Notes:

Manual transmission models only. Not compatible with OEM B18C b18c4, ’88-’91 D-Series, or downflow intake manifolds. It does not fit F22C (F20C is ok). Designed for use on most aftermarket intake manifolds due to larger bore. Any manifold with a throttle body opening of less than 70mm will likely require modifications to keep the IAC passage separate.
