[size=12]Just wondering what sort of spark plugs are most popular for a mv6?
Not sure whats in it at the mo.
Due to fit a set of 10mm fuelcat ht leads.
I did have a set of iridiums in my old v6 sri vectra, but heard they're not the best for an omeag.
Is this right?
Or are there better ones out there??[/size]

Standard GM ones are adequate (twin or quad electrode depending on model year) and good value IMO. Not had the slightest grumble out of mine, even on LPG.

I have had the GM quad plugs in mine now for the last few years. Like you, I havev't had a peep out of thecar .... even though they are the 'wrong' plugs.

Not a fan of the quads myself, rather fit the twins, and change them a bit more often

[size=14]Cheers lads...... looks like there's no benefit in buying iridiums.
Looks like standard for me....  [/size]

been using quad NGKs (not iridium).. satisfied with them..

A spark plug either ignites the mixture or it doesn't. As long as it does that reliably a more expensive plug can only have a longer life. In a very highly tuned engine you might find yourself needing iridium plugs to get a reasonable life but it's a waste of money on an Omega, IMHO.

VX plugs are only a couple of quid each on TC and, being multiple electrode types, they have very long life.

Well, the 4 electrode GM plugs for the later V6s are basically rebadged Bosch Super 4's. They are a good bit cheaper too.
