does anybody know how this thing works?

I got a bunch of them with my manifold for securing the wrap but i have no idea how to handle it
(I don't even know what this thing is called to google it)





thanks

I've always received metal zip ties. GL with that doo hickey.

I recommend not wrapping. It causes the metal to corrode faster and can be a big sponge for flammable liquids. I've used it before and to me it's not worth the tiny increase in performance. If you are trying to protect other things from the heat, use a metal shield/foil instead. Oh, and you could get them coated as well to hold in the heat.

when i do it, i just use safety wire. works better.

as more and more people keep telling me not to wrap the manifold I'll let it like it is and will try to modify and mount the oem heat shields instead

I wrapped my manifold for all of 5 minutes on my last car until it came loose on the FOERST drive and I noticed it was bright glowing red underneath. I guess thats by design?
