where should i run my primary o2 sensor? in the HF mani?...or in the o2 housing for my DSM turbo, or should i just plug both of them up and put a bung in the DP near the cat?.

also...does anyone know of what i can use to plug up the hole in the mani, and o2 housing, or should i just weld them shut..haha

thanks a lot!!!

 

just get some bolts and grind them down , wrench them in and your done.......then get an o2 bung and weld it to your dp , screw your o2 sensor in and your done with that too.
