I didnt read the details close enough when initially purchasing for my 2006 Honda Element.I received two sensors and the downstream worked but couldnt figure out why the upstream was not.After reading the details, turns out the upstream sensor is only good for 1999/2000 Civic.Best bet for the Upstream would be OEM (Denso); 22mmFor the price, still the best deal I could find for the Downstream sensor, so would definitely recommend if that's what you are needing.Upstream:1999-2000 Honda Civic EX L4 1.6LDownstream:2005-06 Honda CR-V L4 2.4L2003 2004 2005 2006 2007 2008 2009 2010 2011 Honda Element L4 2.4L2002 2003 2004 2005 2006 Honda Insight L3 1.0L Manual Transmission Center

Replaced O2 sensors to get codes to disappear. Didn't work(they don't read at all)and broke the wire on old one taking them out. So it wasn't a win for me and I coukdnt get a replacement cause I couldn't take them back out to return

Put the new ones in and still getting the oxygen sensor codes.

Trash items don't fit. If you see this review please don't buy you will waste your money. Look elsewhere. Wasted my time and money.Updated: even more angry, d16y8 doesn't fit two female plugs like other reviews said. Please please do not buy look for other options. Save you my pain fk this company

The female whorls fine but since I was sent two females. Not an inward and out word I am Betty dissatisfied. I live in Costa Rica had it sent to Colorado than flown here by a friend to Costa roca only to find out now that the part are wrong. Shame shame shame

These are the exact same. Do not work for a honda crv. These are male only. I need a male and female for upper and lower. Not sure which one is which but only 1 will fit.

These were supposed to be an upstream and down stream o2 sensors. Both are downstream and could not be installed.

Beautiful clean products that got my honda crv running to profection again 👏🏽
