The Denso iridium tt spark plugs have out lasted and out performed any spark plug that I have tried. I have them in my honda crx with 416k miles on it and in my Nissan Cube 2009 with 130k miles on it. I changed my plugs at 100k miles on my honda and at 100k miles on my cube. I get better gas mileage and performance during the entire life of the plugs. There were ngk iridium in my cube when I bought the cube, but two of them went out at 28k miles. I read such good reviews on the ngk plugs, but I am going to have to disagree with the majority of ngk lovers out there. I do not think that ngk is total junk, but I do think that the plugs are greatly overrated. The Denso iridium tt plugs are as strong as it gets. I belong to a group of cube owners in TN and I along with 114 owners out of 136 total run Denso iridium tt plugs and love em. The ngk iridium plugs do not last no 100k miles like people claim they do. Most people change their plugs way before a 100k miles. If a person wants a plug that will give persistent performance along with a long durable life span than the Denso iridium tt plugs are the one to get.Read full review
