We might carry a small selection of Full Tilt Performance manifolds here at Raney's Truck Parts, but we can guarantee they represent some of the best aftermarket replacements for Detroit Diesel or Cummins engines. These manifolds are directly compatible with your existing setup, and cool your engine more effectively than their OEM counterparts. This, combined with their increased airflow, means reduced fuel consumption, noticeably decreased turbo lag, and improved horsepower across the board! Don't just take our word for it, though: give us a call or shop online today and see just how excited we are to be an authorized Full Tilt Performance dealer!
