I am interested in getting some manifold insulators, however can't seem to find SIDI ones on your website? However I saw the VZ-VE Alloytec insulators, and just wondering if they would work for SIDI engine as well?

Yes.We do have them on our website, as shown in the link below:

.In saying this though, would need to know the engine type, which would be stamped on your compliance plate, which is located on the passenger side strut tower.Fortunately we do sell both 3.0L and 3.6L V6 manifold insulators for SIDI engines
