The CSF 8401 No Limit is a billet intake manifold for a custom B58 cooling and induction build. It does not contain an integrated intercooler: an external air-to-air or air-to-water cooler and custom charge piping are required.
CPC 6061 billet construction, internal velocity stacks and a flange for a 77mm S55 throttle body support a conversion-focused layout. A port-injection rail, six block-off plugs and thermal spacer are supplied. A second rail can be added separately when the fueling strategy calls for twelve injector positions.

Product FAQs
Does the No Limit manifold include an intercooler?
No. It is designed around an external intercooler conversion. It is not a drop-in replacement with a built-in water-cooled core.
Is the second fuel rail included?
No. One rail and six block-off plugs are included. The 8404 second-rail kit and injectors are separate.
Can it use the original throttle body without conversion?
The flange is designed for the 77mm S55 throttle body. Plan the throttle body, harness and electronic compatibility as part of the conversion.
