Hey guys, i just installed my KKM intake the other day and since then i have been getting terrible gas mileage. I have been driving consirvativley(sp?). I have not revved high or put my foot into the throttle at all. I was under the impression that i would get better gas mileage doing this mod. Am i just crazy? Any ideas would help me greatly! Thanks in advance guys!

No at idle it runs the same as before. Just a little bit of rough idle, but it was doing that before the install. When driving it doesn't seem that much different, just a little louder than what it used to be.

I plugged the vacuum lines. I really don't know about the MAF, but i was planning on cleaning it anyway soon. I reset the computer twice and still no difference. No spark plug wires came loose, so i'm at a loss. Any other ideas? Thanks everyone.

It sounds like its doing what its supposed to... It doesnt make a beasty gain of power. Just make sure its not over-oiled. That would cause a mound of problems.
How much gas-milage have you lost? Are you sure you are loosing gas milage? Gas milage shouldnt be affected that much.
Check your oil level, you might have a lower intake manifold leak... also check for some coolent around the backside of the engine and near the exhaust. Those are some symptoms of it.
Could be you getting more air, & since the ECU knows this is giving more fuel then before. That could be your drop. I had the KKM on 2 different X's & did notice a slight decrease in milage. However for me it doesn't matter a whole lot.
i HIGHLY suggest cleaning your MAS. it helps gas milage, idle, smoother acceleration and over all performance. you should do this ever couple oil changes now that you have an oiled filter.

I disagree....I have modified F/I Fords for years, and every car or truck I've put an intake or CAI on got better economy and power, however slight. Since the air increase is BEFORE the MAF, it is corrected to the right (Stoich) voltage, so that is not why economy decreases. If the MAF is screwed, or he has a leak in piping or vacuum, then the computer cannot correct for it, and it will run like poop.
Sorry to rant....just my $.02

Power... ah, probably not...
