Their are some mufflers out there that will fit already like the Aero Turbine AS2525, The Fastman makes a t/b for the 3.7, ASP makes an underdrive pulley , spark plugs can be added like NGK2262's, AEM is looking for a test vech. in so/cal for an intake. And could anyone tell me if the Nitro 3.7L has a clutch Fan as I have a spare Extreme 180 Flexalite waiting to put on mine when it gets here. As for the intake I have a 360 kool shot that I used on 2 diff. 4.7L dodges I've heard that it would also fit a 3.7L.I think this would be a pretty good start for those who don't want to wait for the 4.0L . These are of course all 3.7L mods. Just some ideas.
