New Silicone Plug Leads - do they still need the Plastic Sheathing?

[DaniBoy]

Sorry if this has already been asked, but searches weren’t turning up anything. I just did plugs and wires in my 2010 998 RS. I used BajaRon’s kit. I’m surmising that the replacement wires are silicone, thus I’m questioning the necessity of putting the black flex “elephant trunk” sheathing back on, as silicone, unlike the factory wires, is already excellent for high heat. I appreciate your thoughts and comments on this.

The only reason I see to use it is if the wires are touching or laying against something that might cause wear due to vibration. I think I would use it just for that reason. A little peace of mind if nothing else.

..... the reason BRP put it there is because they know their wires are " garbage " .....Mike

with both comments also. I would put the black flex “elephant trunk” sheathing back on. I don't think you want to go back in there before it's time to change the plugs again.

Good advise. Extra protection never hurts. Is it necessary? I've had customers do it both ways without issue. But I would still recommend putting the outer shielding on. Can't hurt and it's not hard to do. Looks a bit ugly. But you can't see the wires anyway.

Good question!

You already have the sheathing, so just go ahead use it. It won't hurt anything and it may even help the wear/rubbing or keeping the wires clean.

I would definitely install the BRP Sheathing.
Better protection from general wear and tear.
Should be the last time you have to replace your plug wires

Sounds like we've reached a consensus other than the negative Nancy's on here. I agree with the above comments.
