Ruthless Racing Intake Manifold Girdle : Secures the intake from coming apart as the two pieces are glued together. This kit covers the two pieces and holds like a large clamp, providing added strength to the Sea-Doo 1503 & 1630 Rotax engine intake manifold. The billet aluminum bracket clamps around the side of the manifold easily without drilling or grinding of the stock manifold, providing extra support to the joint that is known to split under higher boost pressures on modified craft. Anodized to prevent corrosion and includes stainless hardware.
