the s5 has 2 vacuum nipples pointing horizontally at each other between the secondary injector holes.

The egr passages are in different places. You have to see the engine mounting face to determine this. The S4 has it's passages in the center under the primary ports and the S5's have them on the outsides under the secondary ports.

Keep in mind that while some people here claim one flows better than the other, this isn't the case. From a flow standpoint, they are identical.

I believe they both fit the block but the runners are different where they meet the uim.

The runners pysically line up just fine. The rear most bolt hole is moved over though. The others work. You can modify that bolt hole to work.
