Hi gurus! I'm looking at getting a K&N drop in air filter for my '97 Civic VTI A/T. My question is, what should I expect to gain from this (if there is any)? Would it give more power, better acceleration, better fuel consumption, etc?

Just it case the drop in filter is not worth it, how about those other air intake mods (CAI/SRI)? TIA for the inputs mga sir!
