Bosch vs ntk? I need to get all 4 02's the Bosch are only $20-30 more per 02 so I don't mind but I've read ntk are better. I'm gonna be wrapping my manifold but their is the extra heat of a top mount

If you want to keep dumping money into burnt up primary O2 sensors go ahead and go with oem bosh ones. Your call. I personally went with ADV O2 sensors from Speedtech. I've gone through headaches of oem ones not lasting long at all.

sorry to bump this, but you put the 2 front back to the cast speedtech manifold, and the 2 rear on the Y downpipe, where there's 2 bank close to each other ?

Question is , those 2 on the downpipe will essentially rear the same thing, is it preferable to cancel 1 to avoid bad reading or both are necessary to match the 2 front ?

scrap the 02 bungs on the manifold I had some plugs laying around that I threw in. Car ate 3 sets of 02 sensors before mhd finally came out with single bank no issues since. drives much nicer, cleaner afr/trims and your not gonna be killing sensors left and right. Put 1 pre cat 02 in the bung of the downpipe. 1 post cat in the same stock location. Confirm which plugs they should connect to i believe it’s bank 1. Select single bank fueling when flashing mhd. Also ntk sucks ass or I just have the worst luck. I’ve stuck with oem bosche

are you using solely MHD?

i'm on a back end map right now from jb4tech and getting my target boost pressure via the JB4.

I was planning to use O2 extension of 90°, worked great in the past.
