Silicone grease/rubber bits

Hi, I have horrible intake leaks on my R1100RS so it idles high/backfires and gets worse as it gets hotter. It looks like both inlet manifolds/rubbers/whatever you want to call them are knackered as when I spray GT85 around them the bike bogs down, plus they look a bit cracked/twisted.

My plan is to get some replacements but I also read you should use silicone grease on rubber parts like this? Will this help them seal, or make them last longer? What does it actually do? Just working out whether to order a tube - quite pricey stuff.

Wintergreen oil may well help in the short term.

Be careful using it.
