Great Addition
Cody from CARiD talked me into this for my 2015 Xterra Pro 4X. I already had the 63 K&N. My first thoughts on the K&N were lackluster. I had an AEM Brute Force on my 2006 Xterra. It was really loud when I hit 4K rpm but seemed quicker. (Noise? Maybe). The box got stress cracks from vibration so I had to remove it and weld it twice. I went with a K&N this time in spite of not being a fan of oiled filters because it boasted 14 hp. It was quieter than the AEM but didn’t seem as responsive. (Imagination...expectation...butt dyno?). I read where the MAF is a waste of $$$ but after driving with the K&N for a week and then adding the JET MAF, my vehicle was much more responsive especially at lower rpm. I kept the stock MAF just in case but I have had no issues with the dreaded CEL. I just finished the MagnaFlow cat-back and couldn’t be happier. Thank you, Cody and CARiD.

ECM still programmed to stock data. So if you buy JET MAF sensor, intake and exhaust you must tune ECM to get what you expect. I recommend Bully Dog Platinum GT. Without tune you will run lean with minor extra torque. Good luck guys.

So far so good. Installed sensor to stop trouble codes after installing a cold air intake codes were egr slow response MAF sensor and occasionally NOX sensor so far so good codes haven't appeared since installing Jet MAF sensor.

This thing was so easy to install and it worked amazing on my 2005 Infiniti G35. I gained instant horsepower and fuel economy. It’s what I needed to add the extra boost. The really amazing thing was that it allowed my cold air intake to stay cooler than before when running at high speeds!

I needed a new mass air flow sensor, and saw this one and thought I would try it. And wow, it really works. I am very happy and impressed and glad I got it.

Great Product
The Jet Powr-Flo mass sensor was shipped & received quickly. It was properly packaged & arrived exactly as it looks in the picture. The directions were clear & easy. The installation took about 10 to 15 minutes with no issues other than the special "star headed" screws that Chevy uses to keep consumers from working on their own vehicles. I just happen to have the correct drill screw bits in my tool chest. The Jet Powr-Flo mass sensor immediately added 2 mpg to my city driving. I can't wait to take a long trip & see how many mpg it adds to my highway driving. I added the Jet Powr-Flo mass sensor to my K&N cold air intake system. It was exactly what was needed to optimize the cold air intake. Great product that performs exactly as advertised.
