I replaced the spark plugs over the weekend, and I’m doing the ignition coils tomorrow replacing them with brand new Delphi’s.
I changed my ignition coils to delphi aftermarket ones and the idle is nice and smooth now. But the old ones had like 200k km on them.
That's the Delphi coil. It's the updated part from the original all black Bosch. It's the only one I put in my customer's cars.
Delphi is considered the go-to for N52 coils.
My delphi has been running good for about 20k miles with ngk wires and plugs.
Stick with OEM from VW. They are the best choice
Replaced with Delphi coils and it hardly bucks, still does but not as bad as oem once in a blue moon for a half a sec.
Bosch Delphi eldor they’re all the same you can’t really say one is better than the other. Some go bad early that’s just what it is. I personally went with Delphi (they’re quite a bit cheaper on eBay). But the lifetime return/replacement from fcp is pretty enticing.
My first car was a Volkswagen Passat. I was on a budget and got a good deal on a really nice car. It was a dream to ride, except when everything kept going wrong. I went through multiple ignition coils, the car caught fire (bad coil, again) and had thousands in damage. Beyond that, getting tires balanced wasn\u2019t a simple job. Everywhere needed to special order shims from Germany because that\u2019s the only way a Volkswagen tire could be balanced.
I don’t like the Delphi ones cause they come apart, if you do spark plugs again say 20k miles passes you could deal with the silicone tube on the end getting stuck down when pulling them, then you gotta be careful and get the spring and that out without the spring flying off somewhere.
