Does Spark plug increase performance ??

[Enforcer533]

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 ^^

Spark plugs are wear and tear stuff that will degrade over time, so changing them will definately have difference but it more like the power is restored rather than power is increased. Just like changing a new toothbrush..

 

Different brands and types will determine how long it lasts that's all.

[Edca]

For me, I can feel the difference. Base on the responsiveness of the engine and use the correct plug.

[Mini-itx]

Yes, its does but don't expect massive difference. There will be slightly differences like better engine respond, smoother engine etc. But its slight.

[Zuoom]

actually no.

 

it just brings out the best of what the engine can offer.

 

that alone would hardly contribute to any noticeable gain.

if any, a change to fresh regular plugs will work just fine.

 

just remember to use the correct heat range.

too cold, the idle will suffer and you get a build up of carbon (unless you rev it off).

too hot, the engine will misfire on high revs.

[Ehchang8]

[Zac]

I believe Spark Plugs are for performance, or fuel economy.

[Archangel]

sparks are not too expensive...so i rather replace on recommended interval that is 40,000km using oem sparks

[S-gt]

Does the diff and it will be smoooooth acceleration/ i.e good pick up due to its characteristics, efficiency of burning it. Do enjoy the ride.

Most obvious symptoms:-

Difficulty in starting

Rough idling

Slow acceleration

Poor fuel economy

Sometimes corona seen around the spark plugs in the dark

Spark plugs sooted/wet when extracted for inspection

Cause they want to earn $$$.......

 

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.......
