does anyone know the size of the inlet tubes on a 1st gen intercooler? i am going to put 2nd gen tubes on it and havent had a change to see if theyre the same diameter yet.

i know my 2nd gen intake tubes are 3" and i want to say that the intercoolers for the 1st gens are 2.5"s. anyone know?

or even better has anyone ever put a 2nd gen intake horn on a first gen with the 1st gen intercooler? and were there any major problems and did the factory intercooler boots from a 2nd gen work?

 

first gen tubes are 2.5" that's about all I know.

my power stroke intercooler just showed up so now I gotta find 2.5 - 3" boots.. whee

 

you'll need 2.5-to-3.25.

 

thats what i was looking for. do you by chance know if they both need to be straight or if i need ones that are like a 45 degree angle like the stock ones?

 

i put a 2nd gen intake horn and post cooler tube all i really needed was a 2 1/2 -3" 45 elbow at the intercooler . found mine at siliconeintakes.com pretty helpfull site when doing stuff like this.

 

well my powerstroke i/c is 3 1/4" and i bought my 2 1/2"-3 1/4" tubes from turbohoses.com

oh and budgreen if your using stock tubing youll have to lengthen the tubing.turbo side 1 3/8 intake manifold side like 1 7/8 cant remember exactly how much but somewhere in there when using the turbohoses adapters
