wow thats disappointing haha i still want it for looks and im sure it might have a little change hopefully...which one would you get though?

 

I'll give you my honest impressions of my aFe CAI.

I love the sound, it's mainly just sound and that's it.

I don't like the concept of oil filters getting on my MAF sensor so I went with the Dry Series. No recharge kit needed either.

I hear bad things about gunk buildup from K&N so i left them alone.

aFe is the same company that makes the TRD CAI and the aFe version uses the same instructions and parts to install (I used TRD CAI instructions to install my aFe in about an hour).

Didn't improve MPG at all, didn't really feel any performance, but sound is awesome. You only hear it when engine under load. Cruising at hwy speeds at 2000 rpm with no load in bed or trailer and it's silent, but when you hit the gas you hear it roar.

All in all, $300 would have been better spent on my Radio head unit, or airbags for towing, but I'm still pleased with the purchase, I love that sound.

 

thanks a lot this really helps... i might not be going with k&n anymore

 

I had a K&N and it did sound great but I hated having to oil the filter, always a big mess.

 

Cut a hole in your stock airbox. It will make same sound as CAI and will save you $300...lol

 

Thats great if you want to suck in hot air from your engine...

plus the 4.0 airboxes dont look anything like that.

 

Is aFe the only dry filters out there? I picked mine specifically for that reason but I don't recall if others have it. I agree tho, the drop in filter is also a great choice, just don't get the sound.

**NOTE** If you tow a lot or go uphill all the time you might not like the droning with a CAI. I tow occassionally and deal with it, if I towed constantly I might just go with the drop in with the stock intake.

 

I have just installed a second generation TRD CAI and from my experience there's no doubt that engine performance is improved. I also have the TRD cat-back exhaust which seems to work very well with the CAI. In gears 3-4-5 my truck really romps like never before.
As a firm believer in Toyota products, I have a hard time believing they would design a product that does not perform well.
Is anyone happy with a 2nd gen TRD CAI?

 

Has Toyota engineering made the determination that the new CAI causes lean running? Wouldn't lean running cause valve problems and possibly a really expensive TSB for Toyota to remedy?

 

Well, I tend to believe that products that can result in great expense to the oem to resolve, would be tested to avoid that happening. I realize that bad products do get on the market.
Also, a lot of misinformation gets perpetuated without the who,what,when,where and how being known.
Thanks for your response

 

Hello Steve,

Thank you for contacting AEM Induction Systems. We do make performance parts for some automotive manufacturers but I don't believe TRD is one of them. Most intake systems develop power in two ways - less restriction and a slightly leaner air/fuel ratio. Running slightly leaner develops more power and burns a little hotter and extremely lean AFRs can burn your intake valves, but when performance intake kits are developed, the AFRs are (should be) tracked and a kit will not be developed if the AFRs are pushed beyond what is safe for the motor. I can’t speak for TRD or our competitors, but AEM’s intakes are designed to work within the factory programming parameters of your EMS and to safely develop more power from your motor.

If you have any questions, please feel free to reply to this email or call our customer service department at 1-800-992-3000 and we will be happy to assist you. Thank you for writing.

27000 miles on my AEM CAI, I love it! Yes no better mpg gain, but boy 3k rpms an above you can hear it roar! No problems, fits nice, sounds good! CAI, lift kit, air bags an a stereo. Only mods done to my truck, and in that order!

 

1st generation trd cai, might be a little hard to find, but definitely the best IMO
