KN air induction kit

Many folks mentioned that if it was such a great deal, why didn't GM just install it in the first place? Well, I really don't have the answer to that, but I do remember back in the '70s when all of our new cars had to meet the new emmisions restrictions, and most of those cars were so choked down with vacuum leaks that they would hardly run. The dealer that sold that new car could not do very much about it, but an independent auto repair shop could "re-route" those vacuum lines, plug off most of those leaks, advance the timing to where it should have been, and turn a very sluggish large V8 engine into something that was almost wild, and improve the miles per gallon, all at the same time. Go figure.

Many oem vehicles have very restrictive air intakes, usually for the purpose of keeping noise down. How much power loss for how much noise reduction varies tremendously. There is no set rule for this one.

Have this guy show you the restriction, or pull back the fender liner and look for yourself.

OEM mufflers are another one where power is sacrificed for noise. One of my trucks had the muffler necked down internally to about 3/4" pipe diameter for noise reduction. The power loss was appreciable, to say the least.

But if it was that easy to raise mileage and HP wouldn't the auto companies set them up that way from the factory?

Just wondering?????

An engine is just an air pump the more air in the more air needs to get out for better performance and mpg. Start with the exhaust and THEN an intake kit. You can make yours better by just removing the glued on insulation on the fender. This will make it easier for you intake to get the coolest air possible off the front of the truck.

I get better mileage in the summer(warm air)than I do in the winter(cold air).

All other things being equal, cool moist air will give you more power (and theoretically, better mileage) than warm dry air.

• air flow

Drive ya nuts listening to all that air and dirt entering your engine. I mean, they are loud like you wouldn't believe!

Son put one of those on his 2002 F250, 5.4 liter and other than spending slightly under $300 and having added some chrome under the hood it was a total waste requiring additional service and cost for oiled cleaner elements.

It seems something is rotten in Denmark!

Think I dropped something like $700 between the aftermarket dual exhaust and that darned air filter to get it back to normal.

I bought a 03 F250 gasser with after market daul exhaust. Had 35,000 miles on it. At 50,000 I had to put on new exhaust to replace the daul because it rusted out.

Muffler shop says it runs to cold to keep the moisture out with daul.

Went back to single.

1995 Dodge had 140,000 and had the original exhaust.
