I can't see the point of the balancer on a 4 cylinder. To me the balancers are a novelty item. Balancers come as standard on "V" engines from the factory so they must be of use in that application otherwise the factory wouldn't fit them. But I can't think of a single examaple of a 4 cylinder engine that came from the factory with a balancer. 4 cylinders are big business over here because thats what we've always had and again I don't of any form of after market harmonic balancer for any make or model of 4 cylinder engine. Are the balancers just not a carry over from the world of V8's? The attitude that its works on 8's, so it must work on the 4's?
