I'd go with a K&N Cold Air Intake or air filter. K&N is a reliable brand and you don't have to replace the filters.

 

Been posted by someone else, most of the aftermarkets increase your intake temperature. The stock intake uses a little snorkel and pulls air in from the driver side wheel well outside of the enginge compartment. The aftermarket ones pull from inside after passing through the grill, in fact giving a bit of a temp increase, not any 'colder'. Also, in shotguns defense, if you actually look up the numbers, most of the horsepower gains that do come from the increased flow (yes there are some, even if its higher temp air) are in the 4000+ RPM range. On a truck, that range really isn't used much, you want more power in the 1k - 3k range...

Best thing to do IMO is remove the silencer snorkel, and fab up your own piece of open 3" pvc to fit back into the hole where the snorkel used to be. It will add some sound, some extra airflow, and still be coming from the outside of the engine compartment, look up 'gotts mod' for more info on how its done. There are some dyno tests on gotts on f150online somewhere and it shows some good improvement, moreso than the 200 dollar A/M intakes, and it only costs you less than 10 bucks and some time of doing your own custom fab work (which personally, i would get more satisfaction from anyways).

 

Sorry but that is a drawing created by Banks obviously which is not a fact sheet or dyno sheet but rather a MARKETING sheet... that is my point precisely. I would like to see true dyno sheets before I discredit CAIs all together. EVERYONE is going to say there product has positive outcome.

 

My 'facts' come straight from the automotive engineers that designed your entire truck - you know, the ones that get paid by FORD?

I'm not the one selling $350 'hotter IATs than stock' intakes that

1.a. provide (at best) 12 hp at 5000 RPMs (even though they typically dyno test them with the hoods up and huge fans blowing on them - so even those hp numbers are suspect)
1.b. do nothing for the average truck under 99% of the truck's engine load conditions
2. do not offer any MPG guarantees
3. have the potential to foul your MAF (oiled type) if improperly oiled
4. have not been dyno tested vs. the BRAND NEW 09-10 stock intake setup
5. potentially can void your manufacturer's engine warranty

Regarding your crayons remark - I suggest you leave the grade school tactics at home.

Personal attacks do not accomplish anything, add no value to the technical discussion, and only serve to make you look like a moron.

Wanna buy a Tornado?

 

again show me the facts. Of course Ford is going to say they designed the best solution. This way they don't have to train their techs in aftermarket maintenance. By facts I mean has anyone provided you with DYNO sheets of each and every CAI vs the oem? Not trying to be a d1ck here but TOO MANY people go on public forums a regurgitate what "They heard" not what they know. You may very well know a lot about the F150 and I won't discount that but what I want to see, to make an "educated" decision... is FACTS.... not theory

I wasn't trying to belittle you with the crayon remark.... but your "four people told you they suck why get mad" remark had no merit as well.... just wanted to make sure I covered all avenues of comprehension

Tornados aren't in question here

1. You need to re-read this thread. I never personally attacked Steve.
2. I have been asking Steve for A/M MANUFACTURER dyno sheets and A/M manufacturer guaranteed MPG increases. I then offered to help him pick the best A/M intake based on the A/M intake dyno sheets. I already have the stock dyno sheets for the 09.
3. Here's the dyno sheet that K&N offers for the 63-2575
- which is the only intake they offer for the 2009-10 5.4L. Notice the dyno sheet is for a 2007 Expy (which has a totally different intake system)? Hmmmm...Wonder why they haven't done a dyno run on the new 09-10 F150s? Could it be that the hp increases are even less?

 

no one is saying you are attacking anyone. I am not attacking you... I am simply asking for PROOF to your claims... saying 4 people say it doesn't work means nothing.... I can find four people that say it does....

the pic you posted again proves nothing except company A claims increases. It is a dyno with POSITIVE increase... it ISNT an F150 and you are just making assumptions as to why they haven't posted dyno sheets. You are spinning this to suit your needs.... but in the end it adds zero credibility to your claims.

again not attacking your personally I just hate when people jump on the "it sucks" or "it is badass" band wagon with nothing to substatiate it..... that's all.

you are probably a good guy and mean well..... no disrespect intended

 

Then let's

1. Re-read what Steve asked for.

2. assume the A/M intake dyno sheet for the 09-10 F150 is identical to the one I posted. It's a stretch, but humor me.

3. assume that all quality (not Ebay el-cheapo models) A/M intakes will have the same basic hp curves as the one above. Pretty safe assumption as you can only do so much with the fixed TB and motion control valves. After all, it is a throttled engine. Plsu K&N is one of the more expensive brands.

Then all you have to do is ask yourself these questions.

1. How was this dyno run actually conducted? Do the conditions mimic real world (open hood? large fans blowing on the engine?)?

2. Will my intake air temperature be higher or lower than stock? If it actually is higher, will this lower the 'real world' hp gains? Might not be much, but we're only working with 11.21 hp to begin with.

3. How often do you drive at 3200 RPM (approximately a 5 hp gain)? How about 4600 RPM? In between?

4. And when you do drive at 3200-4600 RPM, how much gas are you saving? Again, re-read what Steve said/believes:

5. How much more crap am I letting into my engine?

6. What's my $/hp for this mod? Are there other mods that are more beneficial for hp and MPG gains (or at least the potential gains)?

 

I say it's bogus until you do a lot of work to the engine, at least a blower, for one simple reason. Show me an intake that gives a horsepower gain at driving RPM's.

My 03 Altima has an intake. The dyno's from several places showed up to 12hp at 5,000 rpm. That V6 loves to rev and 5k is easy to get too when your redline is 8k rpm.

Now lets move to a truck engine. Show me any dyno from any intake that shows hp at below 3,000 rpm. Why? Because I sure as **** ain't the last off the line but I'm moving ahead and haven't gone beyound 3500 more than a handfull of times.

Intakes and trucks are iffy at best. Combine that with a factory CAI and what the heck is the point when you won't be driving the truck at those speeds and rpm's unless you do more work.

 

So, you're saying that the Tornado doesn't increase mpg and hp?
