Silent cold air intake upgrade
I have been looking inot the different options in regards to air intake upgardes but my major requirement is for an upgrade that will not be very noisy and offer performance improvement.
Now, I know that RX8's stock intake is very well designed and I've read that most upgrades will not provide significant improvement however, most of the articles I've read are rather old and I would like to ask if there are any news in regards to this.
So, is there any upgrade that will provide significant performance improvement with no significant or at least minimal noise increase?
Anyone tried this one: ?

Your suggestions are apreciated but please remember that I don't want to be noisy.

Then, will it offer significant improvement?

I remember there was another option with a cone-type filter in enclosure that replaces stock (to keep noise down) but I don't remember if it was K&N or other brand. I remember it was the best option to replace stock with major improvement.

I am thinking about taking the Racing Beat REVi Intake upgrade but I am wondering if the benefit in performance will be significant. Since the stock intake is very well designed, does this upgrade offer significant improvement? Is it worth its money?

I could accept a slide increase in noise at about 20-25%. Will that be in this range or louder? and will it offer enough performance improvement, worth to sacrifice the cost o fnoise?

I zoom therefore I am.
intakes offer little if any improvement over stock, most lose power on the dyno. You change the intake for the sound or if you plan on going FI in the future.

Well, I guess you are right. If that's the case, I'm staying with stock and saving some money.

Keeping the stock intake is probably the best route. If anything then maybe replacing the VFAD and the sock tube with the Racing Beat duct makes the most sense, provided you fabricate a coupler that achieves an airtight seal between the duct and the stock intake box.
I remember someone used a hacked-up VFAD assembly to do that.

that said, there is a dyno comparison of the Injen CAI and the Racing Beat Revi CAI and the Revi more 10 more WHP than the Injen but there was not a dyno graph of a run with the stock intake so you can't really say the revi gained HP over stock, it might have just recouped HP lost by the Ijen in the first place.

This is what I did, I have noticed lower IAT's but I don't have any definitive data nor have I taken the time to do any testing. I made this using the factory intake duct off of a 2010 GT auto and a generic autozone intake tube that fit in the factory end very, very snug. The diameter of the 2010 Auto tube is much larger than the 6 speed VFAD tube.
