not in my opinion.

There's really no hidden HP waiting to be unleashed in an FJ, unlike other vehicles.

save your money for something else...

 

All I've heard about CAI on the FJ is that they really just make it louder. Not much else. If you do get one, I'm pretty sure you can install it yourself with very few tools.

 

The stock CAI is pretty decent in the FJ - and it's not exactly a racecar...
Spend your money on stickers instead - there's 5 HP in each sticker.

 

Now that's damn funny!

 

I bought my trd intake years ago, before they changed the design. It is essentially the same as the AFE cai, except the airbox has only one opening that gets air from the stock inner fender well location, which happens to connect directly to my safari snorkel, giving me a sealed airbox and fully functioning snorkel. This is why I bought the trd. All other intakes at that time had an extra opening in the airbox I would have had to plug. The trd cai, was, and may still be, made by AFE. The only difference was, the filter cover plate says TRD or AFE.

The AFE intake claims 13hp and 21ft/lbs increase
Their dyno sheet shows 10hp and 10ft/lbs max gain at the wheels. the biggest torque gain being at 3600rpm

Can you feel the gain, yes, if you have no other mods that slow the FJ down, like bigger tires, lift, skids, bumpers, etc.

This is part of my interest, and point behind wanting one.

I somewhat get the others saying the FJ is not a sports car or what not, but more power is more power. If it adds HP and torque, I want it.

I have 285/70/17s with a full size spare on the back. Those have surely added some weight. I also very often make trips from the valley up to northern and northeastern AZ. I'm regularly going through/up steep mountain ranges on those trips. Gaining as much as 8000 feet in elevation from start to finish in some cases. Added power and torque certainly can't hurt.

I'm just looking for confirmed results, like the poster above stated, and curious if there are any drawbacks.

 

Buy you a K&N filter and call it a day.

 

There really aren't any cheap mods that affect the performance of the FJ in a meaningful way. If you like how the aftermarket intake/exhaust/headers sound, then you should get them. But the only real way to increase the power is with forced induction. You can also improve acceleration by changing the final gear ratio. However, forced induction or gears are vastly more expensive than an intake.

THIS!!! :clap:

 

i bought the Airaid Cold Air Intake and noticed a little differences but it sounds great when you step on it

Cold Air Intake, no ... TRD Supercharger, yes (on an 07-09) ...
:smile

 

I once parked next to someone with a CAI and my FJ gained 35hp instantly. :wink> I never had a CAI, but I did have a K&N filter that I used off and on and can say that I never noticed any difference with it. The only thing that made a real difference was when I went to a V8 and that was a big one.

From this ^^^^ expect to gain about 20 HP from an exhaust and CAI combo. Them guys with Tacos know their stuff when it comes to street performance. $750 for 20 HP (maybe) is not much of a gain IMO. But, I like the better sound that comes with both (some don't) and I like the bigger and easily serviceable filter, not to mention better sealed intake. If you want true performance you need boost.

This is as good as it gets without boost, and you only gain about 50 HP and 50 TQ's for $3k.

The problem with posting dyno charts is that all vehicles and all dynos will put out different numbers. When you are talking about very small gains, it's just noise unless the tests were done under very controlled conditions. I've dyno'd my supercharged FJ on a dyno that is certified and monitored by the state to test diesel emissions in Colorado. The results were laughably low compared to some of the dyno charts I've seen. Comparing dyno charts from different vehicles on different dynos is completely pointless. I probably could have driven my truck to a dyno across town and "gained" 20 horsepower.

URD makes awesome stuff and I have no doubt that these are legitimate gains. Seems like an amazing package. But, yeah, if you are spending that kind of money, and fiddling with the ECU (where I suspect a lot of the gains are coming from), you might as well go forced induction and add an intake/exhaust.

 

Get the sprint booster before the cai, that you will feel a difference. Then get the cai along with the urd maf calibrator, then gears. If that's not enough then super charger.

You do realize a sprint booster adds no HP right? It just turns up the sensitivity of the throttle making it feel more responsive or quicker...

 

I have the CAI and the TRD exhaust. Installed shortly after purchase. Figured the very least I would have done would have been a K&N which is ~$60 so 'real' cost to me was ~$300. Would I do it again after 56k miles? Absolutely. Plan on keeping the FJ forever, so $300 is insignificant.

 

No hp gain, but it does accelerate faster. How can you give an opinion on a product if you haven't tried it yourself?

I do research before I buy anything. I go off of what I read and what others have experienced. Nothing I said is opinion either...

 

The link you posted he states he's never used one...opinions are like assholes everyone has one [emoji3]

The sprint booster by far was the best bang for the buck in the "more fun to drive" department. It makes the FJ feel like it has a hell of a lot more pep. But I bought it because it made *me* smile more when I hit the skinny pedal, not to impress other drivers with actual speed.

The CAI/Snorkel combo I have may possibly give me more gain, I can't tell since I did many things all at once... but when I'm wide open throttle I can hear it, and it puts a smile on my face. That smile to me was also worth the price I paid.

 

You can't really complain about the FJ feeling sluggish until you have 35's, stock gears, and a couple hundred pounds of steel attached to it.:grin

That being said, I did feel like my FJ had a bit more pep after installing a snorkel and K&N filter. I am also about 90% sure that was psychological due to my love of modding and the hit to the wallet.

The only two ways I can think of to really improve power on this engine are either a TRD or URD supercharger, and that is slightly more expensive than a CAI.

 

If you are looking for more power for 8000+ft elevation a cai isnt going to do crap. To effectively and efficiently get more power at those altitudes your going to need to take your skit off and supercharger it.... Or turbo! Which is my personal preference for forced induction

I live at 8000ft and have a supercharger, gears, CAI, exhaust, etc. If I had to do it all over again, I definitely would have gone with a small, fast spooling turbo. Turbos are king at high altitude.

 

Some of our ww2 fighters had dual power adders, a super for low altitude speed and a turbo to out climb the adversaries, helped us win the euro theater! Giddy Up!

 

Back to the CAI, I had one on my 2007 TRDSE.
The newer Stock VVT engines have a straighter path from the air box to the induction camber, so IMHO, the need for a CAI is less on the newer engines.
That said, they are fun to jack, but check the poly rubber connector tubes for wear.
They begin to deteriorate from the oils and heat, mine got a hole on the underside but luckily I caught it in time before my engine got sanded.
So check the underside of those pretty red or blue poly tubes if you bite for one.....gm
