currently my silvertop 20v is running no trumpets in a custom air box, it goes hard but my only comparison is what was there b4 (4ac). what i would like to know is what size, length etc is best. the standard ones were really long and weird shaped. i can't do long ones as the airbox won't allow for it. i am not looking for bullshit power increases just optimising what i've got. thanks kiddies!!
fit as long as you can in the airbox without restricting the opening
