HPX for 7.3 Ford
Quality of part was excellent. Installation was a breeze. Limited disassembly required to install the HPX. I didn't see significant difference in idle quality. Overall, I do believe this will benefit the performance of the engine. Would recommend to improve equality of engine ouling.

Small but significant
Small subtle changes like this crossover and compressor wheel and return fuel line and bellowed up pipes all add up to a more efficient vehicle operation. Increased power and better fuel mileage. Can’t complain about making things better! All good!
