My Dakota is a 5.2l and i put an air cleaner on it. I am going to put a little filter for my breather since the aftermarket air cleaner doesn't come with a hose and attachment for the breather (like always). I was wondering if anyone knew what the size of the hole on the stock breather is? They sell them on Summit for 2" and 3". Thanks.

 

I don't know the size but why not go pop the hood and use a measuring tape and check?

Other then that the next best way is to go to www.napaonline.com and check the specs.
