Anyone with any CAI / AEM intake have seen a noticeable increased MPG while driving normally?

blkaspec

probably, but i spend too much time listening the the engine roar to see any savings

EnvisionTL

decrease mileage for me.... I like to hear it roar so my foot is on the gas more

I've never noticed any improvement. Theoretically it is supposed to increase your gas mileage, but I can't say either way. I say it's a wash, and I don't know ANYONE who got a CAI for the improved gas mileage. CAI's are for performance and the accompanying sound for those who are into that.

just installed mine this wkend, increased from 24 to 26...

You usually get around a 2-3 MPG increase, but then you lose that extra MPG by wanting to drive the car harder.

erick3

agreed...my foot's made out of lead...lol

Be-in my TL

What kind of CAIs are you guys using? Any insight on which I should get. I really would love to hear the car more, but at the sametime would LOVE to save gas.

visuelz

I've notice that in the TLs, the CAI is a lot harder to hear. In my TSX, I notice it as soon as I step on the gas. This may be due to 4 cylinders working harder than V6. I recommend Injen because everything is a perfect fit.

omnuts

the two common brand around here is AEM and Fujita.. check the performance sect.. for differ... I'm running Fujita..

Distorted Reality

I noticed maybe and I say maybe 2-3 better mpg. But reason being I drive with a heavy foot. I have the fujita and I love it def. would recommend it and fits like a charm.

18 -> 21-22 city
28-> 30-31 hwy

My CAI is a lil diff because it doesn't make any noise, but they all have the same purpose. Colder less restricted airflow.

blazinginder

are there any warranty conflicts that are possible by having a CAI? also how much does it cost for the parts and install?

DrMooCow

CAI will void the warranty only if the dealer can prove it was what caused it.

The reason why I'm asking you guys if there's a noticeable MPG increase is due to the gas prices. I'm not whining yet but I will be when it hits $4.50 a gallon for the lowest grade. Right now I'm paying $3.68 for the highest grade so if the low grade hits $4.50, it means I'll be paying nearly 5 for premium grade.

I'm already driving 65 on the highway and it makes a huge ass difference. If you don't believe me, try it yourself.

If the filter falls off and you ingest a chipmunk into your motor, then no, it won't be covered under warranty.

ballerjai

You're highest grade is 3.68? Mine is already 4.39 (San Francisco, CA)! As for your claim about voiding warranty, it's not true. I thought the same, "Magnuson Moss Act." Search the forums, their was high debate, and well basically your driver manual says you can't do any mods. They will void you for the littlest things. If something did really happen, just swap your stock intake back on. Anyways, I'm rambling, CAI doesn't save gas for me I'm getting 14mpg, I love the sound too much.

I hate cars

If a CAI could get 2-4mpg extra, every TL would come with one from the factory. 2-4mpg is huge for a manufacturer.


Please tell me how less intake restriction= better mileage. More power, yes. Better mileage, no. Exhaust is the only mod that will increase both power and mileage.

The only way this will make more power is if the car is detonating already and the cooler air helps prevent this.

spiike

Probably because like the person here a couple months ago that decided to drive in the rain, injest water, and hydrolocked his engine.

Even lexus is offering cold air setups (looks like the icebox design and is quite ugly) so yes the auto companies know it increases performance powerwise and fuel efficiency wise, but probably think the benefits are too marginal for the mass public.

There was a monthly news bulletin about the CAI and the TL from Acura, that explictly stated: although it increases power, increased particle injestion into the motor was a high risk. So Acura does awknowledge the benefits of the CAI, but the risks of engine deterioration outweigh the benefits. This statement is backed up by the April 05 news bulletin I linked below.

I hate cars, you of all people should know that cars are not manufactured to their peak performance especially with your awesome spitfire engine. It's a balance for the common public and performance. Also better power for the same unit of gas = less gas to make the car move. So better power in this case = better gas milage.

odessa

Why not divert air from the A/C and get the cold air that way?

I hate cars

They're definately not manufactured for peak performance but a few mpg extra are really big for an auto manufacturer.

The engine itself is throttled (by the throttlebody). Say you're doing a steady 70mph down the freeway. You add a CAI on the fly and take some restriction away from the intake tract. The car now accelerates (burning more fuel to match the air). You back off the throttle to compensate to maintain your 70mph speed. You're still flowing the same amount of air and burning the same amount of fuel as before the CAI with slightly less throttle opening. Nothing changes as far as fuel economy. It will always take a certain amount of air and fuel to make a certain amount of hp.

