I just converted my AEB style coil packs to the push down type, so I'm probably not going to be in the market for the FSI ones for a little bit yet. However I'd like to know if there's enough of a gain to make it worth my while to do the switch when the time comes to replace my pushdowns.
I don't have any instrumented test evidence, but the fact is that the 06H CPs, with the plugs gapped at 0.044", (factory gap on the NGK BKR6EIX-11), the engine idles A LOT better/smoother that with the 1.8T PN coilpacks. Being a Tip trans, before, the idle quality with D/S Tip mode engaged while stopped, was always comparatively rough, with the 06H CP, the warmed up idle is smoother to the point that it is almost not noticeable if in gear or not. Further, the throttle response is improved, and the midrange torque is higher, (according to me NIST traceable calibrated butt dyno). One aspect is clear evidence that the ignition quality is improved with a more complete burn of the air/fuel mixture, is that the CEL I had with the 034 HFC, cleared on it's own after installing the the 06H CPs, and has not returned. So, with the several objective improvements, this is consistent with the higher energy spark from the 06H CPs and the wider spark plug gap used, providing better ignition performance. Finally, besides the improved engine running quality with the stock ECU, running on APR stage 1, the engine pulls much more cleanly and does not exhibit the unsteady ignition quality at full load that occurred with the 1.8T coil pack PNs used before.
