wait. i just read the 1st link you posted and it said they lost power and had dyno (dyno 3 m5 forums) runs to show it... but the air duct idea isnt bad. and i read that some of the honda ppl retuned their cars to get some power. but we'll see when u get urs. wheres the a/f shot in those? and for the ppl running without filters.. dont we need filters?
