good product, get electric valve

Summit RacingSummit Racing Verified Purchase

All in all I enjoy the product very much. First thing we did was weld the bolts on to the flange so when removing the cap is slightly simpler. The one thing I will be buying soon however is an electric valve for the cutout. Great buy for the price!

Bought this instead of going with a pricier unit. Works just the same. Great value for a manual cutout, could always add the electronic piece to this in the futuer
