This is very true. I have a friend with a Subaru who says that i/e mods will give gains more than 10 HP, and this is consistently true with Subarus. Same with a lot of American cars...the gains from simple mods like that are significantly larger than Hondas and that's because Honda has pretty much designed their engines to be about as optimum as possible.
