so im running a k20z1 swap with a hasport engine harness and was wondering which primary o2 sensor did i need? i have two different part #s here for the denso oe replacement sensors... one is part#234-9005 which is for the 02-04 type s model and the second part# is 234-9064 for the 05-06 model.. does it make a difference in which one to use? or could i use either one??
