While the K&N and similer intake kits are valid upgrades for alot of vehicles.. Not all of them need it. I have seen many trucks like mine with the K&N cold air intake..why bother wasting money and swapping them out? Just remove the top lid off the stock airbox/intake and either replace the filter more often, or get a washable one. Dont tell me its unsafe.. The K&Ns are just as exposed...
