    31183 is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Low ohms Really great wire set and what’s really nice is the included wire crimper to make the wires, super easy, terminals are crimped on tight like they where welded on. MSD claims only 50 ohms of resistance and my set measured 48. I have aluminum heads with tall valve covers and standard pre made to fit wires don’t exactly fit right, 3 wires are usually short and these you just cut for a perfect fit. Another great product from MSD.

    Rated 5 out of 5 by from Excellent plug wire set. These wire sets are great for high compression engines. Look forward to year's of service.

    what is the size of the spark plug boot? I'm wanting to get spark plug boot sleeves. Jegs has them in 7/8" or Taylor has them in a 1".

    Asked by: Ballan
    These boots are universal and will fit any plug wire of 8.5mm in diameter.
