Seriously, I think its awesome you guys are enjoying the AFe intakes. Just a few things to consider before dropping that much cash. Or at least what I
consider. To me it seems like a gimmick...
Don't you think that Toyota would have engineered their intake to be the most efficient? Having 5mpg increase on the sticker would increase sales
dramatically. Having extra 20hp would too.
Mathematically, how would the engine benefit from a cone filtered intake? The drag difference between stock and AFE is negligible (assumption).
If it were a true cold air intake, I could see it increasing power, but not MPG. Stoichiometric ratio of fuel and air do not change. If your pulling
in more air, your engine will inject more fuel. (Colder denser air would thus require more fuel, but increase your power, potentially).
I feel that a larger intake like the AFe would only be beneficial if you were to combine that with a larger diameter intake tube, Mass/Volume Air flow
meter, butterfly valve/Throttle body, higher flow injectors and possibly a chip to retard timing.
Basically I'm saying is that the engine is calibrated to suck in a certain amount of air, and it in itself is the bottle neck. Its like putting on a
fire hose on your home spigot...? |
