Use a bit of silicone paste as lube on the install to protect the seal from tearing when going in and it should be fine.

I guess what I'm saying is I wouldn't preemptively change a brand new disa seal just because I plan to remove it in the future and it might fail then. I personally would try it and see how it holds up, and then if needed use the viton oring since you have it already.
Yeah my issue is i noticed It was noisey last spring, and the last few week under 28F I'd get a pending code of P0174 on my ultra gauge, and the other day it was 56 out so I thought I'd be nice and open up the throttle abit to blow some carbon out. Ever since at red lights etc it has a slight shutter/hesitant but normal rpms of 650-760 as I normally see it monitor at. But I'll get the pending code again and then takes a day or 2 but will pull the P0174/71 codes. So wanna swap this to rule it out if anything at least that anxiety of the Disa grenading my motor will be gone, jus will be a pain with how cold it is and no garage to tear into the lower boot ugh...
