True, but the point is to not have to order online and wait for 3+ days just to get spark plugs and that goes for the dealer as well. Sometimes they need to order non-resistor plugs and the price per plug was something like $ 7.68. So why hassle when you can just go to pretty much any local parts store and buy some resistor plugs and make your own? Actually, making your own costs less and takes less time than going to the dealer or ordering online. I'm fortunate to live 5 mins from the dealer, but not many other members have that accessibility. So this is something to help out those that want the convenience and cost-effectiveness of making their own non-resistor plugs. By the way, I did notice a much smoother performance once I took out those resistor plugs I previously installed. My remote start would take 3-4 tries to crank the engine, now its just one....maybe 2 if the engine is cold and sat overnight.
