spark plug iridium

[CLAVEL3699]

the only difference in specs would probably would be the heat range of plugs siguro... bawat model ng engine kasi ng vehicle meh specific heat range...

if the first 3 grooves ng thread is blacked, its ok, anything less than or more that (less than 2 grooves/ mroe than 3 grooves blacked) eh detrimental sa life and performance ng plugs...

ito probably and sinasabi na out of specs that eventually will lead to failure...

True... Tama ka sir.

Aside from their longevity, what other benefits to I get if I upgrade my stock plugs to iridium? Do I need to replace anything else in the engine when I do this?

you dont need to replace anything else..... spark plugs are plug and play, kung tama ang specs and size.
aside from longevity, i think much smoother ang acceleration, although hindi naman masyadong noticable.

try niyo baguhin gap ng spark plugs.

napansin ko mas smooth acceleration kapag above 1.1mm yung gap.

adjusted yung sakin ng 1.3mm.

2NZFE at 2E engine nga pala.

stock gap ay 1.1mm.

So guys,

Ano ba, in your opinion ang best type of spark plug when we talk about performance and fuel economy? Longevity factor aside.

Copper or Iridium?

1d4lv,

OEM plugs have a gap of 0.8mm. The iridium equivalent is 0.6mm. Is that good news or bad?

[innova2013]

based on experience mga sir. share ko lang.

if narrow gap ang spark plugs, no/less misfire on high revs and better idling. (better drivability)

wide gap naman, better acceleration response at mas maganda ang power sa dulo. (more on performance)

kaya mapapansin natin sa owner's manual, kapag 1.3L and below ang engine capacity wide gap ang spark plugs kasi kulang sa torque (1.1mm and up). kapag 1.4L and up naman, narrow gap (0.8mm and below)

difference ng copper (regular plugs) sa ibang metals na ginamit ay durability lang talaga bago mapundi (busted spark plugs), over all same performance. pwede naman subukan, OEM plugs and iridiums or platinums.

hindi din naman natin agad agad mararamdaman na hindi na maganda performance ng spark plugs natin depende na lang kung busted siya (palyado/rough ildling yung makina).

Innova2013,

Thank you for your insight. I just might be interested in upgrading my plugs in the next PMS run.
