As the Jeep pulled onto the Dynojet, our anticipation grew. Would the increased flow equate to more power, or would our pipe fall flat? We removed the stock intercooler pipe from the JL and installed our free-flowing cast-aluminum replacement. We strapped down the Jeep and fired it up.

Last time we saw our 2018+ JL performance intercooler pipe, we were finishing our flow testing. The flow bench showed that our 3D printed prototype flowed 27% more air than the stock pipe. We expected our cast aluminum pipe to flow a little better, but when we tested our production sample, we were surprised by just how much better. Thanks to the smoother interior of the cast aluminum, our production sample flowed over 36% better than the stock pipe. But, as we saw with our 2018+ JL intake, more flow doesn't always translate to more power.

To see if all the extra flow would translate to more power, we needed to
