Hungee Neutral Newbie October 28, 2009 Share October 28, 2009 Hi All,My Toyota stock spark plug (Denso SC20HR11) got the word "Iridium" printed on it. Does that means this plug is the iridium type like tout to last for longer mileage? ↡ Advertisement Link to post Share on other sites More sharing options...
Showtime Neutral Newbie October 29, 2009 Share October 29, 2009 unless its a fake which i doubt, it's a denso iridium and it should exhibit the properties of a denso iridium. longer life etc. As to whether the manufacturer claims are true is another matter.

Mattchlai Neutral Newbie October 30, 2009 Share October 30, 2009 (edited) IMO, there's no firm answer how far each spark plug can go whether they are normal or iridium or platinum coating. all the specs are on paper only. each driver has their own driving habit. so the best is to ask ur mechanic to check the plug condition periodically, ideally each service interval, or at least every 20k km.

It is good to get the mechanic to check some of these long life spark plugs during servicing of cars. Link to post Share on other sites More sharing options...

FYI, Iridium plugs can last well over 100KM under the right conditions. No fouling, under right self cleaning temp etc. One issue of plugs wearing out is the increase in air gap which affects firing. If you have been using your plug for a long time, you should check your gap. If gap becomes bigger, just regap lor. You can do so by gently tapping the plug on a hard surface. Get a gapping tool to measure. can be bought from Autobacs. Link to post Share on other sites More sharing options...
