3.3TT JB4 uninstall to clear Check Engine / P0050 code. Yanked plugs to check gap. Can i replace current Denso's with HKS 45iL with my list of current mods?

I posted another thread in the JB4 support forum a few days ago outlining an issue i was having with a check engine light and a P0050 code that would pop up every time i started the car following the install of my JB4. When uninstalling the JB4 i also ended up pulling my plugs as a precaution only to find that the kia dealership did not gap them at 0.022 as asked, they gapped them at 0.027!

Anyway, the check engine light went away after uninstalling and i regapped the denso's to 0.022 however i am going to get a wagner intercooler w/ charge pipe and air ducts, Ultimate Performance HFC downpipe/midpipe combo and was going to get the HKS plugs installed however now that i have my denso's out i was thinking of just installing the HKS and saving some money by not having the shop install them.

Right now i have AEM instakes, MBRP catback, and BMS OCC installed as mods. WOuld it be okay for me to install the JB4 again and replace the denso's with the new HKS? I have them gapped at 0.023-0.024.

I plan to plug my JB4 back in when i install the HKS plugs however i dont want to cause any more issues so im debating on just installing the HKS or putting the denso's back in.

Well since you are already doing the plugs, I suggest replacing it with HKS instead.

what do you recommend for a gap? i know most people say 0.022-0.024 however my gauge doesn't have ranges like some of them do i have exact gaps. I heard the larger the gap the better so i was thinking of doing 24 however i know they say Denso's gap at 22.

Do you follow the kia torque spec (19.6 - 29.4NM) or do you just do the good ole tighten until snug then a tad more?

C'mon - ALWAYS use a torque wrench and the factory-spec torque values!

I cannot think of any exceptions...
