Sparkplug: Copper or Iridium?

[radz15]

Para sa celerio mo ba? Every 10k dn ba palit ng suzuki sa PMS nila?

If you're replacing plugs every 10k or 20k, copper plugs should be fine.

In reality, copper has the best performance of all three and the worst longevity. Platinum has good longevity and the worst performance. Iridium has good longevity and a performance that is decent, which is why iridium plugs tend to be more expensive than any other type.

DIY Cleaning spark plug using softdrink and salt. it works for me...

[jick.cejoco]

Spark plugs of the right heat range and the engine at optimum performance should not need spark plug cleaning during its service life. If they get fouled like the ones our expert showed, it is a result of poor mechanical condition, poor fuel delivery, weak ignition coil output, high secondary resistance, bad fuel, restricted air intake. Correct the problem at the source

Oo tol. Every 10k sa suzuki. Pero pag Iridium daw every 50 or 60k

Sir radz,choose the copper plugs. Replacing more often is more better than the iridium high life kuno that can be use for more thousand/s of kilometers. Pero manggugulo lang ng konti my APV consumes less fuel when I started to use iridium plugs.a difference of .5 - 1km to a liter. Kaso Iridium plugs cost around 2k per set unlike the copper plugs which is around 115 per piece sa suking auto supply.

for for the OEM recommended plugs. I've known cars na nagbago ang engine response to bad because of using non-recommended plugs.
ditto with what jick said.

[jick.cejoco]

Today's cars with tightly packed engine compartments will opt for longer life spark plugs due to the cost of labor for routine replacement. The removal of plugs for cleaning becomes a waste of time and use of the car. You might as well replace them when bad but fix the cause of the spark plug fouling. Cleaning them without investigating what is causing the carbon build up is only masking the result which becomes a chronic condition

Sir based sa manual ko meron nakalagay na oem plugs for copper and Iridium. Ngk for copper, denso for Iridium

Interesting, tingnan ko nga if may fouling sa lumang plugs ko.

I noticed that my car recommends only iridium plugs. Thus iridium ako

[red_one]

Our Mitsubishi ASX has iridium spark plugs as well.

According to the owner's manual, I need to replace at 100,000 km.

[baludoy]

Saan ba kayo nakabili ng ngk iridium sparkplugs? Sa ace hardware kasi by order pa tapos 1 week ang waiting time

[kimbon]

dami sa banawe kung taga QC ka, manila sa recto corner masangkay, 10th ave. kaloocan or sa suking mong auto supply.

I use Copper plug with 2MM gap.

But im using my own design Multiple Spark Capacitive Discharge Ignition system capable of 30KV 5 spark per cylinder at idling rpm.

[Adolfsden]

I prefer copper, good conductivity compared to iridium and platinum. Though you will need to change more frequently compared to the other two. Just my two cents...

Cheers

[StockEngine]

Iridium alloy has almost the same conductivity as copper. They dont just use iridium per se...

[dr. d]

if you have to "remove half the engine" just to get to the sparking plugs, best you use plugs that "last longer", i.e., iridium.
otherwise, copper is fine.

now where did i read, that there are two kinds of iridium plugs..? one is supposed to be replaced just as often as copper, and the other that has a much longer recommended replacement schedule... can't remember...
also, "beware of fakes." iridium as well as copper.
