Jet Power-Flow Mass Air Sensor Reviews

A great alternative to replacing your OEM MAF sensor

Reviewed By Thomas B (Brighton, MI) Reviewed for a 2003 GMC Sierra —8/5/2010 6:04 PM

If your OEM MAF (Mass Air Flow) sensor has went bad, and you like putting after market performance parts on your ride, I would go with this JET MAF sensor. Especially if you have a CAI (Cold Air Intake) and if your ride is chipped or has a performance tune. It nicely complements these parts. At first I thought my OEM MAF sensor was bad because of rough idle / stalling, so I bought this sensor. While I was awaiting the part, I decided to clean the throttle body intake with CRC throttle body cleaner and thorough clean my CAI (only oil the outside as too much oil can cause MAF and other issues - CEL (check engine light)). I also cleaned my OEM MAF sensor with some CRC MAF Sensor Cleaner (don't use carb cleaner or other harsh cleaners). Afterwards, everything worked like a charm. I still installed the JET MAF sensor for the little extra low end torque and I'm keeping the OEM MAF sensor just in case. But if you had the same engine trouble I had, do what I mentioned earlier and you save some money by not having to buy another MAF sensor. I decided to spurge and got a little more performance out of it since I already have the other upgrades on my truck. Overall, I like the MAF sensor and it just costs a little more than an OEM sensor, so if you have to buy a MAF sensor, might as well go performance part.

Fixed check engine light!

Was easy to pop the old maf off and replace it with this new one. Was relieved to resolve a check engine light that would come on intermittently. Thank you autoanything
