2018年7月15日 · What would be a reasonable Iridium Plug change interval? I have Denso Iridium Power II's, which Denso rated for 30k miles back in 2014 or so when I put them in. I rechecked and now Denso Europe gives them just 20k miles. I heard a lot of people claim 60-70k miles on them are no problem. Now the...

2010年4月27日 · The TT series is the aftermarket adaption of the Super-Ignition Plug Denso created for the Toyota D4-S engines, minus the side electrodes. I’ve used the Platinum TTs in a Subaru, haven’t tried the Iridium TT. Denso seems to push them more than Iridium Power. iridium TTs have platinum on the ground electrode, like the OE plugs. Platinum TTs use titanium on …

2015年5月10日 · There is little I can find about Ruthenium spark plugs, except it's the new sliced bread, better, last longer, etc etc. If the Laser iridium have indeed only one iridium (or platinium + iridium) pointy electrode, I can see the Ruthenium lasting longer. So, what's your take ? Can you educate me on spark plugs ? On most 4 cylinder they are real easy to replace so I always …

2006年11月20日 · Visiting the NGK site left me confused. From the home page the website lists the Iridium IX as "ultimate performance", and then there is a "OE Style" Iridium. I'm used to seeing "Laser Iridium" on parts lists everywhere. And its been suggested that the laser iridium spark plug is superior, more...

2012年10月8日 · The manual calls for Denso Iridium Long Life plugs to be changed at 160k km. Cars at 320k so second swap and I noticed Denso has new TT plugs with smaller 0.4mm center electrode as opposed to 0.7mm in long life. Previously 0.4mm center electrode is for the "performance" plugs and generally...

2015年8月14日 · I am getting NGK Iridium IX, I have heard some say that I shouldn't have to gap them, but if I do, is that the proper way? I know some folks say that you can damage the electrode if you do it wrong.

2002年8月5日 · From what I remember the older 0.4mm iridium plugs last about 15-30k miles, but the newer 0.4mm Denso Iridium TT claims 100k miles life vs the 80-100k miles life the 0.7mm Long Life Iridium. They are also cheaper too.

2002年12月22日 · I have a Briggs and Stratton 5500W generator with the Briggs 342cc engine. The owner's manual calls for a .030 plug gap for plug. The factory plug is the Champion RC12YC. I purchased an iridium NGK BKR5EIX-11 plug to replace it. Out of the box the gap is .038 for the NGK. Should I reduce the gap...

2007年7月2日 · Iridium more or less the same as ordinary copper core resistor plugs. Again: it never seize to amuse me as to where these "info" comes from RE: iridium has higher resistance than copper core, etc. Q. Remember 1 thing: regardless of how relatively exotic the materials used in automotive spark plugs these days: your electronic ignition system on your gasoline …
