AC PERFORMANCE Black 1 ID Silicone Coated Fiberglass Heat Shielded Fire Sleeve for Hose Lines & Electrical Wiring, 1 inch ID, 3 Feet (25 mm ID)

No dislike here, this wire sleeve is great for the needed fire and heat protection. I think this was a great buy for the cost!

Tested on spark plug wires and does its job

LM7 5.3L with Long tube headers. I had to modify my oil dipstick (well re-manufacture one) out of 6AN hose and the upper and lower portions of the OEM dipstick. If you have headers there isnt a good way to install the stock dipstick unless you bend the heck out of it and risk snapping the bottom off.

Good stuff. Bought it to protect 1/4 nylon vacuum lines on a turbo build. One line fits with ease. Two lines can fit with some persuasion.

Great

High quality product. Does its job and does it well. Great buy!

I had to stretch it out to make it fit a ½ hose. Seems to be the case with all insulation like this though.

worhs well

Bought this for speaker wire protection. I wanted to run speaker wire across my fireplace inconspicuously. Had been across front of fire screen. Now it runs inside the fireplace close to backside of fire screen. As it is black it cannot be seen inside. This saved me from having to drill holes in walls or floors to run wires. Admittedly an unusual use but works great and no damage to wires.

Bought this to use on turbo coolant lines. So far no issues at all. Doesnt melt and seems to protect the rubber hoses really well.
