I just bought a HDJ81 a few weeks ago and it came with an intercooler installed. I recently had someone that knows about these engines recommend taking it off to return the intake system to stock. Does anyone with more knowledge then me have an option on this topic? The way I see it is that the intercooler cools intake air temperature. On the flip side I've read that an intercooler can decrease power (by way of increasing the distance the air has to travel to reach the engine). The other question is: does air fuel ratio need to be adjusted when an intercooler is added if so was this done when mine was added? Let me know!
