dont get a k and n, i work construction so i work in dirt and mud and dust. it gets filthy very quick and its loud but i havent heard it since the high flow cats got thrown in. its gets to dirty to quick and it is also very open to water as i found out mashin through the woods...also one ended up ruining my dads chevy, it burnt out the Mass air flow sensor and that somehow, according to the mechanic, ended up frying the cats. the oil from the filter was the killer. i guess it got all over that, fried it, and was no help to the throttle body. this happened over about 100k miles tho so its not going to be quick. its an 03 with 140k i put it on at 30k took it off at 130k. he also works construction so he was around dust, dirt, he cleaned it somewhat often. but never went wheeling. i did once and blew the tranny the first time(out of three, it was his first chevy since his impala in the 70s, first chevy truck ever. HATES it)... so good luck, sorry i couldnt tell you what to get, but what not to get is also good help as well
