I did search before just to see what was said. But I do not do except any technicl data from this site with one exception, its form the knowledgeable people, or from someone who can present themselves in a proper way. So when I searched I found one of the topics to end in a fart war over something stupid,I got sick if reading through 5 pages of BS to get to reasonble response. Guess who was in the middle "chrisilversvt".

. Thats just one reason why I search elsewhere. Anyways I never did find any data from anyone who actualy used them and could claim yeah or nay. I am also someone that has Bosch+4s in my friends and I car and have 30-40000 miles on with no problems and both still getting 300+ miles to a tank. Know I there is evidence of premature failure with those, and I do beleive people have had problems, but since I don't its hard for me to come to a complete conclusion on the denso's or +4s. Once again its just my opinon. Flame away.
