This review is from: Bosch (4428) FGR8LQP0 8 Platinum +4 Spark Plug, Pack of 1 (Misc.)
I bought these to replace the OEM plugs in my 2003 Honda Element, at 102,000 miles. I had used these in my Honda VTX 1800C motorcycle as well and I've always had good results. Like oil and tires, plugs can generate plenty of controversy. I can only say that they work very well for me, as well as OEM when it comes to performance and MPG. In the VTX1800C, they foul much less often than the original Denso plugs, but this would NOT be an issue in an otherwise healthy Element. I'd recommend them without reservation for the Element or the VTX.
