These are NON-OEM replacement oxygen sensors designed as a "specific use" application. Huh? Basically, they are drop-in replecements for the sometimes-very-expensive OEM O2 sensors - they thread right into the stock bungs, and have the same plugs on the other end so there is no splicing necessary to get it installed. You may find some variation in the length of the wires, but the plugs will mate and the sensors will fit. And the wallet will be happy. :-)
Our cars are getting older! In efforts to keep them running better, the oxygen sensor is often overlooked. Over time they can get buildup on them (they are in the exhaust path!) and actually lose their sensitivity and accuracy. This can result in poor engine running symptoms. At the very least, fuel mileage can actually suffer from a "lazy sensor" - a major consideration with the price of gas now!
Please cross-ref your vehicle and order the appropriate sensor.
