Air intake mods with higher elevation?

[stearnman]

A question I've been thinking about for a while now since I started reading the forums here. What would be the best air intake modifications to do at elevations of 3000+ to 6000 ft above sea-level?

Just Stock?
Open lid with K&N "box" filter?
SLP Cold Air Induction type, with K&N "cone" filters?
Vortex Ram-air style?

No Corvette yet here, but it's a question I've been pondering over and have not seen any articles on yet (minimal searching though).

Thanks for the input in advance!

I know where your coming from.

they would probably all help over a stock setup but no matter how you get the air into your engine it still contains less oxygen. It'll cost you a lot of money to make the car perform better than it did at sea level.

IMHO none of the things you listed will help much. sorry


er, I mean an air foil is the answer. It's good for at least 12 horsepower! :crazy

Gotta squeeze that air

Better intake will offer minimal improvement but you are starting at a disadvantage to sea level.

Thanks for the input guys. Also, I guess that after reading this thread, www.corvetteactioncenter.com/forums/showthread.php?t=62715 , in the C5 section, I might wanna stick with DELCO filter any how!
