V8 4runner?

My dad's friend has a 2003 4runnner SR5 V8 4.7L - she wanted a recommendation on the right plugs to buy. When I looked up the plugs on sparkplugs.com, I got these two options:

Denso Double platinum 3128 PK20R11 .035" (OEM)
$6.89

Denso Iridium Long Life 3297 SK20R11 .035" (OEM)
$9.35

Which should I suggest she get? I'm just using sparkplug.com because they have an easier lookup function. I like RockAuto.com for prices.

It came with iridiums. I would put iridiums back in it.
