Title: Spark Plugs...
Post by: Bixy1 on 15 February 2010, 23:43:35

Evening all!
This is probably a really silly question but which is best, Vauxhall spark plugs or spurious, ie, NGK, Bosch etc, etc.

I alway use Vauxhall ones.
I've tried and fitted the more expensive ones and had no improvement (not that you would expect any) and in some cases poorer running (i.e. Bosch Super 4's)

What you have to consider is that
 the Omega engines are pretty efficent so dont have massive cylinder temps unlike say a Turbo car
 and the engine management setup really extends the plug life through tight control of timing and mixture

If you check a set of 40K plugs and measure the elctrode gap, it will be pretty much the same as the day it was fitted!

IMHO You can't sucessfully gap a set of OE plugs due to their design!   :-?  :-?  :-?

but I do agree with using Vauxhall plugs ... afterall they're only £15 a set  ;)  ;)  :y

Interesting!  Ok Vx it is then.  Thanks lads. A mechanic once told me plugs were important and as a general rule
Champions go in British Leyland, NGK's anything Japanese, Bosch anything German, and AC Delco in Vauxhall.
(This was a long while ago!)
As an aside, my GM engined diesel Astra had NGK heater plugs in and when I changed them for Vx ones starting was much improved!  :o

Probably because the old ones were goosed!

More often than not, the Vx OE glow plugs are Beru ones

Yes you're right about them being Beru, but the old ones were new! Somebody had changed them just before I bought the car.  :o

I'm impressed!  :o  Main Dealer parts cheaper than motor factors. 4 plugs, part no 9195109 GM branded, £14.92.  :y
Goody!
Not so good, bottom of rubber plug lead breaking off on 1 & 2. That was fun digging the bits out!  :(
New plug leads then.........

No choice but to change the plug leads now, a slight misfire has started.  :( Can anybody recomend a good place to buy some?  Thanks all.  :-?
