Owner reviews for ignition coil

All 4 coils (they´re now Bosch red color)

My Denso coils have been running fine for 3.5 years now. 6732312 (673-2312) was my part number for 2nd gen

10/10 the hitachi coils are genuine and have been solid on mine for 30,000mi.

Bought my Hitachi's from Rock Auto, don't remember the part number but I bought OEM replacements. 30k later and I'm still trucking.

Rock Auto is legit. I bought the Denso 673-2308 coils for my Fit 2 years ago and have had no problems with them.

my first bmw was a 2007 328i and kept having misfire issues. Tried 6 new coils from autozone, still had misfire issues, returned them and ordered Bosch. Misfire was gone.

I just put the latter on my 2000 S, they work well.

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

Never had good runs with ngk

Bremi ignition coils would crap-out
