Ignition coil Bosch or APR

I gave the Jetta back to my son last week after replacing the coil. No issues yet - but mine was happening less frequently.

Been over a week with the new coil installed. No failures.

Yes, it's installed, and I have not had any failures since Monday. It was failing maybe every other day, maybe two times in a day.

So far, it's been four days without an engine start failure since replacing the ignition coil.

I just replaced coils with bosch, VW Ignition Coil Service Kit - Bremi 06E905115EBR2 , so far, works fine with no problem.

In my experience the Bosch ones last 100k miles. I've sold and installed thousands and I'm not sure I've ever warrantied one.

I decided to order the OEM Bosch coil off of FCP Euro. Same issue about a 1/4inch too long. Being kind of annoyed and noticing that they're pretty much identical decided to pull the rubber boot off the old and swap it with the new one.

The car now runs a lot better, however, I think the slight difference in ignition coils is making the car run slightly choppy at high rpms

The Delphi coils are junk. Bosch updated the coils they offered and we've used the updated coil multiple times and never had to warranty a single one out in the 4 years we've been installing them.

Everytime we've used a Delphi in the past the white silicone on the boot degrades and falls apart in 6-12 months and customer cars came back with misfires again.

The old Bosch coils wear out because people don't do spark plugs and replacements on time. The old plugs end up with crazy gaps and it kills the coils. Usually at 100k-120k miles but honestly that's the normal lifespan of a pencil style coil regardless.

If you're plugs are old and you're beginning to experience misfires then save yourself the time do all 6 plugs and coils. Your N52 will thank you.

APR coils lasted almost a year (5/6000 miles) when I pushed it and let go of the pedal. CEL would flash and random cylinders misfire.

As stated APR coils are know to not be as good as OE/OEM. I have seen a lot of people with APR coils chasing misfires and the replace with OEM and it’s fixed. Even with new APR this has happened.
