Review on Moroso SPARK SLEEVES TEMPERATURE BLACK by Matthew Blustein

I have a Jeep JK (3.8L V6) with aftermarket headers. The headers generate more heat under the hood, so trunk protection is important. I've used a cheap Auto Zone tape heat shield on my wires for years. When it came time to replace my wires I decided to purchase these jacks as an upgrade. The temperature performance of 71994 surpasses cheap foil. I had just blown one and the wire melted right in the trunk and the top of the trunk was mostly dust. Not even a year has passed. I had the slide there for 2 years. The Moroso guarantee is only 90 days. I know there's nothing wrong with only burning 1, but it shouldn't have burned at all and Moroso should have at least cared that it could be a defective pair as the other one from the same pack is rock hard.
