3.5in Collector Ring Kit

The 3.5in Collector Ring Kit from HOOKER is an essential component for serious anglers and boaters who demand reliable exhaust system performance on the water. This marine-grade collector ring kit serves as a critical junction point in your engine's exhaust manifold assembly, designed to withstand the corrosive salt water environment and constant vibration inherent to boat operation. Whether you're running a center console, cabin cruiser, or high-performance offshore vessel, a properly functioning collector ring ensures optimal exhaust scavenging and engine efficiency.

At 3.5 inches in diameter, this HOOKER collector ring kit features precision-engineered construction that consolidates individual cylinder exhaust ports into a unified manifold passage, reducing backpressure and improving combustion efficiency. The kit's robust design minimizes turbulence and heat loss, allowing your marine engine to breathe freely under load—critical during extended cruising or high-RPM performance runs. Engineered to handle the thermal cycling and saltwater exposure that standard aftermarket components cannot, HOOKER's collector ring maintains structural integrity through years of demanding marine service without warping or corrosion compromise.

This collector ring kit fits most standard marine gasoline engines commonly found in mid-range recreational and performance boats. Installation requires careful alignment during manifold assembly to ensure proper seal and exhaust flow integrity; most experienced mechanics can complete installation during routine engine service or rebuild. The compact 7.85 x 9.85 inch footprint allows straightforward mounting within standard engine compartments, making this kit an ideal upgrade or replacement for boaters looking to restore lost performance or prevent mid-season breakdowns on the water.
