Among the most anticipated additions to the product line is the icengineworks’ NP Series. Engineered to assist in the design and fabrication of advanced turbo manifolds using standard Nominal Pipe elbows, these blocks simply snap together to create custom and compact manifolds designed for your specific engine bay. Included adaptors allow you to attach modeling blocks to the exhaust flange on your motor. Also available are cutting kits, which allow you to make quick and accurate cuts perpendicular to the tangent. Save time, material and money with these handy kits!
