Hello, first post here, for starters I apologize for bringing up yet another spark plug thread, I've looked through the various other threads and while I want to say "I know which plug to get", I really don't. (It doesn't help being on the neurodivergent spectrum either, forgive me if I'm just restating anything that's already been said in other threads.)
I recently bought my 2018 Stinger GT1 last month and come to find out the previous owner didn't do plugs when it was due, and it had the older 3 piece style ignition coils (Which were also corroded, causing a miss as well as the Audio popping issue), and figured I'd tackle it myself, but looking for spark plugs at the time overwhelmed me, and against my better judgment only replaced the coils knowing the plugs weren’t changed and possibly damaged by the old coils. Looking to tackle the plugs now, I honestly don't know which to go for.
From my understanding the OEM NGK's are dealer locked, which leaves my options as the NGK Ruthenium HX 95125 LFER7BHX, the HKS M45IL, or the Denso plugs. I understand that technically the HKS and the Denso plugs are mostly for those who are tuned, but I’ve seen in some threads that the HKS plugs could be used on a stock tune with the 0.28 pre gap it comes with?
Is it safe to say that I wouldn’t have any issues with the HKS M45IL’s at the pre gapped spec with the stock tune? I see that the newer NGKs have worked for some, and that others have had coil boot fitment issues? I’m not sure. I know that I plan on getting it tuned later, so I figured it wouldn’t hurt running the HKS and regapping later for the tune, or would that not be recommended? Some guidance would be appreciated as I get into this, I’ve always had the dealerships do work outside of basic maintenance but decided I wanted to finally get into doing things myself.
