15664 Premium Original Equipment Oxygen Sensor - Single

Works great. OEM replacement guaranteed to work

Worked perfectly in my 2006 F-150 XLT with 5.4 L V-8. The check engine code was cleared after changing this out and has not returned. Out of the 4 oxygen sensors on my truck, 3 of them were right out in the open and easy to get to. The 4th one (the one I had to change of course was located up behind the exhaust pipe with some structural members and the transmission oil dipstick pipe in the way. Had to remove a few things and still needed to get my 8 year old son with much smaller hands to reach up in there to unplug the old sensor then plug in the new one. Good thing this sensor fit right. I have since traded my truck in on a newer model so I can't comment on whether the sensor will last as long as the original one.

This Bosch o2 sensor solved my check engine and missing problem on my 2010 Ranger. It was so much cheaper than buying it at a store I was concerned. It works great and the truck runs perfect now.

Well made part. No issues fixed the code problem

OEM match

Replaced these 2 O2 Sensors and they worked perfectly. Bosch quality worked the first time. Fuel Mixture changing much faster than my worn out ones.

Fit perfect on Ford F150 2WD 4.6 single exhast, needed 2 of these and 2 of the 15717,ran as expected, also got order with in 3 - 4 days with standard shipping. Also CHOCK TIRES and hit the parking brake. Just to be sure before I ordered jumped under neath it to ck that it was the correct one. I hit the shiftier with my arm (VERY sensitive, can push it with my finger) and it jumped into Reverse, wasn't running but was on a hill, damn near ran me over. Amazing that you can shift it with it locked in park.

2010 Explorer 4.0 liter. Got DTC of P0155 (Front, Driver side). Got two Bosch 15664 sensors from Amazon. Put one in each front position. Did proper "reset". One (Front, Driver side) still produced code P0155. I "reset" again after a few days of driving. Erased code several times over several days. Checked electrical connections and tightness of unit. No improvement. Got another 15664 (for triple the Amazon price) at a local retail auto parts store because delivery of another 15664 from Amazon would take two-weeks. Put in retail store sensor after removing Amazon/Bosch sensor. Problem solved! No more check engine light. No more DTC on scanner. Looks like one of the two Amazon [Bosch] sensors was "bad". So, one-star given. I would have ordered another 15664 from Amazon due to very low price and even tho one was "bad". But, needed the sensor "right away". Amazon does not offer any return or refund on this part. The 15664 is for front, both sides for my vehicle. Rear/downstream is "15717" (Bosch). Good luck!

Fits and work good

Truly is an OE type sensor. Missing the locator pin on the connector so it will fit upstream or downstream locations. Arrived quickly. Fit perfectly. Installed about a month ago. Very happy. Would order again.

Excellent product

Installed these in a 2007 Ford F150 and they work great. All CEL's related to O2 sensors have gone out, would buy again if needed.

It fit perfect but my fuel mileage was hit low couple of miles.. don’t know it was the sensor or not
