well guys i dont know about yall, but after i installed the tb spacer and intake i saw an improvment on gass milage and throttle responce. all the cold air does is bring more air into the engine, rather than the factory with is an small 2 inch hole. i am not a scientist but air will flow better through a 4 inch tube rather than a small hole which opens to the filter then back to a small hole on factory setup. also installed high flow exhaust and headers this weekend. and the point on the tb spacer is that i spirals the air into the intake similer to a tornado and it does work. i am turning 35 inch tires and every little bit helps.

 

For one thing most CAI setups suck in hot underhood air. They also use oiled filters that no not filter as much dirt out of the air and can foul the MAF and other electronic sensors in the intake tube.

I agree with what was stated about the amount of air flow for the RPM. The stock air box is just fine.

Even if the CAI does give you 5 hp, it will be a wide open throttle and you will not notice it.

All I know is I have had them before and would never buy one again. The quality is not that great anyway.

 

so... thats two of us that have seen improvement...... kinda shooting a hole in your "junk" theory huh? now ill admit i didnt notice much if any throttle response improvement, but definately with mine anyway, you simply cannot ignore 3 mpgs. if the new filter and spacer didnt do it, then what did? cause it sure as hell wasnt my right foot.

 

Ford has spent billions trying to get truck and car milage gains. If you could get 1 MPG improvement it would be a big deal to FORD. To get 3 MPG out of 15 would be 20% improvement. That would be worth a fortune to FORD. Again, the type of gasoline (ethanol content), ambient temps, summer or winter blend gas, and your right foot atre 90% of the improvements or changes in gas consumption. The nice thing about Americas is its your money and you can spend it anyway you want. Just dont want those that have not bought yet to be disapointed when it makes no different on their truck.

 

Why are these companies still in business? I liked that one. Ummmm...how about advertising and a gullible public How about a group that wants to make improvents to their vehicles but relly has no understanding of the actual mechanics involved to do so. Or the goup that wants to pop the hood and show thier buddies the mods they made, and how cool they look. Better yet, hop in and floor it....ooooohhhh the sound. Sounds faster, looks faster and somebody in an advertisement told you it would make more power. That is exactly how they stay in business and make billions.

I love the notion that the spacer spirals the air like a tornado. And we are supposed to buy into the fact that this tornado remains intact around the bends and as air flows down individual intake runners even though there are valves opening and closing constantly disrupting the flow. THAT is an amazing concept. Not based in any fact but is sure sounds cool in an ad. Better mixing of the air and fuel might help but since we are talking about port fuel injected vehicles here, that is dependant on the injector spray pattern, not the tornado in the intake runner

Glad it worked for you guys. I wouldn't spend my money on these things without some proof beyond taking a few guys word for it on the internet.

As for the small air inlet. I think I posted how to cure that. Remove the 2" horn, replace it with a 3" tube. Costs under $10, feeds more cold air to the stock paper filter.

The problem with my intake and exhaust mods for most of the young guys on this forum is, they might work better but they don't look as cool. I just happen to prefer to decorate my house, not my vehicle. My intake mod looks stock but flows a little better than stock. My muffler replacement flows better, sounds better but looks stock. I fit big tires without doing a big lift, works great, not as showy though. The intake mods in question are defiantely showy, that is why they sell. Just depends on what you want. Just dont try and say your showy mods actually function until we see some dyno results.

 

the first thing im gonna do on my f150 is a gotts and see where that leads me. im all about saving a buck, and 10 bucks is a hell of a lot better than 160 and if i could have done something simmilar to the ranger you can bet your *** i woulda. but i agree with what your saying about the 'tornado' being disrupted. i dont understand it. but i also did notice that after adding the spacer my coolant ran consitantly lower temps than it had without it. i cant explain this except for maybe adding i big chunk of aluminum could reduce engine temp. maybe this resulted in the better mileage?

