gates powergrip to be precise (which is what i use as my non genuine part)
oe is exactly the same as the gates power grip kit, the only difference is the renault kit has a renault diamond on it, they both say gates powergrip on them!
same with the aux belt kit, its made by "company x" (i'm not saying who, don't want other traders getting any info!) and the "non genuine" ones i use are infact genuine just they've had the renault numbers ground off the back of them!
