no, this is actually a good mod. kind of like my k&n 77 series, it comes with a heat shield. the heat shield prevents hot air from entering the air filter, thus not sucking in hot air. yes the metal tube may conduct some engine heat but it's not enough to actually notice. plus you have a better free flowing pipe over the stock intake.

ok, that is your opinion and you are entitled to it. However, comparing an inake and a tb sapcer is going overboard. On the 03 Exp's 12-14 hp were found via the dyno on that kit so perhaps you should do homework before opening your mouth....

BTW I nor most of the intake manufactures EVER claimed that their intakes alone produced the power; on the 3v 4.6 they are very sensitive to the air inlet track and anything other than a drop in filter results in a CEL and issues.
But of course you already knew that...

I don't care what all the marketing hype says about the open intakes, I have NEVER seen one that could produce a HP increase that could be consistently replicated. Open intakes are worth nothing for mileage or performance.

Now, everyone that has one chime in and tell us about the big HP numbers you have and how your truck feels faster. It must be true, because it would be pretty stupid to spend $200+ on something that does nothing. Why don't you add a TB spacer while you are at it.

dude what are you talking about? an intake that doesn't produce horsepower? don't help your performance or gas mileage? you need to research some more

OK, you keep believing whatever you need to believe to make yourself feel better about blowing the $200. I have seen the dyno numbers, and I have seen the BSFC numbers, and open intakes do not have a measureable gain in either area.

You think those heat shields actually do something? Bwahahahahahahahaaaa! You all got sucked into the marketing hype of these things. Intakes, TB spacers, Tornado, Bosch plugs, Splitfire plugs, blah, blah...they all make these amazing claims of power and mileage increases. If you believe the hype, you would have a 400hp truck that got 40mpg.

Jump off the band wagon. Stop following blindly based on marketing hype. Do you own research. I have done it, I know what the real world results are. You have your opinions, and they are based on hype, not fact. Anyone that thinks an open intake is worth 20+hp deserves to be parted from their money.

12-14 hp? Really. Was that on your dyno or was that in their marketing literature. Hey, Tornado adds more than that based on their marketing hype.

Okay so I have to jump in with my take. You are saying you have done all this research. I would love to see it. I'm not saying its not true I would just like to see it.

I have a AEM intake on my truck and did see a sligh improvement in the higher rpms. Which if you go to there web page and look at their dyno numbers you will see a small improvement.

So lets see your research to back up your statements.

The man the designed the kit has been making CAI's for 5 years, started in the mustang world and has never sold a kit that does not make power. FYI the web site is www.jlttruecoldair.com, look at the dyno sheets to see for yourself. I have used his kits on an 03 Cobra and my 05 Exp and have dyno sheets before and after the install to back the gains up with. Troll on, jr, you are out of your league on this forum...

Troll on!!! You are funny. You are just a sack riding band wagon'er who needs to feel better about the money you spent on something that has absolutely no affect on everyday driving. Dyno sheets produced by those mfgs are so skewed that it isn't even funny. Notice how they NEVER post the conditions under which the dyno runs were made? If you want to show a HP improvement, you change the conditions in the dyno cell. Oh, and the systems that did add power, we are talking like less than 5hp and that is over 5000rpm, and that was in perfect conditions with the vehicle on the dyno. Yeah, that helps a lot in everyday driving. Not to mention that in real world conditions (hood closed, high underhood temps) the IAT of the supposed CAI were so high that it actually took away power. Sitting on a dyno it is very easy to control IAC (hood open, big fans blowing), but in real life IATs can get up over 150* with your CAI. Air that is 50* above ambient is going to take away more power than the CAI will ever add, not to mention that the ECM is going to be pulling a lot of timing advance out and that hurts power even more.

