Ignition coil Bosch or DELPHI

I did Oem plugs and Bosch coils. No problems so far.

I use the Bosch, and Ive been happy with them so far.

Bosch.

Never had issues with the Red Bosch ones I got from Shopdap.com But plugs, I preferred the NGK Ruthenium HX over the Laser Platinum, and Iridium-IX

I have used the 027 coil in a beetle with with points and the coil was getting hot. It was solved by using the 039 coil (Bosch grey).

Had thrown some 2 years ago and still running clean as ever

Delphi will be all you need. Delphi are fine even on ST setups running 700+whp. There’s really no need for others.

Stepdad recommended replacing ignition coils, so I purchased a 4 pack of Delphi GN 10369 from amazon. Sure enough, we just replaced the coils, and boom, it ran good as new (to me).

Many aftermarket coils are completely out of spec and do not work well, some can even destroy the ECU. OE, Bosch, Temic are all good, I believe Beru is an OE manufacturer as well.

Just replaced my coils. AVOID Bosch. Literal trash that does not even work.
