### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Put it in and it worked
  

*by D***S on Reviewed in the United States 🇺🇸 on June 24, 2014*

Had a problem on the air intake side of the engine and had replaced the IAC.  Although the engine light is still on, the car is getting 30 mpg and as the mechanic who fixed the back engine mount said, how bad can the engine be if it gets 30mph.  The antiknock sensor codes have been on and I will maybe replace them but the V6 engine antiknock sensors are hard to reach.  The MAF works fine and it was the cheapest I could find anywhere on Amazon.

Installed on a 1997 Lexus ES300 V6 1MZ-FE was plug and play I wish they would have included a new maf gasket too I tested my old original 230k+ miles denso maf sensor and it was out of spec didn't throw a check engine light but decided to replace it anyways since it was out of spec didn't notice any difference with this new sensor but it works just fine.Dorman maf sensor failed on me left me stranded with $300 tow back home next time just buy a oem maf sensor
