Cheap ebay.

 

Hello!

Gotts Mod, as Sir Shotgunz kindly & oh-so-helpfully linked to. Save the $$ you would have spent and bank it towards a custom tuner.

Or beer

Just thought Id pass on a little info I learned. When the 3V 5.4s first came out there was some problems with some people experiencing lean conditions from running CAIs. Most of the big companies went back and redesigned their intakes to solve these problems. One thing they recommend is to disconnect the battery before restarting the truck so that the engine will remap the fuel parameters based on the new airflow. Although all trucks and engines are different most of those early issues are non existent as long as you purchase the proper part number for your year of truck. AEM for example has different part numbers for 04 and 05 than 06 and 07. I have heard of many people running CAIs with tuners and canned tunes with no problems.

 

I can only recommend the AEM Brute Force as that is the only intake I have had. Here is a video about the AEM design process. AEM Design


This is the one I have. They used to call it silver, now it is gun metal grey. It matches my DSG lower on my truck. Pretty sharp.

 

Hello!

While I agree in principle, please keep in mind that time-to-market pressures, budgets and resources preclude the CAI makers from testing that many trucks. Usually, it's only 2 or 3 vehicles.

Couple that with the HUGE added complication of dealing with hundreds of different strategy codes for each model year F150 - some good, some not-so-good, and you have a situation where the compromize solution supplied for the intakes still results in a number of truck running outside the safe envelope.

Also - clearing the KAM does absolutely nothing if the MAF transfer function is not spot on. Nothing. It is NOT something that can be relearned - it's a hard-coded lookup table - again exacerbated by whatever pre-existing condition the strategy has in the first place.

The most respected tuners - having specialized in the platform, have R&D'd hundreds, if not thousands, of these trucks. Hence - the acquired knowledge base is far deeper than any CAI manufacturer has.

Call any of these guys & discuss. You will be amazed.

Lastly - none of this touches upon product quality - it matters not if their MAF venturi design is 100% copacetic, if the CAI lid deforms or other underhood components degrade or melt under normal use!

OK - real last time - you will NEVER know for sure (as a CEL or lack of same is not indicative) unless you actually have yer A/F's measured.

And - just fer chits & giggles, I'll post this yet again - as it says it ALL.

From VMP Tuning's website:

"We can tune for different cold air intakes on 05+ Mustangs and 04+ F150s. Any aftermarket intake that flows well and puts the slot-style MAF sensor into a larger less restrictive housing is going to REQUIRE a tune for the vehicle to run properly. Intakes that do not require a tune are often just as restrictive as stock and do not result in large power gains."


You can argue/disagree with me all you want. Don't care. I sleep at nite because I know EXACTLY what my MAF TF looks like; what my A/F's look like. But you can argue or disagree with the top F150 tuners, only at your Peril. You are simply not qualified.

The LAST entity I would believe is the CAI makers themselves - they wanna sell you an intake - otherwise they DO NOT GIVE A CHIT. Period. Dot. Dot.

So why would it be that some trucks have issues and other dont?

 

Hi again, sir!

That, sir is the million dollar question!

Believe me, it befuddles & frustrates the custom tuners to no end.

There are some members on here who have witnessed these anomalies first-hand - Marc Carpenter comes to mind. If you do a search - the TP Dyno Day threads discuss it quite nicely.

The PCM strategies 'misbehave' and the tuners are forced to spend inordinate amounts of time on them - and they are not even consistent within the same strategy on occasion.

Ford seems to have 'blessed' the F150 platform with more & different strategies over the years than just about any other platform you can name. Why? You'll have to ask Henry It's the reason that the database updates from SCT for their professional custom tuning software is so friggin' large.

The orther facet to this story is of course the truck IS running unsafe, but the CEL is not triggered. Only way to know? Direct measurement. Happens more than you think.

I hope this helps a teeny bit.

Cheers

So what should a person be looking for as signs of running UNSAFE?

 

Gotts mod/DVW mod. Both the same thing. Do research with the search on here for Gotts Intake Mod. Asking small questions repeatedly around here wont aid ya much help so its for best bet.

For an intake, you need to keep it enclosed for best performance. The Gotts Intake Mod with a free flow filter is as good as any of these $300 fancy loooking intakes. K&N & Volant is crap, S&B, AEM, and AirAid is the only kits worth looking at in my personal opinion. But overall they are a waste of money unless you make a good income and want to help their company out financially and to have a cool looking intake. Gotts is all you need.

misfiring, idling rough, a little power loss, or in the worst case, a blown up 5.4L

 

I want to thank everyone with there input seems like theres more bad than good with these intakes i think im going to try gotts mod thanks agian

 

^ Good idear.
