which upstream o2's for installing Speed Engineering LT headers
I will be installing Speed Engineering 1 3/4" LT headers on my 98 trans am in a few weeks. So I figured instead of spending money on o2 extensions I figured I would just install brand new upstream sensors. Only brands im sticking with are Denso or Ac delco. Which of the 2 have you guys had luck with? Also for the corvette o2's those would be the downstream corvette o2 sensors I would be using correct?
I can't remember but I'm pretty sure it was corvette 02's but I can't remember front or rear or what year. I think it was c5 rears, but someone will have to chime in and clear that up that has a better memory than I do.
