OK, I'll buy that.
I'd like to see the numbers. I'm curious what difference it made over the rpm range. I assume you have before and after numbers?
My STi was tuned at Cobb. My tuner was weary of even using an intake at all, because a lot of them put out there for sale are bogus/bs, and really do nothing. The AEM is a well engineered product. It was added last then tuned immediately. Dyno operator said it added extra HP/TQ over normal stage 2, could see it on the MAF and showed me.
How much of a difference on the RL G2, no idea, but it will flow more air compared to stock. Without a tune, will probably add small bit of power, and lead to 1-2 MPG difference. Tuned, different story, that's where you can really take advantage, by altering AFR's. But as of today we don't have a way to do that. Myself, I'd change the intake to the AEM product for maintenance reasons alone. It's a dry filter, so all you have to do is clean it every now and again, like say during oil changes. Simple process. Open it up, shake the crap out of it, reinstall. Maintenance reasons alone it's worth it, but won't be worth it to everyone, especially the anti-aftermarket crowd. Normally aspirated engines are much harder to make power gains so without changing out headers or opening the engine up, all you can do is increase airflow (via CAI) into the engine and out (via aftermarket exhaust with high flow cat).
This is just the first worthwhile engine mod I've seen. I wouldn't buy the AEM until we start seeing exhausts available. I'm partial to Borla on that front but it'll be 6 months to see what comes out.
