Whats your open cone filter setup.The only $30 and under mods may be the Cai .Does the cone reach the opening behind the headlight.I dont know if you can run a Fwi or not but you might want a heat shield , the cooler the cone and pipe the better.Put in a 180 thermostat.Not much elseTry bonneville club .com
