Yup it does. Basically any mods that add hp/tq to your car is gonna make your fuel economy worse. An intake is not gonna do much so i wouldn't worry about it.

This is not an accurate reply.

Fuel economy actualy gets better, less strain on the motor to develop power to accelerate the vehicle.

It gets worse because people are more tempted to go WOT.

My economy improved by 2 or 3 MPG since the Injen install. I hardly ever go WOT.

I agree with the last 2 posts, fuel economy actually gets better.

Mods that help the engine work easier [less hard to pull the air in, push it out] is going to increase efficiancy, which increases milage.

Not true IMO!...the engine dosn't stain to suck in power, it simply doesn't suck in enough with a bad intake.
The nuber one thing for making horsepower is how much air feul mixture you can cram into the cylinder. A turbo for instance does that,but it can only make as more power as there is feul to compensate along witht the increased air.
Intakes are no different. The only thing Taht I think will add a positive power increase without sacrifising fuel economy is. pullies and lighter wheels. These requier less power to turn hence more power available for the drive wheels at the same fuel consumtion. As with the lighter wheels, engine works less to spin the wheel more power to the ground.
IMHO

There are few other threads from the past I remember.. basically.. it depends on how you drive AFTER you get the mods.. people that say mod makes mph sucks.. only because they don't realized they have changed the way they drive..

For myself.. I can honestly say my MPH is better after V2 installed when I drive modestly.. BUT.. since I feel so much pull.. I tends to floor the car a lot more now and of course.. kills MPH..

Case in example.. drive from LA to Vegas and back last week.. it is about 250 miles drive.. when going Vegas, it was clear and sunny and my avg speed is about 100mph, and high was about 115mph.. I floor and brakes a lot (moving between traffics, etc).. in the end, I killed a full tank of gas.. so 16m/g

On the way back, it was dark and raining like hell.. I drove slow and avg speed is about 70mph.. with very little accelerations.. most constant speed (+/- 5mph) all the way to LA.. in the end, i only killed a little more than half tank.. so definitely 30m+/g

An intake won't affect your warranty, unless its proven to cause problems.

As for weather it affects fuel economy, no. Consider that at 3000 rpm and 50% throttle, a 3.0L engine is sucking in roughly 37L of air per second (assuming 100% VE). That's not a small volume of air by any means, and there most definitely is "strain" by the engine to suck that air in. Nothing is free. So what do you think would be less restrictive? A factory intake system with all sorts of baffles and resonators and twists and turns which air has to travel through to keep things quiet? Or a nice and relatively straight path with a K&N filter, but at the expense of noise?
