Does Spark plug increase performance ??

[Swordwind]

hmmm..i just checked the used ones, they are denso k16pr-u11. what kind are these? haha.. thanks in advance. : )

Normal copper plugs don't last very long due to rapid wear compared to platinum or iridium ones.... However, they can simply be gapped and you can resuse them again.......

All in order on my previous Kelisa, the copper electrode spark plugs after 50,000km did not need to re-gap the spark plugs (almost like new). I believe Iridium spark plugs can be overkill for some people to use them (waste money?)

I believe if engine in order like my previous Kelisa, after 50,000km copper electrode spark plug gap same as new. I believe Iridium spark plugs not that useful for some motorists (wastage)

if you are not supercar or performance type.. i think no point...

[Qr25vet]

for track,best is to use a colder plug that what u normally do on the roads. thats what i learnt cos u're usually @ the higher RPM range and engine temperatures are higher than normal on track. best is to try out a few heat ranges from the stock heat rating...maybe 1 or 2 numbers higher or lower depending on your preference.

Any Spark Plug to intro, intend to change one,

 

I driving FD 1.8 Civic

 

Denso which one is more suitable?

SMS M X TRADINGS or ask Terence at their website, he can advice you.

Hi all

 

 

I heard alot of rumours that when you change a spark plug it

increase your engine power is it true ? i had a friend who change

to denso iridium sparks on his vios and he feedback to me that his car

feels more powerful. i seriously had doubt in it. can some kind souls

share his expierence when change to denso plugs ^^

 

If spark plugs increase engine power, then I think everyone will be changing plugs like changing pants.

 

Don't be fooled. If anyone says that, ask him to dyno and show u results. I thought this myth had been bustered long time ago? Still got people peddling koyok in this era?

 

Plugs, air filter should be changed yrly and strictly use oem recommended plugs. One plug at most $6...

[Lammy84]

plugs have heat ratings, on highly tuned engines, "colder" plugs are recommended so u can prevent pinging(pre detonation)

Agree. I just switch back to normal copper servicing recently.

haha my friend was like saying after he put the Denso

his car pick up v fast keep on asking me to do it

lol till now i am still skeptical about it

[Iygnaug]

since we are on spark plugs discussion,

how about thicker spark plug cables(or some call it octopus)?

is it also koyok?

Check out FD forum. there's this ongoing discussion on IK22G plugs suitability for non Rs. Seems like not too bad. Maybe ya can try it after some of the ppl there monitor it

Denso was my last pair of plugs used. Not much different and it was supposed to be longer lasting since it is iridium.

[Mcf777]

i changed my spark plug yearly or around 30-35K (dont know whether it is platinium or iridium).

u will feel the car more powerful and wanted to chiong forward

Spark plugs and plug wires (for older cars not running COPS) are wear and tear items. If your car is stock, then using OEM replacements is good enough and changing it when required is sufficient to keep the vehicle in good running condition.

 

Those who claim perceived improvements without any hard data backing it up I will take with a huge pinch of salt :) Unless of course you like to spend money and then delude yourself there is an improvement, by all means, nothing wrong with that since it is your money and ride! :)

[Mini-itx2010]

No, spark plugs alone does not contribute much to performance. You have to look at the ignition system as a whole. A more powerful ignition system will allow you to tun bigger gap. And this gap is what is critical to your performance.

 

If you want to maximise the performance from your plugs, you can try opening up the gap a little (~0.01 inches) and try to see if there is any effect. I have done that before and I can tell you that you will notice a stronger low end. At low RPM, engine will be more lively and more powerful.

 

However, this may cause your high RPM to misfire. I.e. no sparks. This is because the stock ignition system is unable to create high enough voltage to cross the gap and create a spark. Why the RPM difference?

 

Different coils have different rise time and charge time etc.... There is also air/fuel in the cylinder. A spark is easiest to create when there is complete vaccum. As the amount of air/fuel increases, its gets harder to spark and higher voltage is required. If your ingition system is unable to provide this voltage at the required time, then no spark will be created and hence misfire.

Yup. Not much different since I am now back to stock copper plugs.
