By putting in an electric fan, a new ignition system (Accel 300 ) and a K&N air filter will I see an increase in power? I know it will not be the 4.0L but if it would be noticable I will do it. All the parts I can get from Quadratec for about $500 and I can do it myself so that would also be the final cost. Is it worth it or should I not waste my time and money. I almost never go above 3000 RPM if that answers any questions so I am looking at the low range for power. Thanks for any input.
