Ignition coil Bosch or Denso
For a simple, plug and play upgrade for the ignition coils, the Bosch coils from an Alfa Romeo 4C are better than the stock Beru coils or the Mopar coils found in the Dodge Dart.
Your repair is reasonable in Canada or the USA. For those that don't know what a base Jetta coil pack and wires looks like, here's a link to FCP : VW Ignition Coil Service Kit - Bosch KIT-032905106FKT3 | FCP Euro https://share.google/2UaBCZUOxCYsInqvp
You would probably get these on TEMU for 80 euro. Stick to BOSCH or NGK.
If you go to Autozone and open the box of their 2004-2005 coil pack, IF it has a "Denso" or "Made in Japan" sticker on the bottom, it's 100% OEM.
Do not buy shitty eBay “performance” coils for a 1.4 touran. Just go to a motor factors and buy a reputable brand like Bosch.
Running much better now. Will eventually replace the other three ignition coils, but those Denzos are $90 a pop.
I did manage to find the oem plugs (12290-rb1-004) for $32 each from hondapartsnow.com and Denso coils from AutoZone (673-2312) for $65 each shipped.
Bosch WERE awful when first introduced, but lifted their game.
The coils are Bosch and I assume the OEM from factory. I know they car is 18 years old, and I don't mind replacing them, but I'm curious if age, and not just mileage, plays a factor in coils and spark plugs. Manual says change spark plugs at 100k and it seems unusual to me for coils to fail with so few miles on them. I've had several other cars with over 150k miles that never had a failed coil, and one car even had over 250k miles (and about 25 years old). Could there be something causing these coils to fail prematurely? Should I look for a different brand than Bosch?
I chose the cheaper Bosch ignition coil. When I got home, I realized the spring inside was significantly shorter than my old coil's spring. I made no risk of putting this in and brought it back. I learned that Bosch parts used to be made only in Germany and were excellent, but now many are made in the US or China and are poor quality. The one I got was definitely not the German quality.
