Another AFE CAI Thread - Where's My HP?

[Broncoblair]

So today per forum guidance, I installed a stage 2 AFE CAI. The only thing I've noticed so far is the sound. Other than that, honestly, I think I have less power.

I can tap the accelerator a few times and hear the air intake catching up. Slower than I am accelerating. Seems like the old air filter was fairly even with an accelerator tap. Also doesn't seem to have given me much hp. I went to the same stop sign yesterday and floored it. Got a little screech out the tires. No screech today. The engine was definitely louder and rattled my cab. Was awesome. But didn't feel like the car had improved performance wise.

How important is the seal to the side where the old air intake drew from?

I did the best I could with the baffle provided to wrap around the enclosure to ensure a tight seal. But after a spin it had come half undone. I may have to tape it on.


I know a lot of guys say to get the computer aligned for the extra air to compensate with more fuel intake. Is that the key to getting more power out of these? I want it believe it's got more juice but I can't let my ears be the judge, as awesome as it sounds.

The idle sounds fine. Right at 600. No sputters. It doesn't appear to be lean. Gas mileage seems to be about the same..


Any tips appreciated! I'm gritting 5100's put on next week and trying to track down some FJ springs. Thanks in advance!

[MENTION=104720]Broncoblair[/MENTION] theres been a bunch of threads discussing how the CAI's are usually nothing more than sound, especially if you don't re map the ECU. URD sells something called the MAF calibrator, and it makes the adjustments necessary to get the most out of your CAI. That being said, its possible that you did lose power by installing it. have you disconnected the negative battery cable so that the MAF relearns the A-F ratio? i have the K&N cold air intake and until i did that, it felt sluggish, didn't idle right, and the RPM would bounce around when i was driving.

From what I have read in the other threads over the years the AFE Intake was a nice acoustic and aesthetic mod. But very few people indicated power gains. As mentioned in the other post URD makes a MAF calibrator which may help. But once you buy the intake + MAF devise you paying a lot of $$ for not much HP.

But if you like the look & sound be happy.

try the battery disconnect &/or buy the urd cal. & hope for better throttle response, but dont expect the 10-20+ hp gain a cai claims.

Lol at this thread. Cold air intake manufacturers are the biggest sellers of snake oil ever....and guess what people like you bite. You would be correct, you gained nothing but sound.

(Ps I have the TRD ONE on mine made by AFE. But it came when I bought 4Runner)
