Ignition coil Bosch or DELPHI

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.

Always go Bosch. 55 years of wrenching and have never had a Bosch part that wasn’t top quality.

Don’t get Bosch coils or plugs. Get Delphi coils, they’re the updated design. As for plugs go with NGK

I like the R8 coils because they're cheap. At $20 per Bosch coil, you can throw an extra in the trunk without breaking bank. I did mine when my factory bolt downs went bad.

I’ve used both. Didn’t notice any difference. Have Delphi’s right now. Both work great for light and mid tuned setups.

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.

The R8 coils are cheaper then the standard Bosch coils so cheaper if nothing else.

Delphi quality has drastically dropped over the past 2 years. We’ve gotten multiple DOA units, and ones that fail within 6 months.
