Ignition coil Bosch or HITACHI

My 2018 Civic is Hitachi.

I bought the Bosch 4 yr and 10k miles ago and haven't had issues.

I've switched from standard to the Bosch ones last summer and it significantly improved the acceleration on my 124 Abarth. Prior to the switch I'd see lots of misfires and "bumps" in the power delivery curve. The Bosch set was not a hard sale with being under 280€/260$ here in CZ. Highly recommended for anyone with power mods.

I replaced my coil around the same time, and no start failures for me either.

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.

I have changed the ignition coils, spark plugs, MAP sensor, fuel filter, and ran fuel cleaner in the tank twice. The only time it seemed better was for a couple of months after I changed ignition coils (Bosch).

I have them with APR Stage 1. R8 coil packs are not really an upgrade that people make them out to be... red = more performance.... Sure they came out of a R8 and V8 Touareg "BAR" engine code... but the coils make enough current to get a spark. The spark plug does the rest, and the features of the spark plug help with getting the air-fuel mixture ignited and burned. Because of the popularity of the red coils, you can often get them cheaper. I think last time I paid about $100 for the Bosch red coils from ShopDap.com

9-3’s eat coils; it’s a forever problem on my 9-3 that it seems like every 30k miles I’m spending $200 on new coil packs. It’s essentially routine maintenance. I ordered Bosch OEM coil packs off RockAuto and just now realized they have a warranty. I submitted a warranty claim and they sent me out brand new units. Wish I would have known this because it would have saved me lots of money.
