xtx throttle body dimensions
 

Hi guys, currently going the way of making my own dna stage 3 for my 05 xtx due to the high price of the original. I got the idea from another forum member.
The problem I have is i work away from home and wanted to purchase a silicone hose online so its there when I get home so i can work on it. Im buying a hose to go from the filter straight onto the throttle body.
Do any of you guys know what the outside diameter the throttle body is or what inside diameter hose I will need.
Any advice much appreciated.
Thanks

outside diameter the throttle body = 51mm
