FJT at Rowell Road. $12/pc for NGK. $15/pc for Denso.

 

 

Just DIY myself. NGK Iridium is good value for money. Improved fuel consumption compared to stock Denso plugs.

 

You can get wrench at Mustafa.

 

Bro, that denso is which model ? U24### isit? if it is.. that would be $5 a pc.. been using it for my Version R. It does affect the sound from your exhaust. More bass.. compare to NGK.

[zanwoocheh]

Ahboy have NGK wires?

 

have. That's a necessary item for plugs. Just bring the Salesman over to your bike and show him.. they probably have another name for it. haha

@zanwoocheh

Sorry for the late reply as I didn't realise my post on a group thread was moved here by a mod... zzzz....

 

Anyway, if it's a $5 plug, it is not Iridium. Denso Iridium is more expensive than NGK Iridium. If I'm not mistaken, the Denso Iridiums are sold at $18 or $20 per piece. Is Denso Iridium going to return 50% better performance than the NGKs? I don't think so. That's why I went for NGKs.

[zanwoocheh]

oh denso iridium. thought you were talking abt the normal denso plug. alright great.

hello guys, just wanna check. ive read here that the iridium spark plugs are the best. in terms of lasting at least. but curious...spark plugs are universal right? say from a spark (the bike) to S4 to Haya to Duc or anything...

Black plugs has nothing to do with iridium or other types. It is caused by your over-rich fuel mixture. Adjust your carbs accordingly.

No, they're not universal. Check your bike manual for the correct type codes. FJT should also be able to tell you which ones are right for your bike.

woah, thanks a lot! i shall go read those links first anyways.

It shouldn't drop. Wrong plugs for your bike maybe? Could also be high tension cables not inserted properly into the plug resulting in irregular firing.

[ludacris10]

You can google it bro. You'll need the spark plug opener head and a ratchet(Or a long bar)

Depends of what bike you ride. On some bikes like the Super Fours and most 2B bikes, the spark plugs are easy to reach. Bikes like the RSV4 is a pain in the u-know-where... After removing the petrol tank and whatever else is in the way of reaching the plugs (e.g. air box), remove the High Tension cables connected to the plugs by just tugging at it. Then you need a spark plug wrench to remove the spark plugs. Your bike standard toolkit should have the wrench. Otherwise, you can be buy one at Mustaffa.

 

Here is a good guide:

Oh, Spec 2 is quite easy. Just remove the petrol tank and you can see the plugs already.

But you definitely need the wrench...

If I'm not mistaken all the Super Fours use the same plugs. I'm using the CR9-EHIX and it was recommended over the CR8EHIX because the CR8 runs hotter.

 

I'm also doing KL-SG-KL quite often and my speeds are usually in the 160-180 range as I like to ride at night when there's less traffic.

Generally plugs can last a long time. In those days when plugs were generally plated copper core, all you have to do is to clean the plugs every 10-15000km on cars, check the gap, fit them back and you're good to go.

 

The Iridiums on my bike have been run for about 15,000km now (about 10 months). With modern technology, they are "self cleaning". The performance on my bike (Revo) is still good with these plugs. I will probably check them at 20k or 25k to see the condition. I expect that they should be able to last at least 40k provided they are not fouled by overly rich or lean air/fuel mixtures or oil due to bad piston rings.

 

As they only cost $12/piece I'll probably just change them at 25k or 30k. My maintenance routine is not to to wait till a part actually dies...
