Hey guys Just a question I been put onto a website in the USA that are a cheap parts supplier, I can get 6 Bosch (4504) HGR9DQI PLATINUM IR FUSION Spark Plugs delivered for AU$54.05 compared to Supercheaps $129 So my question is are they the exact same plug? as I am ordering from a catalog for a 2004 Impala 3.8 (L36) which is the same engine as our Ecotec V6
if their the same bosch part number as holden recommend over here i dont see why they wouldnt fit?, Most of the stuff you buy comes from china anyways, so i cant see how the US will be any different
I have tried Bosch's site to try and find the product number however they only have listed Platinum and Super 4, just not the IR-Fusions.
