All replacement parts used are genuine Isuzu parts or are made to original equipment manufacturer (OEM) standards. This means they are manufactured to the same high standards as the parts we use on our manufacturing line and are subjected to the same performance, quality and durability tests. Beware of ‘aftermarket parts’ that claim to be genuine Isuzu parts. They are not genuine and do not meet the strict quality and standards specification of Isuzu parts. We recommend only using genuine Isuzu parts, because the quality of a single component, no matter how small, has an impact on the overall performance of your vehicle. Using non-genuine parts may affect the performance of your engine or your vehicle in general.
