Review: Good performance and better gas mileage. - The plugs I received were made in Germany. The plugs are almost half the cost of Denso and they perform just as well. I would recommend these plugs.
Review: Solid, reliable park plugs - I got these for my 2002 GS430 and boy do they help get all the power out of my engine. I have an exhaust leak and trans leak that leads to a laggy bogged down performance, but by swapping out with these plugs yearly I can keep the power more responsive. I tried other plugs, but these seem to do the best for me in my case. Installation was straight forward and these tightened in place great with a little bit of antiseize.