 

Just an FYI. I did the Gotts mod and didn't notice any difference. I didn't really expect anything but I do like the idea of removing the restriction the factory placed there. The rest of the intake tract looked pretty good to me. The muffler I did was for the same reason. A little extra airflow couldn't hurt when most of my driving is between 6000 and 10,000 ft of altitude.

 

You see, the problem with your argument is that you can get that kind of economy and performance with a properly tuned stock system. It is not uncommon for people to get 19 or 20 mpg with the stock setup. It is however possible that your MAf has gotten messed up by the filter leaning your truck out enough to save a little fuel, but this is at the cost of performance, and it only leans it out during acceleration.

The numbers don't lie, but the sequence of things that results in those numbers can be very misleading.

 

here is the stock snorkel. . leave it off and butt a 3 inch PVC coupling to your fender well. go to the second photo. You will get a slightly more noisec, but not really better MPG

All I know is we have had a couple of the so called CAI intakes over the years and always saw a loss in mpg. I always got rid of them and mpg went back up a little.

The reason these companies are still in business is that they have good marketing teams and their filters are good for very high horsepower race motors. On those motors the more dirt that is allowed in is not that significant because they do not try to get thousands of mile out of an engine. They tear them down every few races. Also, the small power gain is a percentage. So a small increase on a stock motor, will be a bigger increase on a high powered one.

 

I have a friend that is the gullible public. He will try anything and spend anything that sounds like a good deal to him. He got into selling fuel catylist a few years ago. He swore up and down that it worked and would give me up to 5 mpg more. I asked him if he was using it and he said yes but it was not working yet. It takes a while. After about 4 months he quit selling it because he actually got worse mileage.

To my point, he tried the CAI also on a car. The same promises of increased fuel mileage. This time I helped him because I was curious but not willing to spend the money. I forget what he paid but is was around $300 as I recall. He improved his mileage by .25 after one month of driving. I hardly think that was worth the price tag.

In my expirence properly inflated tires, keeping your foot out of it, and driving like a sane person will give you the best mileage you can get. Other than higher octane fuels.

Thats my nickel worth anyway.

With competition so tight with all the pickup makers if one of them made a better mileage truck they would sell far more than anyone else. I agree that any of them would pay huge money if somone developed a product that actually worked.

 

Yep-I agree completely. This works perfectly,and cost about $5:

 

If you do an online search for “air filter test” there is a lot of very good information. IMHO, the CAI units are NOT WORTH THE $$! Unless you are talking about a system that was specifically designed for a specific application there are very little hp/tq gains actually achieved in a street use vehicle and there are very few docs that these mfg’s can produce that actually show an increase in hp/tq in the power-band range of a relatively stock street vehicle.

I would avoid oil impregnated filters. While they have their purpose in off-road applications, Ford/GM/Dodge all have “watch-out” bulletins where the oil has contaminated intake sensors. - they even have a training video for the tech's on this (flatratetech.com) .

If you look at the flow data, WIX HP filters flow 98+% of K&N and have a much smoother flow post filter plus excellent filtering, for a fraction of the price! The OE’s have an excellent air intake system and if you read the supposid HP/TQ gains from the sftermarket, you will realize the gains are within 5% which is also within the dyno varience.

You can use a WIX OEM HP replacement filter in the OEM plastic manifold box and either remove the plastic tube and replace it with a piece of pipe/hose, etc or remove the tube completely and replace the tube by building an air ram type intake into the air box manifold (where the pipe use to attach)- make sure ti terminates above the fan shroud to avoid water intake or fan induced pulsations.

 

no offense guys but the 10 dollar riggin yall have done is not my cup of tea. i dont want to enter a car show and have bailing wire and duct tape hanging off my engine, i didnt mind spending the 50 dollars i paid for mine, not because it helps with gas mileage, but because it looks alot better than some home made setup. as for all your setups weither it be CAI ot tb spacer or anything, they have to atleast do somthing or else people would call false advertisment.

 

If you're buying for bling,then these products are fine. If they're being purchased for a power or efficiency gain-they're a joke.
