    402020 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from great quality I bought these 2 weeks ago, i installed them and they appear and feel pretty stout my only qualm is i wish the shorter wires were about a inch longer due to igave exhaust manifolds.

    Rated 5 out of 5 by from Good stuff i bought theses wires a few months ago after adding a big cam to my small block, it gets pretty hot under the hood now more than it use to and these wires have held up fine and like always they came in an awesome amount of time never dissapointed with jegs
