Despite all the negativity around the E3 plugs I had to try them because they happened to be on sale last week at Canadian tire for $10 a pair. I have used them for about 500km so far and no problems. I have noticed a slightly better throttle response, under WOT it seems a bit smoother and it got rid of my hesitation that I had noticed for the new driving season. I will try and see if my fuel millage is affected at all but will come on a later date.
What i have noticed so far they are defiantly better than the stock Bosch platinum sparks with a 100,000 km
