Performance Spark Plug

[Happy_nathaniel]

thx vtim n the rest.

1 more thing, if what trex101 said is true, then there will be saving of fuel, isn't it?

i came across the toyota brochure, i interpret that with iridium it help to reduce fc. so i'm quite confuse

[Trex101]

Even if it does, it's quite small & not really measurable. I perfer the fine wire type mainly for it's performance, longevity & smooth idling.

[Vtim]

the iridium plugs will be slightly more efficent and that in turns the engine will 'rev' more easily, then you will tend to 'rev' more, so how to save on FC

[Gimmegimmes]

Other than Mustafa, any other places to get the tool to remove plugs? Preferably in the North .

 

Bro Vtim, for the copper 2-legged, no issue with a KIA eh?

Hey Genie,

 

Any comments on the NGK Platinum plugs that terrence is selling? How long can it last? It looks cheap at $30 for 4 pieces and if I read the thread correctly, platinum plugs can last about 120K? can this NGK platinum last that long? From the thread the iridium plugs will last only 40K but it cost $50 for 4 .... does not really makes sense to me...I am not talking abt performance but longetivity

[Genie47]

They are the Pt plugs sold in the US. General Purpose (hence GP) Pt tipped plugs. Value for money.

 

Depends on what type of Ir plugs. Big thick tipped ones will last longer. Fine tipped ones shorter. For a grocery getter, I prefer longevity.

[Vtim]

I not familiar with the North ley May be you can check if Causeway Point got DIY shop or not

 

Mustafa is 24hrs shopping lah, can go anytime one, I've been there on lots of time, mostly around 0000hrs to 0100hrs to shop, I even bought a 21" TV and LG Home Theater System around 0130hrs there

 

The 2 legged copper plugs are having a gap size of 1.1mm, same gap size as those Iridium IK16 or 20 if your KIA can use IK16 or 20, then the 2 legged copper can be used

Heh i agree with you, prefer longevity too. Btw, so what is the milege I can use for the Pt plugs? I have already installed in my car at 20K and my milege is 40K now...can it last till 100K? Driving an Aveo sedan 04

[Genie47]

100k it is then. Mine are double Pt. Already 95k.

[Trex101]

Both NGK GP platinum and NGK IX iridium can last a min of 60k. The differences between the 2 are the ground electrode design and material conductibility. The iridium are reputed to give hotter kernel flame thus better for high boost turbo or Nos useage while the platinum are not.

Say.... is there a diff in plug gap for the NGK Iridiums you're sellings compared to the Irriway?

 

My mech looked at it then said.... its for NA car..... then said can use but not so appropriate. Then charged me $40 to install... NNBCCB..... and if I get from them the Irriway 7, its $80 plus $20 install..... lidat how to save???

 

Say your lobang got do scoobies boh? That freelance mech..... how much he charge ah?

[Trex101]

My freelance mech charge $5 to do plug change. The gap size is standard, if your owner manual say 1.1mm then it's 1.1mm unless got Mod, rule of thumb (every 50hp increase you got to increase your heat range by 1 and gap by 0.1mm)

[Dwoon]

Errr... sure or not? $5 to change spark plugs for boxer engine? I wouldn't mind paying $10 since its quite tedious. You might want to check with him since the water container and the air filter box have to come out in the process.

 

Thanks.

[Trex101]

Dunno leh, he always charge $5 for plugs change but normally it's a package thing. Oil change + plugs change

[Clubace]

Do u have gd copper plugs?

twin ground electrode copper plugs, definately better then the single electrode. see pic

 

Its about time to change spark plugs......you got the twin ground electode copper plugs for N16 sunny?

 

 

Sorry for digging up a old thread.

[Genie47]

Get normal ones lah. NA petrol engine doesn't seem to benefit a lot from performance plugs. My personal experience. Unless the plugs are lousy to begin with.

 

I drive my car on dbl Pt until 100k and it still runs great on petrol but on gas, like old man choking on fish bone and wanting to die. I reduce gap, still like that. Change to NGK copper, gas still like old man but petrol still good. Change to Volker coppers and same thing happened except that it felt like choking old man on petrol as well!

 

Changed to NGK Ir fine tip and now both gas and petrol like young man taking evening jog.

 

In conclusion, CNG for my car cannot take copper plugs. Not even NGK coppers. Have to be IR fine tip.

 

Want to test a plug? Send them to me. CNG is really plug torture test.

[Genie47]

On second thought, you can give Vtim's double ground electrode ones a try.

 

It will fire on on ground preferentially until the gap becomes too damn big and it starts to fire on the other one and hence prolonging it's longevity. However, there has been talk about these plugs restricting the flow of gases.

 

Not all cars can use it. Best you experiment if they are cheap enough.

[Clubace]

Yeah..its cheap enough to try it out.
