NGK Iridium IX vs Laser Iridium | BobIsTheOilGuy The Laser Iridium plugs have a wider center electrode, whereas the IX has a more narrow one I think that's why the Laser Iridiums last longer as well as the double precious metals, iridium on center electrode, platinum on side electrode I've had friend who bought the IX and worked well, but it's longevity AND performance that I look for
Iridium vs Ruthenium spark plugs | BobIsTheOilGuy 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 them as a maintenance
Do I really need iridium spark plugs? | BobIsTheOilGuy So my car is due for plugs, and the stock replacement iridium and CA emissions specific plugs are $15 each, even from discount sites However, there are alternative platinums (which are also NGK just like OEM) for only $5 each I know iridium lasts longer than platinum, but I don’t plan on
Denso Iridium TT vs long life, which one is better? 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 the ground The Long-Life series
iridium plugs. do they make a difference | BobIsTheOilGuy Copper or iridium plugs alone, used with stock resistive wires, make minimal difference (from the minimal resistance difference) Modern engines may benefit more from the more durable iridium which allows making the electrode smaller for a very slight increase in combustion speed
PLATINUM VS. IRIDIUM | BobIsTheOilGuy Platinum and iridium will last a long time But iridium is better because it conducts better than platinum Actually, plain steel plugs [when brand new and sharp] have less resistance at the tips than platinum The new precious metal tipped plugs have a benefit in that they are quite small, and let gas in and out of the critical area better
Platinum or Iridium Plugs for OPE? | BobIsTheOilGuy The only reason platinum and iridium spark plugs are made is for vehicle engines that run hotter, leaner fuel mixtures to meet emissions control requirements AND have a long service life while doing it! Garden equipment applications simply can't push conventional plugs hard enough to make a difference!
GM 5. 3 owners - MPG and Iridium plug question. Hello, First question - for anyone running a 00 + Tahoe Suburban, what do you typically get for MPG (summer and winter) Second question - In September, I removed the original Platinum plugs in my 01 Tahoe, and had the replacement Iridium plugs installed Without doing a 'scientific' MPG
NGK V-Power or Iridium? | BobIsTheOilGuy Hey, I would only go with the factory iridium spark plugs or the ones specifically listed in the manual unless something has changed or GM made a mistake (unlikely) Looks like you need AC Delco 41-985 According the spark plug manufacturers, standard copper plugs can go about 30K, platinum plugs go 60-100K, and iridium about 120K These are general values and will depend on what the car
