hey guys, my dad just bought an '04 xf coupe 6 speed. i'm all into the performance parts in my protege 5, but my dad doesn't really like altering the factory parts. i'd like to get him an intake of some sort. what would be the best route to go? i've read the k&n replacement filters are pretty good. what about the dual cone filters with the couple inch piping? sri if i ever saw one (or 2 lol). are they any more functional than the k&n replacements? may also want to buy other parts either performance or not. any suggestions?

oh and what's up with the stupid flip up whatever it is where you rest your arm behind the shifter? everytime i rest my arm there to change gears it always flips up. what can be done to fix this? i heard there was a cupholder replacement???
please give me some tips as i am fairly new to the xf.

thanks,
AJ
