Questions & Answers
Is this a genuine original part?
This is a premium quality RecMar aftermarket replacement set, manufactured to meet or exceed original equipment (OE) standards for fitment and thermal performance.
How do I know if I have a "Dry Joint" system?

Does this kit include everything for both sides of the engine?
Yes, the RMV8DJSET2 is a complete kit containing two manifolds, two risers, and all associated gaskets and bolts to service one complete V8 engine.
