There is more surface area on a conical filter and you get more growl. Yes there are cost benefits to keeping stock but that mainly a factor for tighter budgets, a bigger concern in my case is warranty

vs Stillen (long tube) - apples to apples; no other mods or tune. The Gen3 specs a gain of 17 (z1 website) vs 15. Ya its manufacture data but that OK, a stillen 3 guy gonna do other mods and tune anyway. Therefore more cost to get the full benefit of a long tube cai, along with more labor and installation.

Side note on the low end loss conversation. One theory being that larger/longer tubing and better flow actually reduces air velocity at low speeds. I find it interesting that the OP noted the AEM has smaller than typical piping, perhaps by design for this reason. Just some observations; not an attempt to debate as its already been done in other threads. This is more of a product review

Upgraded to the R2C intakes, which have a very similar design to the AEM: 315 whp, 269 wtq.

Attached, just in case it's helpful to someone.

This AEM unit is about as good as a shorty is going to get. The Z1 intake is an easier install with no real flaws for people going for the longer tube CAI option. You'll still make power with the G3, but it's not the answer for people who don't put up with **** craftsmanship.
