Best spark plugs for a Z18XER?

[Baz07]

Can anyone tell me what the best spark plugs for the Z18XER engine are.

Best for performance and reliability.

Cheers

Vauxhall's "own" brand.

Not only cheap as chips but will the correct ones.

Have a look at Denso Iridium on "carsparkplugs.com" cheapest place around for plugs.

Our car is a 55 reg Facelift Club Hatch with the Z18XE (pre facelift)...

I usually fill up with 95RON unleaded supermarket fuels mainly from Morrison's & Sainsbury's then on rare occasions Tesco, Asda, our Co-op's Texaco, even rarer a local Shell garage....

These are the Bosch Plugs fitted by GM from new....just removed & replaced after 4years & 39Kmiles...

The plugs look in excellent condition.........and are as removed....





I used NGK BKR5EQUPA 4 electrode plugsas I work part time at a local motor factors & we stock NGK plugs (Details of suitable plugs on the NGK web site).....

Hope they perform as well as the previous ones....
