long term silicone properties question.....
I have a 3" silicone intake. When i put it all together the connections like the T.B.-->90 elbow, 3"silicone to MAF, 90 elbows to HVRS and so on were SUPER tight to get the silicone pipe on there.
It was so tight that it could only be done with all parts off the car and a bit of dish soap to help.
so my question is, after about 1.5-2 years on there, does the silicone start to forum/mold to the part? what I am getting at is if I take the silicone off, will it still be so hard to get back on..or has the silicone moulded/formed to the part?
Random pics of the silicone in question...

Re: Lubricate with silicone grease prior to installation so you can easily remove later.
I was under the impression that silicone anywhere near the intake was a HUGE no no. Bad for the O2 sensors.

You put a thin layer of silcone grease where the female slicone hose end slips over another part..
nozzle, e.g., MAF. You don't use massive amounts of the grease such that it would be sucked through the intake system and damage O2 sensors or anything else downstream.

does not even a super small amount of Silicone in a intakes foul O2's?
not something I will be doing, nor do I recommend anyone else does it.
I do value your opinion, however, it is just bad advice.

especially when there's SO many lubricating alternatives that last as long and have even greater...
lubricating qualities and temperature rating extremes and are DRAMATICALLY cheaper and easier to source. Virtually any moly-based synthetic axle or CV grease jumps immediately into mind. No sensor issues whatever and are specifically compatible with rubber or silicone or siliconized rubber boots while simultaneously costing the same or less "per pound" than di-electric or silicone grease "per ounce." And there's a LOT more uses for such a grease in the average mechanics toolbox than the far more specialized and "limited use" silicone product. Tho admittedly having both is to be preferred over only one.
