02 accord 4 cyl performance mods?
 

is there anything i can do that really works? am not a big believer in 'cold
air intakes' and am skeptical about the low cost ecu mods. it runs ok, but
need some extra smash for passing. have looked at the 4-2-1 headers, wonder
if anybody has tried it and found that it really makes a difference. dont
want to spend the big bucks on a turbo- or super-charger. thanks
