Best bolt ons for a small block

What would you recommend for a air filter? K&N?. Back in the day I used either a Fram or a Wix. Like to get the most from every performance dollar spent.
No. K&N sucks and not in a good way. There've been many people show that the K&N filters, while they allow more air to flow also allow more dirt. Some say if you keep the filter oiled they're good, blah blah blah, but who the hell keeps up with that kinda thing? So I always recommend an over the counter paper filter like WIX or another decent brand.
