Spark plug heat range

[Dwoon]

errr... yah.... I know this.

 

Just that I don't know what gap is the BKR8EIX that Terence has brought in.

 

If its not stated, what is the default? Any idea?

 

Thanks

Actually, the -11 cannot be trusted.

 

I've gotten -11 spark plugs and their gaps vary. Before installing, it is good practice to gap them.

[Dwoon]

But my mech doesn't do that leh..... they just use them straight from the boxes.

 

BTW, can these Iridium plugs be manually gapped? I don't want to "kay khiang" and end up causing more problems instead.

Fine tip Ir plugs can gap but you risk damaging the fine tip. Only fine tip got this danger.

[Dwoon]

Isn't the BKR-EIX series fine tip Ir plugs?

ic, anyway i'm sticking with coppers

damn plats rusted before i'm done with them

i used the two prong earth sparkies (box branded Toyota) from mom & pop spare parts stores at Sin ming........very good and cheap fer my previous Mazzie 323. I think is oso copper ones.

The plug i bring in are BKR8EIX, default gap are 0.8mm. Yes iridium can be gap but need special care and technique when gapping.

 

Proper Gapping

 

In most cases the factory set gap should conform to your vehicle specifications. However if it is necessary to widen the gap, do so with a tool that only pulls back on the ground electrode without touching the center electrode or the porcelain. To close the gap on a plug, gently tap the plug, electrode first on a hard surface.

Wah... siao liao.... is it the same gap size as the Iriway 8 which was what I wanted? Think my recommended gap size is 1.1mm leh....

 

Thanks.

Yes, BKR8EIX is the same as Iriway 8. You can gap up or down if you like, i can also help you if you want.

[Dwoon]

Ok, ok.... false alarm. Think its recommended that the gap be smaller for higher boost.

Glad you found that out. I was wondering why you needed 1.1mm gap. With such a high charge mix, it takes a really little spark to go fwooomph!

[Dwoon]

Errr... never realised that I've been on 0.8mm gap. When I did a search for the stock plugs for my ride.... it shows 1.1mm. Then somemore, I'm using the BRK7EIX-11 which I got from Terence. So now dunno which is the correct gap..... only that the workshops I go to recommend to use the Iriways which I was on previously.

 

So suddenly "kan cheong".... because I ordered from Terence... and also going to pickup the NGK racing plugs R7119-8. Thought I ended up with so many sets which I cannot use.

 

Looks like can use either gaps leh.... but dunno which is the better. Maybe when I put them in, hope I can feel more power.

get the gapping tool la, then experiment yourself.

i noticed the smaller gap i go (0.9mm), the more torque at low end, but a lost of high end HP

then i try 1.2mm, idling not steady, but high end seems slightly more lifely.

so my plugs r now at 1.0mm

by the time they are due for a change, it should still be within my car manual recommendation of 1.1mm.

j/k

 

that time i remember asking if u have the 16heat range, and u mention have.

Wah lau eh..... experiment myself???

 

It'll be a costly affair man..... $40 labour each time to take out and change the plugs.... plus a changing time of about 1 hour (provided I don't have to wait my turn at workshop).

 

Errr.... I'll give it a miss and take your feedback as indicative. Going from 1.1 to 0.8mm, I should hopefully get better low end if you're correct.
