Just curious how many folks out there with a 4.0l have performed the MAF mod and with good results (and no stalling at idle, etc)?

Also anybody perform the foglight mod to a 2004?

I don't know because I have a 4.0l and it's a 2003. I'm still afraid to try it because i don't know how good the results in the end!! I will wait until I have money backed up for just in cased if the MAF mod screwed up and Ford refused to replaced it!

Of course they would refuse to replace it. And it isn't just a MAF it is also an IAT.

No offence but, I've heard couple of members at gen-edge (not sure who) and got their MAF senor replaced under warrenty even they messed with it!! I guess it got to do with good relationship with the Ford dealer and got away with it!! oh well!! lucky them for that!! lol

When they send that back to the warranty parts return center and Ford refuses to pay the dealer for the repair, they might catch on to you. But you're right, they won't find what they aren't looking for.

Well, I'll weigh in on this.

MAF mod on the 4.0 is much higher risk than on the 3.0 (where ther is virtually NO risk except the warranty issues Dave and Julie brought up). My 3.0 has been modded for almost 2 years and it runs fine (it's a 2002).

2004 MAF's are quite different. They have the MAF mod already built in, basically. The sensor is a different design entirely and results in much less blocking of the intake. I like it.

Yes, the IAT is in the MAF, but the MAF mod won't affect it. I would say about 1 in 4 of the 4.0 MAF mods I've done has had a problem, and about 1/2 of them were too much to live with.

There were some rare cases of MAF swaps by dealers after modding; but they were special cases where the dealer had an extra for some reason and they knew the truck owner well. Not something you should count on. Taking a hacksaw to your MAF is NOT covered under the warranty except by the grace of the service department!

So although I have done MAF mod's on 4.0's, I always advise against it. Many people want to do it anyway so I do it for them -- but no one can guarantee what the result will be. 4.0's are much more finicky about idle air metering than the 3.0 engines are.

Yeah, I love my MAF'ed 3.0l. I'll probably hold off on my 4.0l when I get it.

Thanks everyone for their input/experiences.

or
"N3ELZ + Hacksaw = More Horsepower!"

Or, to borrow from an old gun ad: "You can mod my MAF when you pry it from my cold, dead, fingers..."

That's by someone who is SERIOUS about their warranty!!!

Hey, Jeff! My weight is 215, down from 237 and still dropping (doctor's orders, don't ya' know...) Y'all won't recognize me at Centralia.
