NGK Iridium IX vs. NGK Laser Iridium ?

[JaYson]

Hey all

before anyone jumps down my throat, I've been searching for hours and cant find any specifically about these 2 products. people seem to just speak generally about NGK Iridium, not specifying between the IX or the Laser series.


just wondering what everyone's take is on these 2 products, and the differences between?


From what i gather the NGK Laser Iridium is what was used as the OEM plugs in the Mazda 3s (mine: 2006 Mazda3 GT 2.3L)


NGK Laser Iridium:

- OEM style
- smallest iridium tip ensuring best durability
- Longer life Plug due to the use of Platinum Pad
- upwards of 120,000KM life

Mazda OEM: aprox. $22.90each (assuming mazda oem is infact the same as the NGK Laser Iridium)


NGK Iridium IX:

- Next best to Laser Iridium
- Smaller Iridium tip ensuring good durability
- lacks a platinum Pad; meaning shorter operating life due to oxidization
- roughly 60,000KM life

Canadian Tire; On sale: $8.02each (but you would have to buy 2 sets to equal the same operating life so: $16.04each)



so if anyone has some more insight or an verify the above that would be Greatly appreciated.
1) also is it a possibly a benefit to go with the NGK Iridium IX and replace them twice as often for less money? because the longer lasting NGK Laser Iridium plugs deteriorate throughout its longer life. and putting in a fresh set of Iridium IX twice as often is better anyways for less $$$ ?


Thanks in advance

anyone? no thoughts?

NGK Laser Iridium has the smaller electrode size compared to the 0.6mm tip on the NGK Iridium IX.

based on the fact that i've sourced the 2 products out to about a $10.00 difference between the two for a 120,000km duration. its all about performance. any insight would be awesome.

laser iridium is MUCH better because it really can last 120k, whereas iridium ix lasts less than half that... you get what you pay, and because the iridium ix wears faster, your gap grows faster and the performance decrease is sooner than laser iridium which gives you consistent spark for at least 100k

the finer tip is also better as it allows the spark to jump easier

iridium ix is just a marketing thing NGK USA wants to push because it's cheaper and more attractive to cheap people... interestingly, NGK japan pushes laser iridium instead because it truely is better

Don't know for sure about the IX iridium, but when I had my old sedan, I replaced the plugs with the laser series and immediately felt the difference. Plus, fuel economy went so much better. I'd spend the extra because you'd probably be making up for it in the long run anyway.

Just my 2 cents. :)

I would just use the same type that your car came with.

For me, I have a 2007 Mazda3 GT sedan 2.3L which uses NGK (3811) ILTR5A-13G Laser Iridium. Bought mine from Amazon.com (US site).
