Went to the mechanic to replace the spark plugs, silly me trusting what was received from Amazon is the real deal. Technician removed the old ones, grabbed the new ones to drop them in. Plugs had the correct part number "Denso IHK22", all correct packaging but did not look right (will try to upload pictures) they had defects, cannot be gapped and two of them had damage on the thread, conclusion fake Denso plugs. Ended up reinstalling the old ones.

I just saw this thread, but it seems you're on the right path. Maintenance will be absolutely key, especially with a SC installed. Spark plugs, air filters and engine oil will be critical to monitor and change more often than standard recommendation. Given the dusty climate, I think air restriction in a dirty air filter could have been one of your main issues. Changing the plugs with whatever plug your SC manufacturer recommends would also be a great idea. I'm not sure if you use the same plugs with a SC installed, as you would with the stock engine?
