Police in South Australia urged drivers on Wednesday to step up efforts to protect their cars, as thieves target the catalytic converters that scrub exhaust emissions, amid a surge in prices of precious metals.
The converters, which strip particulate matter from emissions, contain high volumes of the precious metals platinum and palladium, whose prices touched records this year.
After several arrests, they are encouraging owners to mark or engrave the devices with the vehicle identification number, as well as making them harder to remove, for instance by welding in the retaining bolts.
Prices of platinum are up 38% from a year ago at $1,173 an ounce, while palladium is up 43% at $2,758 an ounce.Other measures include parking in locked or well-lit areas, near walls or fences with the car bonnet facing a solid object to discourage access to the converter.
