This review is from: Denso 5305 Iridium Spark Plug , Pack of 1 (Misc.)
I fitted this plugs into a Chevrolet Spark a while ago, haven't caused me trouble at all. Thought i had to adjust the gap of the plugs ( since usually new ones are a bit separated), starting the engine became faster and warming too, felt the acceleration somewhat stronger, fuel economy is a bit higher than OEM ones ( think this plugs might work better into bigger engines) but as I told you already they are doing great no foul ones, and burning equally.
