Fits perfectly, does its job
This was an exact fit for an 03 altima at a fraction of the price. Keep in mind that after installing it you must do a few relearn procedures or your car will run poorly and eventually break down if you continue to drive it without relearning.

Its recommended that a shop do some diagnosing. Though you may get a check engine light and you get a mass air flow code does NOT mean this part is bad. It may be a "related" part causing the problem. Some symptoms may be but not limited too, engine stalls soon after starting. engine drags or hesitates when idle or under load. hesitation and/or jerks during acceleration. unusually lean or rich idling. check engine light

Your car will run extremely rich, smoke out of the back, etc. There was a recall in this era of Altima, make sure there isnt further damage inside the engine itself [recall states the cat converter substrate breaks off, marring the inside of the engine] this mimics the symptoms of a MAF failure, however, it was a larger, much greater internal problem I later found out....Good luck!
