I was about to order the grey ford CPS for like 25 bucks but after doing some research I found that the are not the best one. I then read that International made a black one that started with part number #182??????? but that doesn't seem to be available anymore. So i found this black CPS on puredieselpower.com but it is $49. Is this a good CPS is anyone using it and does it really cause your truck to run as good as they say??
