Putting in a jet Kit?????

Aight I just registered to this site but have been reading alot of the past threads in here. I just wanted to get some opinions on how hard it is to put in a K & N jet kit. I just got one for x-mas and was wonderin how much it would suck to put in. Also does anyone know of any sweet lookin graphic kits for the 300? If so let me know the websites or post some pics. well that's all for now thanks for all your help.

want a suggestion?
return it to the store & get your money back. buy the ONE jet you might need & carry the other $50.00 to chuck e cheese & throw yourself a party.

if you really want to install it, the tools & technology required are not very high tech. give it a try.

I agree with 3punksdad, just by the jets you need. Don't expect any power gains unless you change the exhaust and do some airbox mods.

Well thanks for your inputs, as for the exhaust and intake i got a pro circuit t-4 system and a k & n filter with outerwear so i got that part taken care of.

Now what about some graphic kits? I have not found many that look really good on a 300 anybody have any pics of some that i could look at?
well thanks for the help

get the n-stlye sticker kit and seat cover combo,i got them last week and it looks real nice..go with a stage 1 jet kit,it cost like 50.00 or get a 132 main jet with a 40-42 pilot jet since you have a k&n

i wouldnt buy any kind of jet kit that is for sure that riped me off on my scrambler with that jet kit junk anyways regular jets work just fine and cost 3-5 dollars where i live.
