Yeah not a good thing...the mod was intended for trucks with the type of air box pictured in the article here:

What is the difference in doing this and buying an aftermarket intake system?????? Are you trying to tell me the aftermarket intakes aren't increasing airflow, changing the air/fuel ratio? Then what the hell is the point of buying one? For looks?

 

The main difference is the "Gotts" intake was "designed" for a 5.4L 2V engine, not the newer 3 valve engines.

You seriously need to do some research... It is known and accepted that the vast majority of aftermarket intakes can cause the 5.4L 3V engines to run lean. That's how they are able to pick up a couple HP, but this isn't good for your engine in the long run. The only real way to fix this is with a custom tune. Troyer Performance or VMP can both get you quality tunes that will adjust for the intake. If you want an intake that will not cause a lean condition, you can go with the 3.0" AirForceOne.

The Gotts modification is a 3" also so I still ask; what is the difference?

 

3 valve motors are very touchy to intake mods-period

 

Jesus, I'll bet $100 you didn't even bother to click on the link I posted. All you did was zoom in on the fact that there is an intake out there that won't lean your motor out. It was designed specifically to that end.

I really don't care what you run on your truck, in fact go out and make a couple WOT runs for me!

Whatever dude. I don't think K&N and other companies would be in business still if their products were screwing up people engines. Go rant to someone else. I could care less about what you think.

 

Doesn't battery need to be disconnected for a while then the engine run for a while so that the PCM can "relearn" the fuel:air ratio once the intake is changed? I wouldn't think that simply changing intakes without the PCM adjusting itself would show any real data.

 

I was trying to explain something to you but your ignorance and refusal to read amazes me. Since you didn't click on the links I posted, here's the OP from that thread, titled "Lean AFR with K&N FIPK and Edge"

If you're so sure that these intakes won't cause a lean condition, please show us a dyno graph or other A/F data to back that up. Have you ever dyno'd your truck or do you think that's a waste of time?

Here's a snippet of the specific post I linked to, and I'm quoting Mike Troyer (owner of Troyer Performance, who has personally written custom tunes for probably hundreds of members here)
So I guess he's full of bullplop too?

PS: It's not just "what I think", this has been proven on dynos over and over. Do you happen to belong to the Flat Earth Society?

 

I never said it wouldn't cause the truck to run leaner. How many people have you seen say their engine is screwed because of the engine running lean due to an aftermarket intake? I haven't heard of one. And I hope it makes you feel like a badass calling people names over the internet. My 2 year old daughter can do that I guess she is a badass too.

 

just cuz the cel doesn't come on -doesn't mean it can't be running lean and taking miles off your engine-personally saw a stock 04 5.4 on the dyno running int h e 16-17-1 af line-the cel never came on-just saying-it's your truck-your choice

 

I didn't call you names, I said you are ignorant. Now, ignorant is defined as: So, in the context of how non-stock intakes can affect the 5.4L 3V engine, you definitely fit that definition, and unless you take it upon yourself to do some research (since you obviously don't want to listen to anything anyone tells you) you will remain that way. Now if your daughter is calling people names on the internet at 2 years old, you've got some serious parenting to attend to.

Maybe you didn't realize that I'm not trying to say that putting a K&N on will cause your motor to blow the next day. However, after continued use, you will cause damage to the engine and other components, shortening the life of the motor. Running lean will cause your EGTs to increase, also increasing wear on downstream components. Now if you're going to dump the truck after 3 years, who cares, it'll be the new owners problem right?

But, like openclass said, it's your truck, do as you like, we were just trying to inform you. Seriously though, I hope your daughter grows up to be more open minded than you are.

Alright, like the other guy said, it's my truck and i'll do what I want to it, why should you even care? If I come on here in 6 months and say my motor blew due to running lean, then yeah, call me a dumbass. But until then, who gives a *****.

 

Yes - That has to be done - definitely. Anytime you update or modify anything to do with Air Metering accessories, you want your adaptive strategies to readjust fuel trims and trans tables as well.. You reboot the PCM to accomplish that. - But, if the MAFs dirty, it doesn't matter. It will run like sh^t no matter what you do until it's clean.

 

So should the battery be disconnected (PCM reboot) if you clean your MAF as well?
