anyone know where you can get a cold air intake for a 1991 ford f150 with a 300 inline

 

Try K&N, they have alot of stuff.

 

were are you located from?

 

Orielly's has all the stuff to do it yourself for around $50.

 

all i did for my cai for my 300 was go to an exhaust shop get them to weld up three pipes (two coming from you tb and going into one 3" for the air filter) and then get two rubber sleeves or whatever you wanna call them and stick one end of each on a tb and the other on your cai then get a filter to fit your piping, then just make some kind of braket to hold it cause it will be a bit heavy all steel. looks look once its all painted up and everything

 

Wrap it in header wrap too. Metal will get hot and after the engine heats up your intake pipe will be baking all the air in there!

 

you can paint it all kindsa pretty colors to boot!

 

Or rugged, hard, manly colors, if that's your aiming point haha

 

MAP engines (yours) adjust fuel trim base on barometric pressure, not actual air flow. So your set up will not compensate for too much more flow than your factory CIA set up (yes that is a CAI you have now) provides now. A K&N drop in is more air, but not too much.
