Looking for recommendations on o2 sensor spacers, I’m running kooks catless headers. I’m fullbolt on e85 so I need to get them out of the exhaust stream and I’d like to get ones that make CEL go away.

Most of the O2 spacers I've seen are modified spark plug adapters. You can do a Google/ YouTube search for tons of how toos.
They can infact work to turn off the CEL but be advised that if they are found you will fail any emissions inspection.

I bought mine from amazon. They work perfect. No CEL and all IM monitors show all ready for inspection

Will O2 spacers work for downstream sensors? That’s what’s giving me the cel

I don't see why not. It's a small investment. Try it out.
