There all about the same realy the stock setups very good realy the same design is used on the whole range upto the 105 hp model. IK or custom intake is needed if your going to push over 120hp or your despirate. The 57 kit is probably just a rempacment panel filter? If so its better but no gains worthwhile.Tigger said:There'll be less power loss with the panel than the IK then.
Would it loose much power with the 57i induction kit ?
