Hello dear forum participants, would like to share my experience with my Hyundai i20 11/2014 trend in terms of spark plugs. In the service booklet the spark plug change is proposed after 160000 kilometers, which I have always thought to be utopian about cars of quite interest. As you can see, I have just slightly exceeded the 100000 kilometer mark and could theoretically drive 60000 km with the candles according to the Seviceheft. with spark plugs Champion RER8WYPB4 made a dash through the bill. I noticed already not too long ago a certain performance drop. At the moment after longer motorway rides strong deficiencies were noticeable with afterwards quiet drive in the form of strong hoppeln, and my first guess was the spark plugs, what should I tell you I was exactly right. I replaced the old candles by Bosch Iridium Double today, he purrs again like a kitten. The 160000 km Are you sure they’re very questionable? I started a few pictures of the old candles.
