The inlet manifold has to come off for one of the cylinder banks (3 plugs). Some people have found you can replace 2 out of the three without doing this, but this is not really the right thing to do !!
You may need a new gasket, but others may advise here. Jaguar interval to replace is 70k miles, but advice is to do earlier, (circa 35-40k) to prevent them seizing up in the head from corrosion.
