I'd say the AEM Dryflow (Koup-R) drop in if you can.
$60, but you never have to replace it again. It's cheaper to clean than a K&N because it doesn't need the oil kit. You save a bit of gas and it gives you a bit better response. It's the gift that keeps on giving. With the gas savings you can get other mods. It doesn't cost money it saves money!
