Do I Need New Aluminum Bolt Kit for VCG

Car is a 2006 BMW 325i (production date of July 2005). I purchased a new VCG from AutohausAZ and they also recommended purchasing the aluminum bolt kit. So I went ahead and purchased both. I previously read some threads where some say it's necessary to replace the bolts and some that say it's not. I tried searching but couldn't find any info.



I haven't replaced the VCG yet and was wondering if someone can help shed some light on whether or not the new bolt kit is required for my engine.



Thanks in advance...
