, our hemi's like to breathe and aint no one gonna tell me this isn't going to work, I've run mine for many years watchin my track times really start to drop after I installed mine...
I don't disagree with that logic at all. The more air you can get in/out the better. Hence the reason for forced induction. The difference is that the "real fast guys" have a lot more mods than the average guy just looking to put a CAI on; maybe an exhaust as well. Comparing apples to oranges doesn't help anything.
Even with a heat shield I wouldn't consider that a CAI as it's still an open design. The stock system is not like that, it's completely closed in the engine bay. Same with an S&B or Volant intake. IMO the K&N and intakes like it are a short ram intake. Yes they may flow better but aren't always getting as cold of air as the stock intake. If you're building a race truck then that's not an issue. But for a daily driver that's not moving as fast and sitting in traffic quite often a closed design is better.
As far as the horsepower goes, putting aside the fact that it was done by K&N themselves, the pull starts at 2500 rpm. Again, the average guy using his truck as a daily driver isn't getting into that power range very often. At 1500-2000 rpm where the majority of guys are running their trucks 95% of the time there isn't going to be any gain.
While I don't disagree that air flow and getting as much of it as possible is a good thing, I don't want there to be any misconceptions that guys are gaining 17hp (or whatever the dyno sheet says) from idle all the way through the power range. It's not like that...
