## Customer Reviews

### ⭐⭐⭐⭐⭐ Golden
*by M***T on April 7, 2025*

The size is OD, not ID so keep that in mind when ordering, because of that I could use I for what I needed it for .

### ⭐⭐⭐⭐⭐ Overkill Heat Protection - Looks Amazing!
*by J***N on August 25, 2020*

I used this to heat-wrap a new alternator wire for my 2005 Cadillac CTS-V. Do I need heat protection to 800°F? No, it's somewhat overkill. Does it look awesome in GOLD? Absolutely. Fits easily over my 1/0 AWG wire. (Would not try to go smaller than 3/4 for this gauge) - Had to use 2 of them because the run was so long on an LS6 engine. (Alternator is on bottom.) - A little more expensive than the silver, but I feel it is worth it if not just for the looks, but knowing your cable is extra protected.

### ⭐⭐⭐⭐⭐ Oil cooler lines
*by A***S on April 16, 2022*

The media could not be loaded. I made a mistake based off someone else's review and forgot to account for the fittings at the end of the hoses on my 10an lines. So I cut them and used metal tip ties to wrap my lines since they will sit behind my watercooled alternator. Hope it holds up well.
