Question on spark plug thread

[Venco25]

I am keen to get a set of Colourtune & I have been asked to confirm my spark plug size. There is a note that says :

 

"Note : Both 14mm/12mm and 14mm/10mm Spark Plug Tread Adaptor Kits are available as optional items. Pl email for price and stock status."

 

How do I know what size I need? BTW, the product description is a "14mm Colourtune kit" Thanks for any advice!

[Kyojin]

get the 14mm from bro YEOBH

 

it's very easy to use, but not 100% accurate. you must still have gut feel.

The product comes in three sizes namely - 14 , 12 & 10mm. The size refers to the spark plug size.For some mechanics or DIY tuners, they will purchase the std 14mm and buy adaptors ( 12mm & 10mm) so that they can tune wide range of vehicles, motorcycles, small engine, ATV and even small marine engines.

Thanks for your help, I am glade you have a great time tuning yr ride.

[Venco25]

I see. So 14mm is the size to get?

[Venco25]

Thanks, Kyojin!

[Yeobh]

Kyojin,recomendation on thread size should be right on the spot - I believe his ride is similar to yours.

[Kyojin]

yes, 14mm is the correct size. most car engines take 14mm.

Tks for the reply. And what is the tuning plug u guys r toking abt? I wanted to buy Denso Iridium but I duno what size also. Duno if the plug cable can fit anot also.

[Kyojin]

1. thread size: is the diameter of the spark plug thread (thickness). what bro showed here is the reach (depth).

 

2. there are many opposing views on Iridium/Platinum spark plugs. But I changed from Iridiums to copper and there's no loss of power. In fact for less than $2 each, the copper spark plugs do the same job. and you can get 7-8 sets of copper plugs for the price one set of Iridium. meaning: you can get fresh set of plugs every time you change oil! fresh spark plugs give you more performance gains.

[Jeronleow]

Tks bro. Then can explain what is the tuning plugs for? How does it works?

[Kyojin]

to tune the correct air/fuel mixture for carburetors. mainly for those who have a Weber carb.

So how's your ride after our "early" DIY session?

 

Hope all your problems are resolved!
