GOLF MK3 TDI spark plug

[MBR]

hi. im about to change spark plugs in my golf and im wondering if there is any performance ones? which would be best? thanks

Er, diesels don't have spark plugs mate.

 

[MBR]

the orange spring flashing in the dash board and a mechanic just had a look at it where he said "its a glow plug problem, it needs replaceing"

 

[MBR]

yea, sorry, i thought glow and spark plugs are the same thing, my bad

 

[T9 man]

Never heard of a performance glow plug! :blink:
Hopefully someone might be able to shed some light on this?

Just a minute hold the phone :embarrest: just done a quick surf and look what I found: http://www.suttonautofactors.co.uk/glow-plugs.php

Well I never

thanks

 

[T9 man]

Your welcome

 

[pgarner]

to be honest mate no such thing as performance glow plugs

they are only used when the engine is cold, after that the diesel is combuisting due to the compression


and welcome to the site mate

 

[Yugguy]

No worries. Don't waste your money paying over the odds for glow plugs, they are used to warm a diesel's cylinders for cold starts, they have nothing to do with performance as once the engine starts to get warm they are no longer used. Posh plugs heat quicker so help the engine get warm quicker but don't add power.

 

[T9 man]

So the website is a little bit cheeky using the word "Performance" then PG

 

[pgarner]

not at all, someones bount to buy them and say theyre great

 

[MBR]

do they do anything then apart from heating the engine quicker? eg. reduce emissions or such a thing

 

[Yugguy]

They might reduce emissions indirectly, as the engine warms up quicker, but I doubt it's much difference.

If you want performance change the air intake and exhaust. Can the mk3 be remapped? Even if not a bigger intercooler would give you more power.

 

[pgarner]

on more modern engines they can be used to raise the combustion temp to help clear particle filters but thats it.

 

[MBR]

yea, I think you can remap them

 

[pgarner]

yeah can be.

you should see around 120-130 bhp depending on the engine. dont think the Mk3 got the PD

 

[Yugguy]

Aye, a decent remap and regular servicing is all you need for a diesel really.
