There has been some controversy on here regarding the shorter warranty period on NGK spark plugs as of late.
Now, NGK only gives you a 60-day warranty. People on here seem to think it only applies to Rock Auto, but that is not the case. The warranty was shortened effective May 1, 2020.
I looked at both Napa and Advance Auto Parts, and both stores also have only a 60-day warranty. When you look up any NGK spark plug on AAP's site, it will say 60 days
