Sorry, what is the advantage of these for a 12 month 13,000km stock (and always will be stock) GTi? My previous Audi A4 Quattro killed on at 20000 but the next didn't die until 130,000

is the VW GTi coil packs more fragile?

The main advatage is the R8 coils are a stronger coil. If you don't run a tune then you'll probably be OK.

For anyone running a tune the stock coil packs are a weak point and are prone to failure.

So benefits are:

1) engine bay bling
2) keeping on the road

I've had a coil go and caused the car to go into limp mode. It wasn't fun. Fortunately I wasn't too far from the dealer, however car was off the road for 3 days.

This info is testing done by HStuning and originally posted on the Mk6 Golf site:

For those of you looking for more technical data on these coil packs, here is what we've found so far with our bench ( oscilloscope ) testing:

1) These coils can be used on your FSI/TSI engine at ANY level of modification. They function just as well on a dead stock car as a highly modified one.

2) They are NOT the same coils with red housings. The secondary circuit on the R8 coils has a higher resistance (more windings) than the stock coils. In fact the secondary circuits were slightly closer to the Okadas we tested than the secondary of the stock coils.

3) We tested these between 12 and 16 volts (remember if your alternator is charging properly the input will be right around 14). We tested them between 200 and 16,000rpm. The stock coils started to misfire at a much lower rpm than the R8's with a stock spark plug gapped @ .032".

4) The spark was visibly brighter and more intense on the R8's when compared to the stock coils @ every rpm we compared in the stock rev range. We didn't compare anything under 1,000rpm.

5) We were able to open the gap on the plugs much further with the R8's than the stock plug with out misfiring at the same rpm/voltage.

6) Here is what we were finding as an AVERAGE on the secondary circuit for each of the coils.

Stock: 3.3 M ohms
5 cylinder coils: 4.75 M ohms
R8's: 5.31 M ohms
Okadas: 6.2 M ohms

So there definitely is a difference. There are quite a few people that have stock coil packs fail - particularly when you start having your engine tuned.

It is a real PITA to have a coil pack go and be left driving on 3 cylinders (from personal experience). You might get lucky and have no problems, though for the cost of the coil packs it's cheap insurance against getting stranded.
