I wanna replace my o2s because they're still the oem ones and are 18 years old. I'm getting horrible gas mileage and this is the only thing I haven't replaced yet. I wanted to get the oem denso ones but the family mercedes just got a huge repair bill so I need to cheap out on the o2s.
Would these fit? I know i have to splice the old wires and reuse the old harness, just wanna make sure this fits, thanks!

Do you have a SC300/400? You can check part numbers at this website for both OEM and OE universal ones.