Exhaust on the other hand will give you power and economy. The engine has to pump exhaust out which takes energy. Free up the exhaust and it can pump easier for the same amount of fuel burned which means both power and mileage.

So basically what I'm saying is if you restrict the intake side you lose power but you maintain the stoich A/F so mileage remains the same.

Restrict the exhaust and the engine has to work harder to pump it out which will decrease mileage.

The only mileage gains from a CAI could come from the computer advancing timing when it sees the colder charge air, nothing else.

F5 Fujita CAI
...honestly, all cai are the same; i got my fujita because no one else had it...but then again looking back now I probably would have preferred to have gotten an aem cai...for the comfort of "support" since everyone has one...

erick3

is that a serious question? lol

Because then when it's hot we'd be screwed!

BEAR-AvHistory

And you have to wonder about how cool that really is since the guys who responded to my question said the CAI system gets hot to the touch.

Hot tubing will transfer heat to the incoming air.

I hate cars

That's another good point. I think these companies are more interested in looks than performance. Ideally, a CAI would have rubber or plastic pipes but not many people would buy them if they weren't pretty. You could out do the big companies by shopping in the sewer plumbing section of Home Depot for $20 lol.

The Starbuck

Well according to the AEM website, the only thing you can get for an 2008 is the shit Scion. Is there a problem with the website?

don5504

Nope site runs as it should. the problem is with the web master or who ever runs the site. You know its all 00000011111010101010101 so blame the guy who is in charge of that.

D

The Starbuck

According to the spec sheets you can't buy an AEM CAI for a 3rd Gen TL or S. Which I find that very hard to believe. So how the hell do I find one that I know that will work for my 08 Type-S??

The Starbuck

And if I look at Fujita's website....the latest car year they have on there is an 06 for Acura. WTF dude? Do they not update their shit or what?

The Starbuck

Ha...even Nopi doesn't even have a 2008 Acura listed on their website. Are you kidding me? We are almost to May, 5 months in 2008 and nobody has shit listed. WOW!!

Be-in my TL

Hey, Starbuck, tell me which one you come up with. =)

Keep us updated, I'm thinking about doing it for my 07 Type-S as well... 8,000 miles... considering Seafoam already haha

She gets 23 MPG at roughly. avg 27 MPH

The Starbuck

Will do....

Just checked K&N...get this....they don't make a CAI for an Acura 08 TL Type-S, but they make it for the damn Ford Fusion? Are you kidding me?

BEAR-AvHistory

.
There was no home depot then but its exactly what we did in the 60-70's. You took the inner two headlights of a 4 headlight system out & put 5 inch plastic flex tubing back to a pair of sheet metal snouts brazed to matching holes in the outer air cleaner case. This gave you filtered cold air with a slight ram effect at speed.

Olds factoryized it in the 442 ram air W-30? package with plastic scoops under the front bumper around 1967.


As for performance gains most are so small with modern systems the vendors count on the placebo effect to make the troops think the really got something out of the modification.

TeknoKing

so wait, am I missing something???...

There is not cold air intake to install on 08 TLS? Huh?

I dropped in K&N filter, but there is no difference...

The Starbuck

Yes. According to the AEM, K&N, and Nopi sites they do not have anything listed for a 2008 car or even an Acura TL or Type-S. Check them out yourself. Pretty bad if you ask me.

MWalsh9152

wouldnt the 07 CAI be the same thing?

jeff442

Getting a CAI seems like a no brainer, but my my car doesn't go in a garage and is out in the elements. So your telling me I can't drive (or park) in a downpour if I have a CAI installed?

I hate cars

You can drive in a downpour all you want. Just don't hit any big puddles that would bury the filter in water. You have to really bury it to hydrolock the motor. Even if half the filter is submerged you probably won't suck any water through the motor.

You guys should look at the Amsoil filters. They flow as well as a K&N, filter many, many times better than even the OEM paper filter, don't require oil, and are washable. K&N and all of the others are outdated old technology. The best thing is the Amsoil filters cost about the same. There is absolutely no reason to ever buy a K&N again.

erick3

jeez...obvious but i NEVER thought about that...i figured since the air's rushing in so quickly...it wouldn't have a chance to really heat up?...whoops...haha

visuelz

I don't believe that the hot tubing will cause the incoming air to be hot either.

I agree with you that the incoming air would be too fast for any significant difference in temperature of air.

Another reason why it shouldn't get hot is because the tube has insulation between the outside metal and the inside metal.
