1998 Oxygen sensors

[QFourFive]

On infinitipartsusa.com they do not have the rear oxygen sensors for sale for the 1998 q45. I was just wondering which brand to buy?

I've read some posts and hear that NTK is good, but they're in the cheapy range on RockAuto.com so it makes me a litlle weary to buy them. Somebody please confirm which ones I need to get.

NTK and NGK O2 sensors are made by the same company and are OEM quality. For spark plugs and O2 sensors, I go to NGK.com a.k.a. "sparkplugs.com." However, you can get a better deal sometimes from Amazon. Right now, the NGK/NTK 24545 Rear O2 Sensor at Amazon.com is $49.44, including shipping. I don't think any online store can beat that price (including shipping).

Be aware that even on http://www.sparkplugs.com they have listed the incorrect sensors for the FGY33. Always best to call.

I purchased the NTK Oxygen Sensor (Part # 24545) from rockauto.com to replace the rears. The site did not specify right or left but i got 2 of them.

I believe the leads are different lengths R and L.

Unfortunately, RA doesn't know shoeshine from Shinola when it comes to Q45.

I just checked ngksparkplugs.com and the part number for both of the post catalyst o2 sensors are the same (24545). For the pre-cat sensors the part numbers are different from left to right. I guess the front o2 sensors are not interchangable while the rears are.
