Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.Reference NumbersACDelco: 213-2965, 213-2969, 213-3098Bosch: 13610, 13664, 13669, 13670, 13671, 13711, 13714, 13718, 13877, 15123, 15301, 15303, 15304, 15305, 15307, 15469, 15504, 15506, 15510, 15511, 18126, F00E260991Chrysler: 05149169AA, 05149171AA, 05149283AA, 5033-200AA, 5033500AA, 5149-171AA, 5149169AA, 56028994AA, 56028995AA, 56028995AB, 56028996AA, 56029049AA, 56029050AA, 56029112AA, 56031110AA, 56041698AA, 56041699AA, 56041702AA, 56041846AA, 56041847AA, 56041887AA, 56041944AA, 56041950AA, 56041951AA, 56041952AA, 68243213AA, DS56031110AADelphi: ES10596, ES10882, ES10916, ES11003, ES20093, ES20206, ES20208, ES20210, ES20228DENSO: 234-4030, 234-4217, 234-4228, 234-4229, 234-4230, 234-4232, 234-4546, 234-4547, 234-4553, 234-4559, 234-4579, 234-4586, 234-4587, 234-4588, 234-4594, 234-4598, 234-4766, 234-4770, 234-4771, 234-4772, 234-4796, 234-4943Dodge: 56029112AA, 56031110AA, 56041702AAJeep: 56041846AA, 56041847AA, 56041950AA, 56041951AA, 56041952AAMopar: 56028992AA, 56028994AANiehoff: FE80429, FE80562, FE80568, FE80569, FE80570, FE80574, FE80575, FE80576, FE80770, FE80870, FE8760, FE8814, FE8816, FE8830, FE8831, FE8833, FE8965, FE8969Omnicraft: QDY1, QDY10, QDY24OMNIPARTS: 19060391, 19060392Standard Motor Products: SG1381, SG1387, SG1388, SG1389, SG1393, SG1394, SG1395, SG1589, SG1685, SG1849, SG1852, SG1853, SG659, SG663, SG717, SG719, SG733, SG734, SG736, SG740, SG867, SG871VAICO: V10-76-0123, V10-76-0125, V30-76-0048VEMO: V10-76-0123, V10-76-0125, V30-76-0048Walker Products: 250-24253, 250-24345, 250-24460Wells: SU3264, SU3266, SU3269, SU3283, SU3286, SU3287, SU3295, SU3297, SU3298, SU3337, SU3338, SU6886, SU6887, SU6893
