I have a Leyland? Inlet manifold and I am going to replace the 1-1/2" SU with a 1-3/4" SU.
Should I invest in a Minispares (or similar) manifold and will the Ramflo air filter fit OK as these inlet manifolds are longer.

A Minispares single HS4/HS6 manifold fits, however you will probably not be able to run the donut air filter. Fit a Ramflo, K&N or similar sports filter. Here's my 1412 stroker with a 20mm thick spacer on it:

Is there a significant benefit of the Minispares manifold over the Leyland even if the leyland one is ported as DVD A Series book. |

A lot less work to fit, and they are pretty cheap to buy, even here. I'd say they will outflow a ported stock HS4 one. |

That's NOT a stock HS4 cast iron manifold. That looks like the MG metro manifold, it's alloy and flows pretty well according to Viz. I doubt you'd get much (if anything) going to a minispares manifold over that. cheers, Jacob |

Looks the same as the one I bought second hand from the UK. And you can see the grooves in the photo that indicate that a 44 (1 3/4) has been previously bolted up. Mine looked as nice inside as the much shinier (and expensive) Mspares version... Cheers, Ian |

Looks like the MG Metro manifold. Build for the HIF6 and flows very well. No need to change. M |
