i use a regular jack but learned to go further in start lifting a bit, then pull back until it touches the rocker cover. then i lift it with no issues.

it also depends on the mode your in. in sport mode i am mostly interstate and get about 21.

Haven't noticed it on my 15'. but i will be checking it out. thanks

i changed all of them when i bought mine. and sad to say my cabin filter was way worse, looked like it was parked under a tree. nobody seems to remember to take care of these things.
