Nissan G25 2.5L Front and Rear Oxygen Sensor Set 22693-1MR0A+211500-7500 Pair Replacement

This front and rear oxygen sensor set directly replaces Nissan OEM numbers 22693-1MR0A and 211500-7500, cross-compatible with 258006294, 8200033618, and 16987 among other models. Universal for Nissan G25 2.5L engines, specifically for 2011-2014 models. Replacing resolves high fuel consumption, acceleration hesitation, and persistent engine light; particularly for older cars with 80,000 km plus sensors slow to respond, causing poor mixture control and exhaust overlimit. If idle unstable or exhaust emits black smoke, or fuel consumption rises by two levels, likely oxygen sensor aging; replace to protect the catalytic converter.
