i have had excellent luck in terms of longevity with odonnell plugs , interesting you say that Eric?

i am not a fan of novarossi plugs if you cant tell





dnebout - the 21-7fms is spec'd out by chris nunez (employee of fusion motorsports/novarossi usa) and jim hottinger (owner/importer of fusion motorsports/novarossi usa) i know them both very well and they are very good people .

we learned a while ago what happens when people try to mess with him though (blktransam) , be honest about your engine when it comes to warranty issues and you will get great service , if you aren't , well............................ you won't


FMS is a cross between a p5 and 21-5k in port design 1-horizontal rear main intake , 2-large vertical rear main/transfer ports , 2-horizontal transfer ports , 2- vertical transfer ports and a tri-turbo exhaust = lots o' power

engine also comes with rear main ceramic , highly worked crank with putty filled intake ramp for a more direct throttle response .


the whole engine just works very well at making lots o' power
