Fixing your stalling issue on your 350Z
Saved myself a ton of money by finding out this was all I need to fix the stalling issue on the car. Fast shipment, plugged it in and the car started right now. Just needed to reset the ECM.

OEM sensor, w/ tutorial on how to put it on correctly
100% OEM, turned off engine light as soon as i plug it in, really cheap and fast shipping, worked with my nissan murano 2005, should work for most cars of the same v6 engine. Just make sure you disconnect the battery for 10-15 minutes and once the time is up you honk the horn or turn on the lights to make sure the whole system is drained of power. Then replace the sensor using a T20 tamper proof bit, make sure the sensor faces the same way as the old one, the little glass wires should face away from the throttle body, and towards the intake filter. Hand tighten the screws, then plug in the battery and start the car up. Worked perfectly for me.

Solved My Engine Shutdown Issue โ Perfect Fit for 2005 Nissan Murano
I was experiencing a dangerous issue with my 2005 Nissan Murano: the engine would randomly shut off while driving, especially when coming to a stop or slowing down. After some troubleshooting and attempts to clean the original MAF sensor, I decided to replace it with this Hitachi sensor, and the issue was resolved immediately. Since installing this MAF sensor for myself, the engine runs smoothly, the idle is stable, and it hasnโt shut off once. This part is clearly OEM-grade, fits perfectly, and no additional setup is required. It restored full reliability to the vehicle. If youโre dealing with engine stalling or shutdowns, this sensor is highly recommended. Donโt waste time trying to fix a failing sensorโreplace it with Hitachi and drive with peace of mind.

Does not fit my car even though the description says yes
The description is incorrect. It says it fits 2013 Altima on the paper coming with the sensor. However, this has 5 pins while my car has 4 pins. The plug is also physically incompatible.

New brand for Hitachi is now Astemo Hitachi
Installed and everything working great. One thing i noticed is box and sensor says Astemo instead of Hitachi. Papers inside says the new company is now called Astemo Hitachi now. Well see if I encounter any issues later, but so far everything is working fine.

2012 Nissan Frontier V6
Bought it for my Nissan frontier bc the OEM kept having check engining issues. Found this one, cleaned it, plugged and play and boom done! I will say - disconnect the battery! Also reset your learning program donโt freak out like I did lol. Just type in YouTube and youโre set. Seems like no one knows how to do it but itโs SUPER easy!

2012 Nissan Versa 1.6L Compatible. New brand name Astemo (Hitachi conglomerate). Perfect so far.
Was recently having some issues with the car randomly stalling and idling problems. Been chasing this problem for about 5 months now. Damage to the old MAF was caused by a mechanic that did some valve cover work, which was very horribly done. Code that was always flipped was the P0300, which can be basically anything, so its hard to chase electrical issues. But this may finally have solved it! Played around with the old MAF, and there were signs that it was the problem. This sensor worked right away, plug and play basically. This is a new brand name of Hitachi, called Astemo now. Made in Japan, and it is the OEM manufacturer for the car. So far no issues, great product, and I hope for it to work long term. Overall 5/5! Luckily I did not get a used/old product as some others have said. This was brand new in package. Car is a 2012 Nissan Versa 1.6L. I added a picture of the compatible cars that is in the package.

it fit in Nissan versa Note 2014
I bought it the last January 13 2021, and today October 17, 2022 the sensor doesn't work anymore, so almost two years it worked. The Original worked for 6 years, so I need to buy I new one and I thinking to buy the original part.
