Denso: Plug in the outlet!

EDIT 4/27/15 Heater failed prematurely after about 4000 miles. I can't find any guarantee. If that fails, I'll reset the token. Direct replacement for '07 CX-7. Supplied with a copper-based anti-seize coating. It would be nice if there was an oxygen sensor connector as well.

Pros
  • This is amazing
Cons
  • Almost OK

Delivery time this one was quick not like the other 5014

Great product I fitted this to my 2007 Mazda Cx7 it cured my bumpy idle complaint. These broadband AFR 02 sensors typically last around 50,000 miles before they start to show fatigue. Highly recommended for all owners of MZR DISI TURBO Mazda engines.

Pros
  • Sleek design
Cons
  • Good mostly but...

Worked perfectly as an OEM (Mazda CX-7 2008)

This was an exact replacement part that worked great on our 2008 Mazda CX-7. In addition, the problems with codes and fuel consumption that the car suffered from were fixed. Quick tip: check your electrical connections and unclip them from the base connectors to get them loose. This may be a "blind" operation in a limited space, so study the details before entering; The replacement is exactly the same as the OEM version.

Pros
  • Several competitors
Cons
  • Update available

Failed Prematurely - Replacement Parts

Bought to replace a factory sensor that was soaked with oil due to a turbocharger failure on a 2010 Mazda CX-7. Driven the vehicle two short trips (<50 miles) and received a heater fault code (P0134) on this sensor. Took that sensor out and replaced it with a factory oil soaked sensor - the code went away with no problems. It's pretty sad that the old oil soaked sensor is doing better than this new one. Read other reviews before you buy this one. I waited weeks for the installation so the…
