PFYC has a sale on K&N's every once in awhile.
You'd have to check here: https://www.g6ownersclub.com/forum/fo...play.php?f=190
I hear that Crabs gives Forum members free shipping on the FPU when purchased with an O3 intake. Saves you about $18.
As for group buys I havent seen one for an intake...well...ever. lol
