IKH22 vs IKH24 for Supercharged 4L

Hello everyone,

I know this has been discussed but I am still a little uncertain after reviewing the threads.

I bought my 2012 Tacoma with TRD supercharger already on it. Had about 30K miles on it in 2014 when I got it. I'm now at 65K miles and 6 years out from SC install. I've gotten the maintenance bug and thinking about swapping out new spark plugs.

From what I've read the TRD package comes with the

$9 Denso IKH22 Iridium Power Spark Plug, (Pack of 1)

Denso IKH22, gapped to 0.8mm. I've seen multiple posts that folks run colder plugs - most commonly

$15 IKH24 Denso 5346 Spark Plug

IKH24. What is the benefit of this and is there a risk? I do some towing but otherwise don't push it too hard. I'm thinking I'd be better off sticking with the 22.

Thanks in advance.
