Ignition coil NGK or OEM Audi

I have ngk coils in mine and they've been fine for 50k+ miles.

When I bought my 2008 VW Rabbit 2.5, it had 142K miles on it and I wanted to be sure I did a complete tune-up, not knowing its history. I bought the whole OEM unit which came with cover, gasket, bolts and PCV valve at a low price from Amazon. When I pulled the coils to replace the plugs, I saw that they were covered in oil from the leaking center section of the gasket, so I bought NGK coils to go with the NGK iridium plugs. When I pulled the plugs, I saw the tops were also covered in oil but the working end of the plugs were fine (Bosch plugs and the original coils). Replacing everything was easy and I torqued everything correctly. No more leaks and the car performs wonderfully on 87 octane.

There is one benefit to running R8 coils on a stock TSI. They seem to be a hell of a lot more reliable.

So, I went to my VW/Audi dealers here in Tampa and purchased the stock RS7 spark plugs and RS3 ignition coils. The exhaust smelled slightly worse at startup after the change, but still went away shortly after startup. The idle was smoother but I attribute that to old stock coils and spark plugs.

The only thing I have are the R8 coils, other than that stock everything. The car drives mint

The Audi bolt-down ones are good. I replaced the push-down coils that had a failure about every year or two with the bolt-downs just a week or so befor VW announced the recall. Zero, zero, zero problems ever since.

So far I've replaced all ignition coils (1 died while I was test driving the car, the other 2 years after in the winter, of course). I decided to replace them all with non-faulty Audi parts instead of doing it every year.

Coils I've tested as follows:MSD, Blaster ss/Accel electronic super coil/Accel canister OE replacement/Audi 5KTurbo OE \"E\" core epoxy coil/Ford OE EEC-IV(TFI) E core coil. Results..OEM VW canister oil coil=unable to increase plug gap/difficult starting *sometimes, rough idle MSD Blaster coil=seemingly quicker starts, smoother idle, able to increase plug gap, coil runs hot Accel electronic(square super coil)=pure junk, worked as well as the MSD for starting, however upper revs missed with gap opened, and coil failed within 1 year Accel canister coil(OE replacement)=no noticeable difference from VW OEM coil Ford TFI/EEC-IV \"E\" core coil=plug gap opened larger than MSD, no missing, coil runs at normal temp, quick starts, smooth idle(best of tests of all coils)however;these are known to fry occasionally, must keep a spare. Audi 5KTurbo OE \"E\"core coil=plug gap limited to 0.034\" from 0.028\", easily handles up to redline without missing, runs cooler than other coils, good starting all weather and smooth idle. I currently use the Audi OEM 5K Turbo \"E\" core epoxy/plastic coil and combined with MSD 9mm(50ohms/per foot) custom made wires and the re-wiring of the coil(+)terminal with a Bosch 40Amp relay with 8gauge(Monster Cable) power wire with gold plated terminals........the reason for re-wiring was I noticed around a 1volt drop between the battery and the coil(+)terminal, after adding relay/power wire(10gauge would be fine as well)the voltage is exactly battery voltage...after re-wiring the coil I was unable to ever get any missing in the higher RPM's. And a slight increase in power*seemed* to be felt, but no dyno proof....gas mileage did increase about 4 miles/gallon!!(original mileage was probably poor from crummy OEM wiring)

I would stay away from NGK coils, I replaced 4 in my Honda and in 2 months one was out and another starting to go out.

After only using the NGK coils for 2 days and when I went to switch them they were fried !!! Complete gone
