ok so I kinda feel stupid but what exactly is ISR? I know it deals with air in take from what I see but can any one explain it to me and post some pics so I can fully understand it and how can I do it to get more performance out of my pick up? thanks in advance

 

the isr mod pretty much allows air a more straight path into the engine
these are the intake silencer's they slow the air path down to cut down noise and rob power

this is what a isr mod looks like a much simpler way to allow air into the engine which means a little boost in power

 

thank you this is exactly what I was asking for!!!

so do you feel a difference in power and gas mileage and would you recommend it for me to do

 

its a pretty simple mod and any little thing that can help the 3.slow some is worth it

 

is yours home made or bought ? what did you use?

 

pics showed where borrowed from this writeup

Does anyone sell a kit with all the parts/prebent tube etc.?

 

Yeah, head over to Kragen, I believe they have a whole kit on it.

Here is a link to mine. I used plastic tubes and an elbow.

I am wondering the same exact thing. I googled "Kragen" and only came up with Parts America (which I am guessing is a supplier). From that website I searched and only found the K&N FIPK.

Edit: I did some more scrounging around YotaTech and found this:

Hope this helps! That is most likely the route I am going to take.
