I have a 22 G70 3.3 and was thinking about getting the JB4. I have no intention of modifying anything other than a K&N filter. Will I get a performance increase close to 400 - 450hp? Also, I'm concerned about how it effects the warranty (which I still have). Does anyone have bad experiences with that?
