Need Advice on E450 Engine Mod
I was reading up on a K&N website about a cold air intake system for my E450 v10 Class C motor home. They said "You could get 17.5 horsepower gain & 22 ft lbs of torque & a small increase of gas mill...

There is no avenue I can see for the KN to increase gas mileage on a closed loop system. It probably increases power slightly at high RPM. I prefer the stock filter for dust removal efficiency.
There is a chip maker, can't remember who, that published some data showing the V10 remains in closed loop operation even at full throttle. Most car engines go to open loop under full throttle and run 12 or 13 to 1 air fuel ratio. This allows more timing advance and more torque. The chip changes parameters to open loop richer mixture at full throttle with more torque and power.
For me, the stock engine has sufficient power and I like the safety of factory tuning. My driving enjoyment is not limited by the power but the handling of the class C. This is my priority for upgrading-suspension components.
