Guys,
I have a 2005 Integra Type S. It is a K20A3 auto with tiptronic. I need the air fuel sensor for it. My problem is I don't which one to get because the RSX Type S is a manual with a different variant K20.
I need help please. My car runs like crap and burns way more fuel because of it.

 

In the US, there is no such thing as a Type S with an automatic transmission... they are ALL 6-Speed manuals. Where are you located and what Country/Market is your vehicle from ?

 

I am in Jamaica but my DC5 is a right hand JDM variant.
I was looking at the Denso sensors that work with the base RSX, since those seem to be the closest to what I have K20A3 Auto. Don't wanna expiriment with USD 100 plus custom/duty/import charges, hence why i am checking here first.

 

Why is this so hard to find?

 

what part numbers have you found that closely relate?

for the USDM 2005 Base RSX I found :

36531-PND-A21 $315.94

36531-PNE-003 $405.57

The part numbers change from the 2004 to the 2005.

Have you checked JAPANESE GENUINE OEM PARTS CATALOG?JP-CarParts.com for the part numbers they have on the Japan market?

 

The NTK sensor is a quality replacement if you want to save some money. The part number for your application (K20A3 with Auto transmission) is: 24694. You can find them on Amazon, EBay or RockAuto.
