Spark plug question

[Wolfy3769]

In very basic terms =>

High heat range, i.e., colder plugs are for highly tuned high HP engines

Low heat range, i.e., hotter plugs are for lower HP engines

 

So, if your avatar pic is an indication of your ride, use cold plugs. Which in your case, shd be wrong plug as you shd be looking at IK22 and above.

If it's a Impreza 1.6TS, you used the correct plug.

 

 

so in case my car was IK20.. but if i use IK16... mean i will experience lost of HP?

Nope, spark plugs doesn't create HP. Worst case scenario would be pinging under extreme heavy load or very high rev.

[Trex101]

can this plug be used for most BB car?

 

Denso does come out with a cheaper version(>1/2 cost of iridium tough) call Denso Platinum TT which is design for 100k km usage.

Is this Denso platinum TT in Sgp?

Should be able to get the correct type and heat range for your model and engine.

Search the web for sparkpatk comparison table. Denso web, etc should have.

Do your homework first b4 going down to get it changed. At least you will know if they want to smoke you.

Correction: Sorry wrong information, Denso Platinum TT are designed to last 50k km, not 100k km as stated above.

wat are the main difference between the iridium & platinum other than the price??

There is long life iridium and there are performance iridium but generally the smaller the centre electrode the stronger is the sparks created. Same theory for platinum too.

nope, i'm not driving a scooby, i'm driving a bread and butter vios. that is me remote control car.

 

so, does this mean they have used the wrong plugs for my car?

 

Hi hi bro. I did a search for your ride and your ride shd be using #16 plugs.

As one of the contributers on top provided, Denso's site helps to locate the plugs you shd use. Go to:

 

http://www.globaldenso.com/en/products/aft...arch/index.html

 

Click on "S'pore" --> "Automobile"

 

and a .pdf file will come out. Your ride is listed within. There's two models (03 and 07 models) but both also use #16 plugs.

 

As for whether wrong plugs or not technically yes but it's not disastrous to your ride if it has been properly maintained and should not cause catastropic failure to the engine. Toyota engines are built way sturdier. But ultimately its your ride so if you really feel uncomfortable go back tell them wrong set wanna change or maybe get new set plug in.

so in case my car was IK20.. but if i use IK16... mean i will experience lost of HP?

 

Trex101 is correct. I try to explain why:

 

Your ride uses #20 plugs, i.e., colder plugs to better dissipate heat. This dissipation readies the chamber for the next explosion by the AF mix to produce power to drive the car By using #16 plugs, heat gets retained and this lingering heat when in contact with the next AF mix pre-combusts before plugs provide the ignition to the compressed mix. So with this, precombustion may occur under high load situations. So technically, correct plugs dun really add power as the correct usage of the plugs was what the car-makers intended the output to be but a wrong plug may "rob power" in the sense that the whole 4 stroke cycle (intake, compress, combust, exhaust) is leacking. Hope it was clear enough

Fantastic summary. I also learned

True to the point in a short paragrph

bros,

 

yesterday went to regular mech for reg servicing for my 05 vios, usually using spark plug IK16-xxxx, saw them using IK20-xxx, spark plugs, both are from denso...when asked them, they said as they do not have stock for IK16, they used IK20, assured me the same, in fact more power in sparking, is this true? what is the difference between the two of them?

 

thanks

 

Normal copper spark plug with correct size and gap can do the job and try to stick the heat range recommended in your car booklet. As for Iridium is too luxurious for any < 1.6 car unless you run turbo engine. To me as long there is no problem with autogear box and engine I will be very glad. Last thing check the maintenance manual that need to replace the wear and tear. 2005 car wear and tear dun expect as new as before.

Hi borrowing this thread so as not to waste bandwidth by starting a new one..

 

saw another post by a fellow forummer recently (abt a week ago) that it's qt common to get denso "fake" spark plugs nowadays..

then he went on to post 2 photos, one with a silver tip and another with a gold tip..

the moment i saw that pic, i remembered that the spare plug that i had, had a golden tip..

further postings by the TS confirmed that the gold tipped plug was the real denso plug after writing in to the company.

 

after seeing that thread (which i cant find now), i went to check my plug and to my horror, the tip of my plug seemed to have 'oxidized'

they were unused btw.. pictures as attached:

 

 

zooming in on the tip:

 

 

could the plug be 'fake'?

had some trouble starting my car recently and sent my car for repair..

workshop which is repairing my car was the workshop that installed the spark plugs as shown above..

wana get things right lest i make any false accusations

 

Will appreciate any replies, thank you

Silver colour terminal for IK20 is correct, "copper or bronze colour terminal" are for IK22 and above. so from the picture, silver for your IK20 is a genuine Denso spark plugs.

[Ooosh]

in my opinon....stock copper plugs are good enough as Copper is a better conductor of eletrictiy than Iridium...so if you change spark plugs on every 10k servicing, go for stock ones. one piece only $3+

 

Iridium are for people who drag till 50k before changing plug
