Are aftermarket intakes worth it?

I love it as well. Do you notice that the torque dip is more noticeable? since there's more torque in low end and high end.

I know i will love it so much more when i get my headerback and stage 2 tune.

I def did, mines oiled but still. Especially around like 2k rpm

Your torque dip starts at 2k rpm?! That would be a bummer for daily driving

I was experimenting. And 2k to about 4k or so it seems... Oh we'll haha

I'll have a another guy drive mine to see what he thinks.

How did you experiment? I have perrin pulley as well. my torque dip starts at 4k - 5.5k rpm. From 2k to 3.5k is a good increase in torque from stock, and from 5.5k to redline is a surge of torque thats feels nearly like VTEC

I did diff types of launches at diff rpm, kinda hard to explain but I hear ya after the 5.5k to red line.
Ya the pulley kit def made up for it though.

But funny thing is, car makes more sound than what it's running or going lol

On the 1st and 2nd gear, I do feel the car gave extra force after the aFe intakes installed. That is true, on the low end it help the torque.

Yeah i know thats why the torque dip is more noticeable now because low end torque is more before the torque dip. So when your from 2.5 - 4k, your like , then when it reaches 4k - 5.5k you go then when you reach 5.5k and you feel that surge of torque you go

What pulley do you have?

I've posted my thoughts earlier on intakes, but I installed the TRD airbox and couldn't be happier. The issue is drivability. The TRD gave me a much improved lower end compared to the original equipment. I can conceive of some horsepower gains from tuned systems at higher RPM's, but I'm pretty sure the gains are relatively minor percentage wise, and likely to result in a peakier throttle response. For my purposes, getting a nice steady pull from launch to about 6 grand makes the car much more drivable and enjoyable. Don't get hung up on small percentage gains.

I purchased my AFE intake from another guy at a local BRZ/86 meet for $250 brand new. Installed it and it gives noticeably more torque only in low end and high end. Because of this, the torque dip is more noticeable.

A TRD air box costs about $600 here in Australia. And it adds similar gains to the AFE intake. I think the AFE is the better buy per dollar. The best buy per dollar is the K&N filter.

I have been running the TRD intake for about two weeks now.

I only have butt dyno numbers but here is my opinion.

My car pulls harder in low and high rpms than before (at least enough for me to notice a difference). It seems like the torque dip is worse now than before. I really feel the dip in torque at about 3.5k-4k and then the engine picks up again around 4.5k and comes in like gang busters around 5k rpm.

I love the sound the intake makes and the fact that the stupid sound tube is gone more than anything else.