Anything that pulls air from under the hood is NOT a "cold air intake". I don't care what kind of tin shield they give you. All you need to do to see that I am right is to monitor your IAC. Simple. That is something that each of you can do yourself. Don't blindly follow what the vendors say - do a little research yourself. You can confirm EVERYTHING that I say here with a simple performance computer and monitor.

Yeah Greg, I'm well above you junior league guys. I drop down here to the junior league every once in a while to see if there is actually anyone here with a brain. No such luck on this trip.

jeeps&fords,

you need to shut up man, the more you talk the less i can talk because we'll be saying the same things LOL ahhaha . by the way bro you can check out http://www.outlawpower.com for the intake if youd like, and i can hook you up wtih an authorized dealer who sells on ebay for a good deal

my take,

heat shields are complete sh.it. unless you an guarantee a complete seal of the engine compartment from heat its absolutely ignorant to assume theyd do half a damn. more marketing rhetoric and youre soaking it up like a sponge. yes K&N F150, they do design intakes that will reduce your power, its called marketing. heard of the turbo city dual intake?

on the JLT intake. why do you think they sell it with the tuner? it needs it as a compliment otherwise it would be making the same amount of power as any other hot air intake.

as for those who argue about ambient air temps being close to underhood temps, that is the biggest bull in the world. even at 100 degrees ambient wtih my outlaw sucking 105 degree heat its a damn big difference over a K&N sucking 150-60 degree heat. ive run two similar intakes with and without airbox and its enough of a butt difference. if you want empirical, my edge evolution reads the IAT sensor, and id gladly measure underhood temps wtih a laser thermometer when i get back to southern california this august

98 lariet 4x4 also brought up some good points. "is it better to have less air at lower temps or more air at higher temps?" he also brought up "the engine can only take so much air". the motor only does take only so much air and even if you had a 6" open air tube good for 5000000 CFM its not doing crap. only makes good sense to have that certain amount of inducted air to be cold, relative to the engine compartment.

Whatever. I watched both of my vehicles be dyno'ed as well as 2-3 more with data logging during the run. You have your opinion and I have mine. I would not support nor promote a product if I did not see it work eihter via the dyno or SOTP. I took issue with you and your comment that a TB spacer and an intake are equal which ini your opinion are worthless. That is just wrong and I hope your inaccurate analysis does not inlflunce people wrongly. I am out...

SoCal, thanks for the link. You had mentioned them in another post and I wanted to check them out. That looks like a nice system. I'm actually working on a ram-air system for mine - I want to pick up high pressure air from behind the grill and duct it to the air box. I'll post pics as soon as I get it done.

This has been talked-about, tested, re-tested, shot dead, kicked, and buried many times over the years.

Here's just one thread, use the search for "underhood air temp" on this site.
https://www.f150online.com/forums/sh...rhood+air+temp

When the vehicle isn't moving, temps rose. When you start moving, or even when your e-fans kick on, temps drop. When you are at speed, temps are close to ambient, but still slightly higher, from 20 degrees to less than that. Yes, this robs a bit of power. But it's not like a 100-degree variance.

My Procharger has an open element, but also an intercooler. IATs at speed are consistently about 15 degree above ambient...and the 2-core intercooler isn't that efficient.

with all your little dyno numbers and your temperature testing, all i can say is when i bolted on my k&n intake i saw a big difference in performance over just having my gibson exhaust. so what do you have to say about that jeeps&fords?

Those sound like really high numbers for an intake and tuner. What vehicle did you get these numbers on?

I know it hurts people's feelings to get ripped off, but this guy's got a point.

Just for fun, I went and played with my truck's air filter after my engine warmed up. According to my evolution, my iat temps go to almost 170* with the air filter box unlatched, and it makes the truck slower in the 0-60 and the 1/4 mile. The cooler air is a lot more dense, therefore you get more O2 molecules in every cubic foot of air, so colder air is the best way to gain power. The engine only pulls in a certian ammount of air. You can't really change that ammount by much unless you go nitrous or super/turbocharger, or cool the air down.
