#862 of 864 The Generation II FIPKŪ is K&N's & Granatelli MAF by ttaupier1

Sep 28, 2009 (8:42 am)

Information share:2003 GMC Sierra 1500 5.3L V8 (SLE two tone)
 
I have had a K&N: 57-3021-1: 57 Series FIPK > Performance Intake Kit for about 5 years, I do experience on average 17.4MPG, I recently bought a new MASS AIRFLOW from Granatelli, for $300. While i took out the OEM MAF i notice how similar it looked to the factory stock part. (I took photos) I disconnected the battery as instructed, and installed the part "in front" of the K&N kit (behind the air filter). The truck does seem to idle better and accelerate more smoothly, mileage over the past few days is averaging 18.5MPG (city and highway combined), I use 89 octane fuel, and cleaned the air filter a week or so ago.
 
The concern I have is that if looks like an exact replica to the original Delphi unit i took off, Granatelli just machined two slots in the cross bar and eliminated the back side of the black plastic wing, they also seemed to just machine the Delphi metal name plate and replace a sticker with etched part number, but in essences it look identical to the OEM part you can get for $124.00, might be worth just riping off the front screen of the OEM and see how the flow increase works.

That alone could account for the mpg increase.
 
Try putting the OEM MAF back on with an OEM paper filter and you may see 20.
