in need of O2 sensor for the rear. Need a trusted site to order from.

Rock Auto.com is cheaper than any parts house around.rock auto 85.00-----autozone same sensor,same part number $175.00 go figure.only thing is,you have to pay shipping,not much.i figured shipping for my zip code and it was $3.29,1-6 days.2 day was $11.59.good luck.they have several different ones,upstream and downstream,also different brands.i think the denso is oem.good luck

Amazon.com is where I bought mine about 6 months ago $49 Name brand. Much cheaper than Auto zone. Ive ordered from Discount auto parts.com also. They have reasonable prices and an 800 # if you have questions.
