Note: Requires gap to be set prior to installation
Check with your mechanic. There's a few more deals out there on Supercheap right now. I think they are getting new stock.

Not sure of quality but may last up to 30000km before replacement.

Full copper core electrode with high nickel alloy shell provides great performance in all conditions
Designed to deliver quick starting, smooth acceleration and good fuel economy
Copper-glass seal is 100% leak proof, assuring full voltage is delivered to spark gap
Insulator ribs increase surface length, reducing the chance of spark leakage and misfire
Note: Requires gap to be set prior to installation

  NGK or Denso all the way. More often than not, around the same price. Picked Denso for less than $6 from not a Supercheap store recently.

    Never seen ngk for $8. Usually $12-15 but agree. Ngk is better. Platinum coating so lasts 60000-100000)km

    Sorry can't say. Haven't seen this brand before either. There was a deal on basco spark plugs for $6 but my supercheap ran out of stock.

  Or buy it here for $2

    But there's only 1 item in stock so it's extremely insufficient stock. Not worth it as the $2 spark plug + $10.05 delivery fee is way more than $7.29 just for the 1 spark plug that's in stock. At least SCA has way more than only 1 item in stock. It's probably why nobody's bought it.

  don't cheap out on unknown brands for something that's a vital engine component

    Autolite is not an unknown brand. It's a big American brand that's actually the official spark plug supplier for NASCAR in the USA.

      i don't follow nascar but i obviously these "official suppliers" pay for the privilege. they're not exactly chosen by merit.

  Somehow I bought Bosch plugs $6 each by the link and only then realised the OZB deal was for Autolite
