Looking for good brand oxygen sensor

Denso for sure, I just replaced the rear O2 with an Amazon Warehouse product ($42 delivered), had a damaged box, but the product was pristine. and it solved the P0420 problem post haste as changing the front one did not solve the problem, I paid a ridiculously small price compared to one with a nice box...here is a linkee for you, around $70+, a substantial savings. I also replaced the front O2, but paid the $90+ from Ebay.....did not check Amazon Warehouse, still kicking myself for not checking on the front one....

$146 Denso 234-9001 Upstream Air Fuel Ratio Oxygen Sensor with 10.6” 4-Wire Harness, for Auto Trans Equipped Vehicles

http://www.amazon.com/gp/offer-list...sr=1-1&keywords=DENSO+234-9001&condition=used

It says used, they have to state that when an item is returned...it has the same warranty as a pristine product, never had a problem with Amazon Warehouse deals, it is the way to go if they have it in stock....

Definitely go OEM (Denso for Toyota)...

Dealer pricing is way out of line for same product...

 

I've only used Denso for both sensors and coil packs and have never had a problem with them on any of the four tacomas I've owned over the past 12 years. Shop around. Rockauto is usually competitive/best price/fast ship.

 

I have also had good dealings with Rock Auto. They always indicate which parts of the selection are OEM. I prefer to use OEM when possible.
