Honda CRV 02 sensors and Honda Element 02 Sensors but will fit most K series vehicles pre 2007
Proven high quality replacement 02 sensors, two sensors included upstream and downstream. Fits multiple Honda vehicles including Element, CRV, Accord, TSX, Civic and RSX.
Not as pricey as Denso but not cheap ebay/amazon crap.
02 sensors are vital to passing emissions and having a smooth running vehicle that gets great gas mileage. Worth replacing
