Not sure which 2009 Chevy Malibu Mass Air Flow Sensors are right for you? We have over 316 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"This product installs quite easily and in the case of my Impala seemed to invigorate the 3.9L
and smarten the transmission somewhat, meaning that it downshifts more readily and remains in a lower gear for a more appropriate interval. It does look suspiciously like a stock MAF unit sans the filter screen and if it is nothing more then shame on Jet for exploiting its customers but assuming the best for the moment I will state that this product has made my car more pleasurable to drive and has not caused an appearance of the CEL. It works wonderfully with the Jet stage2 performance module,CAI and aftermarket exhaust (I have Magnaflow.) The slight increase in fuel efficiency is an added bonus." —Darren T from New York, NY bought a Jet Power-Flow Mass Air Sensor for a 2009 Chevy Malibu, 3.9L V6, 8th digit of VIN = 3.
