Gonna pick up some new plugs before James comes to town and Ed had suggested either Denso IT22's or NGK TR7ix's. Was also wondering about the Brisk GOR14IRY's as well... I know that Brisk plugs used to be the "newest, greatest thing ever since sliced bread" but then some people had reported issue's with them. Have they gotten better since reported failures, or were most of those due to other factors than the plugs themselves?
