Copper Spark Plug @ 40k km Usage

[Trex101]

just curious, is there really a great significant differences between copper and iridium spark plugs?

 

The iridium is so much more ex. Is it just as good to use those $3.50 ones from stockist? or will have the risk of misfiring?

 

thanks

 

Depend on your car model. Check your owner manual, if the manufacturer call for iridium it would be wiser to follow their recommendation because usually fine wire iridium require lesser voltage to jump the gap. Using copper might increase the voltage load required from your ignition coil thus more wear and tear on your ignition system.

i didnt really feel any great difference bet iridium and copper plugs...the reason i changed mine to iridium after running in my car was because it worries me to see the way some

mechanics in workshops change the customers plugs...they simply throw in the plugs and immediately tighten them using the compress air wrench without checking if the plugs are seated properly.

call me kia si but i dont want any screw up which could get my plugs threads damaged and later get jammed in the engine. with iridium i just change and forget for 80K unless there is something wrong with the plugs.

iridium is slightly ex but to me its worth it lah

I'm just pointing out that there is a technical differences between copper and iridium plugs, like i say before, check your owner manual and follow the recommendation, if it say copper then feel free to use it.

This is gross. There's no need to use air gun to tighten. Use plug wrench by hand will do. Even using hand can result in over-tightening of plugs. Best to DIY.

When alum alloy cylinder head is still hot working on it can be challenging. Have come across many young mechs will not start up the threading slowly instead immediate give few full turns to tighten up the plug - many end up with cross threads.

Hi bro, thanks for the highlight. I think the ignition coil is one part i did not relate to earlier. Now thats one cause of consideration to make when choosing the spark plugs

Very true din thought of this either. i think changing every 10k interval, the chances of less competent mechanics making the error is higher. one more valid reason to justify the use of iridium even though paying more...

On some cars, it is actually very easy to change spark plugs. Forte is one of them. I have always changed my plugs myself, it is only a 15min job on my forte. And my forte came with copper plugs so I have been using copper plugs since day one. I just get them direct from the stockist.

Hi, like to ask is there any different between NGK BKR6E-11 and NGK BKR5E-11?

I driving Honda Jazz 2007 GD model..and the car manual recommend NGK BKR6E-11..

[Mits_jc]

5E-11 is a "hotter" plug, recommend to use the default

stockists like min ghee offer better prices than buying directly with workshops

Its the heat range. 5 I think is a hotter plug so only good for short trips where yr engine dun get hot n u wun get carbon build-up. I use 6 cos I drive normally n some long distance driving too.

 

Too hot plug cud damage yr engine. Might get plug, piston or valves melt down.

 

I just stick to the original plugs my car came with n no problems at all.

Hi Bros, thanks for your explanation..will get the stocklist then..
