At BPRATV we stock the same parts from different manufacturers so that when back orders occur we have an alternate part to send that is the same quality. This would be the ONLY reason your order might be slightly different when it arrives. 99% of problems can be easily solved without returning the entire order. Once items have been modified, installed, or used in any way they are not eligible for return. This product is NOT DIY.
Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person assembling and tuning the engine to make sure all the parts are correct and work properly. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most. Please work with us and we will ALWAYS work with you.
