🔥 Design Engineering 010419 Heat Sheath 1" I.D. x 3ft Aluminized Sleeving: The Ultimate Solution for High-Temperature Protection Review

Based on my experience, this product didn't offer any significant improvement to the performance of my car. The only good thing about it is that it is easy to install. However, it didn't do much to protect my car from the heat. An overall waste of money.

I used a 3/4" x 3 ft sheath. It was used around a 0 AWG (8.25mm) starter cable that was installed very close to the catalytic converter. Magnet wire starters were double shielded so I folded the 3/4" grommet and used stainless steel zip ties to keep the folded grommet around the 0 AWG wire. + Looks like quality materials. + Good stitching.

Heavy duty engines generate excessive heat in the engine compartment, some fuel lines and electrical wiring are easily damaged due to excessive heat, especially some electrical wiring near the manifolds. Heat can reduce proper electrical current, using this aluminized sleeve I was able to reduce the heat a bit and keep my electrical wires carrying the proper current without sacrificing performance.
