Which aFe intake is better, Stage 1 or Stage 2?

Recently noticed that aFe now offers two intakes for the E46 330, the traditional "Magnum Force" Stage 1, and the newer Stage 2. Does anyone know which is better?

Stage I, List price $395:
Uses metal velocity stack to direct airflow to MAF
Top seals with screwed on aluminum cover.
Cone filter appears to have open end.
Separate models for 325/328 and 330 (3.0" vs. 3.5" MAF coupling)
aFe claims up to +20HP

Stage II, List price about $300:
Uses plastic elbow tube to direct airflow to MAF
No cover; top seals against hood with rubber seal
Cone filter appears to have closed end
One model for all E46 non-M (includes 3.5 to 3.0" adapter)
aFe claims up to +6HP

Has anyone here tried the Stage II? Does anyone know if the Stage I uses a larger cone filter that might offer more airflow?

It depends what your definition of "better" is. If you are looking for performance, the stage I system is the way to go. If you are looking for an affordable solution that still free's up some performance, the stage II would be the way to go. I would personally recommend getting the stage I. It is only a bit more, but you get much more performance. You can choose either the Dry or Oiled filter. I suggest getting the Dry, unless you don't mind re-oiling the filter after cleaning. We sell both stages. Let me know if you have any questions.

JFYI, NO intake makes 20+ HP on a M54 N/A motor....NEVER.

3-5 WHP, sure.

With all the money your gonna save, I drink Coors Lt.



Good luck.

Thanks, everyone. I did see Rob recommending that Cosmo racing intake earlier and have thought about it, though I'm not eager to relocate my Xenon transformers. I knew no intake is going to provide +20 HP, but was wondering if the higher claim for the Stage I meant that it made more power, for example would the aFe Stage 2 give me +6HP and the Stage 1 would give me +8HP. If that is the case, is it because the Stage 1 has a bigger filter, velocity stack, or better hot air exclusion?

Being in California, I also noticed the Stage 1, which has been around a long time, has the CARB # while the Stage 2 does not (at least not yet).
