VZ SS spark plugs

[lewi79]

hi everybody,

I need to replace my spark plugs on my VZ SS commodore. It's first time the plugs have been changed.
Can anyone recommend some spark plug types for this model?

Cheers

bosch platinum fusions little expensive but worth the money

Get some Bosch Premium Iridiums (they are on Ebay at around $120 a set of 8 ) There a special heat range for 2005 & later LS-1s & LS-2s (5.7 & 6.0litres) Go to Bosch website to get the exact iridium part number. They will last for at least 100,000klm. Be prepared to skin your knuckles changing them , unless youre a Pigmy!!!!!!

I just replaced mine in my VZ 6 litre and bought genuine Holden iridium plugs, tried the other brands and wasnt happy, runs as sweet as but they are expensive $230.00 a set

umm holden iridium plugs are bosch

Genuine Holden parts aren't always the best option either because most of the parts they use from the factory are designed to be cheapest possible without substituting quality to an extent. Aftermarket makers on the other-hand try to make the products they design the best they can be and the funny thing is they can sometimes be cheaper as we all know how much Holden mark up their own parts..

if its modified get ones for a ecotech/304, they are a colder range spark plug and prevents pre detonation, i run them on my wh cause the heads have been shaved and thinner head gaskets = more compression, and my blown vy ute ran them too,
to find out more search it up on ls1, also the american version of this is tr6 or 5 that they all use
