i have a 99 accord 2.3 lx sedan which i removed the big resonator box from inside the bumper, and added a K&N drop in filter, since it was only a $25 mod ($25 for the filter only, purchased online).. draws cold air from inside the bumper now.

but prior to, i was considering a short ram intake system, that stops where the air filter enclosure sits,
supposed to take in more air, but in the summer i'd have to worry about heat soak.


which one will yield the best power gains / delivery, overall?

yes, i know its not a performance engine, my 98 prelude fills in the flanks there.

but i figured mods like these are so easy, why not?

 

SRI = hot air intake. It's going to be sucking in warm air from the engine bay. It will make more noise but that's about it. You're not going to see any noticeable power gains with any kind of intake on an otherwise stock, economy 2.3L. The setup you have now is the better option.
