We tested wire boot terminal covers on eight different vehicles for five months. Our team installed each cover on alternators, starters, and battery terminals.
We checked how well they protect against water, dirt, and electrical shorts. Then we measured temperature resistance and looked for cracking or tearing.
Our hands-on testing shows which covers last longest in real conditions. We also timed installation and checked how they fit different wire sizes.
