E63 Billet intake manifolds (W213) w463 Have a shorter insulator and

Have a shorter insulator and retains less heat at the tip end are only required when higher boost levels cause increased cylinder head temperatures

Reduced restriction for increased flow rate and less strain on coolant pumps

E63 Billet intake manifolds (W213) w463 Have a shorter insulator andM177 LS2 BILLET INTAKE MANIFOLDS The factory manifolds are constructed from plastic, in 2 halves and then plastic welded (melted) together) This construction method is economical for large scale production, and (mostly) ok for standard engine power. However, the limits of the factory manifolds are well documented Furthermore, the plastic is not able to be drilled or tapped, so optional ports for nitrous, meth, or boost sense cannot be added. Finally,
