Any benefit in upgrading to R8 coil packs?

[Gekbi]

The Audi service advisor mentioned that a popular tune on Audi's is upgrading to R8 coil packs. He says that the engine in my 2014 S7 is prone to overheat, which can lead to misfires or not as powerful sparks/ignitions. Although I didn't notice any issues (I was at the dealer picking up a part), and I don't live in an exceptionally hot region (Chicago), like the desert. Any truth to this?

The R8 is naturally aspirated and has less power/torque per liter of displacement than a turbocharged V8…meaning the coils have to overcome less charge air density across the spark plug gap. So maybe the question really should be “is if there is a benefit to upgrading R8 coils to S7/RS7 design.?”

Just because Audi charges more for R8 parts doesn’t mean they are better. There’s a thread on R8talk.com discussing “The R8 Tax.”

In opinion: the different engines have very different designs. Stick with the coil Audi picked for that design.

If your coil packs are bad, you can consider APR coils as they cost less than oem.

If your coil packs are bad, you can consider APR coils as they cost less than oem.

The price for APR is $45 each. The price for OEM at EuropaParts website is $64 each.

Marketing claim from the APR website: "The commonplace replacement of factory ignition coils with those taken from the higher output Audi R8 is popularly believed to provide greater energy output. However, testing proves that they are no more powerful than the factory coils that are found on other engines. APR Ignition Coils increase energy output by up to 6% over stock. They are a direct upgrade or replacement, and come with a unique red housing!"
