That is definitely the way to go...i have tried both the weapon R and S&B that comes with the KKM. The Weapon R doesn't get heat soak as much because the filter is held in place by plastic. The KKM S&B on my car would attempt to implode on me. When idling with a quick goose of the throttle the S&B filter would sort of "crush in" or implode. This made me think that the s+b KKM filter does not have enough surface area. I am going to go with the larger MAF adapter and a large ass K&N or S&B filter...The Weapon R is junk! It also made a crazy ass air rattling noise when the secondaries kicked in.
