im just starting to fit a plenum spacer to my sapph.the fuel rail has had to be removed to remove the cover.will the fuel rail fit ok when the spacer is back on seeing as it bolts to the plenum cover and when the spacer is fitted it will sit 12mm further away from the injectors.

 

It's only the 15mm spacers I belive which are a direct fit, albeit with the rail bolted to the other side of the lugs. The 10mm and 12mm ones need the 2 lugs filed/cut down so the injectors fit at the correct angle... easy job!!!
