"I installed the larger JET MAF sensor on a '99 F150 4.6 v8 (w/ 109,000 miles) to see if it helped with the stumble I was having when you would goose it in 3rd & 4th gear. So far it seems to be helping and is probably what I needed in the first place since I have an intake and Borla exhaust system on the truck. The JET works really well with the intake! I have not really noticed any power increase, but the computer may still be learning the new curve. I am pretty sure my gas mileage went way up though, because I just got back from a 106 mile hilly trip and used only about a quarter tank of fuel!! (I normally only get 300 per tank if I'm lucky). So, we'll see- but I'm happy with it so far!" —Royce C from York, PA bought a Jet Power-Flow Mass Air Sensor for a 1999 Ford F-150, 4.6L V8, 8th digit of VIN = W.
