One thing to note, prior to having my K&N Intake installed I could not make it up this hill as I would bog down!
Trying a sandy hill
Sand and hill are not the Mk's best strengths it absolutely sucks all the power away, since my intake it is better but any type of deep sand and an incline will leave you bogged out. I had to go almost full throttle the entire time and while it looks like I went up easily the engine was working very hard.
Here is a video showing how I got bogged down. Yes ESP was off and I was using FDII mode.
Didn't matter what I did, not enough torque to get going anywhere meaningful. This sand was a bit deeper on this line.
Another steep hill, made possible to crawl up due to my intake:
Bottom line, K&N intake helps offroad, although does create some more noise.
