Interestingly, they were gapped at about 3.8, so I re-gapped them at 4.3. I had already bought some Last platinum, so well see how they go. Last Iridium, however, is more expensive. The problem with the NGKs is that the ground electrode erodes. Actually, the Laser Platinum is like 14, while the Iridum IX is like 9.

To ensure optimum performance please consult your owner's manual to determine the correct spark plug for your engine. Hey, I would only go with the factory iridium spark plugs or the ones specifically listed in the manual. I have noted that NGK Iridium IX does not last longer as compared to Denso Iridium Power. Electrode Material: Iridium and platinum.Pure alumina silicate ceramic insulator provides superior strength and better heat transfer.

#Ngk iridium ix vs laser iridium series
The advanced design of Iridium IX Spark Plugs features a 0.6 mm Iridium center electrode tip for superior ignitability without sacrificing durability. The IX series is a single fine wire, meaning that there is only Iridium on the center firing electrode, where as the Laser has this on the ground and firing. The NGK Iridium IX provides only 40 to 50 thousand miles, and the NGK Laser Iridium provides twice. Ruthenium Vs Iridium Spark Plugs Ngk Said Ruthenium No Advantage Except. Many things from manufacturing to handling can adversely affect the gap.NGK Spark Plugs are designed for improved ignitability and throttle response. midjourney discord link x x The most common reasons an Audi A4. Also, if you don't even check the gaps you have no idea if what you have been given is even indeed. But it certainly makes me feel better that I am gapping it per the OEM spec. I also looked into this some more and read some articles on this issue and basically again I think the whole point is if you are going to gap any plug to make sure to gap it carefully using a gapping tool and not pry on the electrode to open the gap. The resulting misfiring would trigger a check engine light.

If you opened the gap on the platinums, this is likely why they failed so quickly. The platinum tip is vulnerable to scratching or other stress, which could cause a failure or loss of the platinum tip under high cylinder pressures. Platinum plugs require careful handling when gapping them. I checked out that article in Road and Track which states the following:
