    84170 - Crower Valve Springs is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from DOHC camshafts, 3/4 race I purchased these for my Ford Focus engine in May and had them installed in June. They appear to work well, and would probably would provide more HP if I increased the compression ratio over the stock 10:1. Overall I am satisfied with the product.
