• * Halfords and Halfords couriers deliver Monday to Saturday excluding bank holidays. A regular spark plug uses a copper central electrode whereas an iridium spark plug uses, you guessed it, iridium. The tapered ground electrode increases flame kernel expansion, while the superior heat range design is ideally suited to the demands of high performance environments.

  For the most part, a new set of plugs at sort intervals is like washing your car-it always feels a little 'faster' after you are done. p>

  Late or missing payments may have serious consequences for you and cause you serious money problems. Not only are these fake plugs not manufactured and tested to the same degree of the genuine item, they don’t actually feature any ‘iridium’ centre electrode tip at all! For example, on some part numbers, NGK now uses Laser Etching instead of stamping, so the font information may not be accurate. NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark.
  
  ish) machined down nickel tip is definitely not a great idea and is likely to wear out far quicker than that of any OE standard ‘copper-nickel’ plug.

  Late or missing payments may have serious consequences for you and cause you serious money problems. Sometimes I have felt a little more fluid transition thru the midrange when a new set of plugs goes in, but it doesn't last long.

  Just be aware that there may be other counterfeits around that look slightly different, but the main principles are the same. Iridium plugs are more expensive than copper but seeing as they last longer and offer a more consistent performance throughout their lifetime, many bikes opt for an iridium ‘upgrade’. You can use this weight as a guideline to measure your suspect CR9EIX plugs, the fake plugs were 155 grams in comparison. p>

  Fakes are also known to not feature any copper core which means they retain heat and can eventually meltdown, it’s likely to be the same with these fakes. One thing I can say about the CR9EIX is that my bike idles until warm without cutting out a couple-o times as they do with the CR9E's (standard).

  The likelihood is that they will possibly work, however it’s a huge risk and should be remedied at once. Copper is generally seen as being the best metal to use in terms of conductivity but iridium plugs are seen as premium as they last longer than standard plugs and can be built with smaller tolerances. the real thing you are looking for is no erosion of the center electrode and a light grey, or even tan color of ash/deposit on the spark plug.One of the best parts of this whole investigation is that we of course found out the fake plugs don’t feature any IRIDIUM tipped centre electrode at all, it’s all LIES. Fake plugs are known to have air bubbles trapped inside the white ceramic insulator which can affect heat dissipation capability. The smaller electrode on iridiums means less flame kernel quenching and thus better firing of lean mixtures. Iridium is far harder than copper and this allows the spark plug manufacturers to create a plug with a sharper ‘tip’ which better focuses the spark around the centre electrode without compromising its service life. The longer the "throat" the farther heat has to travil to get to a cool area and the hotter the electrode will be.
