RCD Performance 6.7 Powerstroke Thumper 33% 10.3MM CP4.2
RCD CP4 Common Rail Pumps offer the highest displacement in the industry.
They start as all new genuine Bosch parts that are modified with a industry leading cam design, tested and then shipped to your door. We will not sacrifice quality for a lower price.
This 10.3MM high pressure fuel pump displaces 48% more fuel than the CP4 pump on the 11-14 6.7 Powerstroke and 33% more fuel on the 15-17's!
We have dyno tested well over 850RWHP with this pump and turbo mods.
