CAIs really only work well in conjunction with several other mods such as a cat-back exhaust and/or headers. The downside to CAIs is that they can suck in water if you go through some deep puddles.

i would agree the cai it kinda makes a different engine sound. kinda like in the old days when guys would flip the top of the air breather upside down and think they were going twice as fast as before. most cars and trucks nowadays pull air from outside the engine bay anyway which is where the expression cold air comes from.

#859 of 864 Improved MPG, replace stock muffler, Toyota Highlander Hybrid by sebemismnusa

Jun 10, 2008 (1:50 pm)

What I have: 2006 Toyota Highlander Hybrid with front wheel drive, 3.3 liter 6 cylinder as found in many Highlanders.
  
Would a higher flow exhaust system, for example a Flowmaster muffler series 50 or 60 help, in addition to removing the twists and turns in a Highlander's exhaust system ? I have not found any catback systems for Highlanders. Would I really have to replace the catalytic converter, too? Or how would I know if the stock catalytic converter impedes exhaust gas flow? I also assume there are EPA regulations on catalytic converter replacements, too.

finding a catback system wont be necessary if you have an exhaust shop do the work. i dont think it would improve your fuel economy enough to justify the cost.

#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.
