I wanted to replace my front o2s and i ordered part 234-4025 and 234-4087 and according to Denso, they can both be upstream(front o2s) left and right. My mechanic says the wires are to short(yes i have headers with extensions). Is it possible i need like 3ft extensions instead of 2ft? Has anyone replaced their front o2s with denso and how long were your extensions?


Thanks

Should have spent the extra little bit of money and got the Corvette o2's so you can ditch the extensions, but it's late for that. Does your mechanic know what he's doing? 2ft should be plenty.

i just looked at the denso sensor that i use at work for our fleet repair

its nice being a fleet manager

and we use 234-4018 in all our LSx motors as front O2 sensors

especially since i get them for around $22.00 each from supplier
