    Does it help your gas mileage at all. I am getting 18 in my 4.0L tacoma with 33in tires with a manual transmission. Is it worth getting?

    No, if your a mpg minded driver I would just stay with the OEM intake.

    I'm not really mpg worried. Does it help the truck out any more than the OEM one?

    It doesn't do anything for the truck but roar at a higher rpm.

    I'll keep posting this link as needed.

    At almost anything below Wide Open Throttle (WOT) the throttle plate is the overriding restriction to the intake making the air filter insignificant to air intake. With fuel injection and a computer controlled loop with intake and exhaust feedback, if the air filter becomes clogged to the point that WOT suffers then power may be lost but fuel economy will actually increase with less power.

    http://www.fueleconomy.gov/feg/pdfs/...02_26_2009.pdf

    The study concludes the conventional wisdom that a dirty air filter can effect the mpg of a carburated vehicle but it also shows that an extremely clogged filter doesn't reduce mpg in a fuel injected engine.

    So far I haven't heard a plausible theory on why this lab would want to fake this result as some would like.

    Quick synposis for those this will never even check out the link.

    3 different fuel injected vehicles were tested with brand new filter, and then progressively restricted filters to the point of gross restriction and actual collapse of intake tube due to restriction. Results, no decrease in mpg and slight decrease in horsepower in the worst restriction.

    So a less restricting "drop in" can show a slight increase in air intake at high rpm and make more power but more power takes more air and fuel so more power almost always means more fuel.

    Pretty much the same thing with an exhaust, and they can hurt your low rpm power which is where you get good mpg anyway.
