[QUOTE="PistolWhip, post: 15620130, member: 30361"] His tuner is definitely not "incorrect." BR7EF's are absolutely the right plug for that set up. Yes the 7EF and 7IX are both heat range 7, one step colder than stock, but Iridium plugs aren't always the best choice. Both will work and both can be considered "correct." I run BR7EF's, have for a while now with no issues. I've run Iridium plugs, Platinum plugs and Copper plugs of all different types. When you start making a lot of power with boosted applications, you're going to want to change the plugs more often regardless of what they're made of. I chose to stick with the BR7EF's since they perform very well and are cheap to replace. The 7EF's that are in my car now actually replaced IX's and there is ZERO difference in noticeable drive-ability. [/QUOTE]
