Where to purchase a Denso oxygen sensor?

Hello to all and thank you for allowing me to join in. I'm from Tucson,AZ. Recently purchased a 2000 Toyota 4 Runner-SR5. Have a ck engine light on and need to repair it. Code calls for the downstream Oxygen Sensor to be removed and replaced. Does anyone else live near by and tell me where to purchase a Denso OS. I hear their the best OEM.
Also need to remove and replace the cabin air filter. ( where do I start first on the Cabin Air Filter) .

Thanks again, TucsonGuy56

 

welcome aboard. i've heard you can actually get a good price on the denso oxygen sensor on Amazon. Our trucks don't have Cabin Air Filters, so nothing to replace there.

welcome from a fellow 2000 SR5 owner!

 

Amazon!

 

AmaZON! Got both mine there.

WHERE ELSE, but Amazon....followed by Ebay, then local local auto zone, advance, Napa, etc

 

For sensors, I will always go to the TOYOTA dealer first. Next is the OEM manufacturer who makes it for TOYOTA. OEM shows up on Ebay/Amazon, but you have to be super wary of fakes.
