I was having some misfires on two cylinders. I currently run the APR stage 1 tune on my Mk7 golf gti and the APR carbon fiber intake. I’ve had the tune for about 80,000 miles so it was time to replace the ignition coils. Decided to get the APR coils. The color options are nice. The blue looks really good in person. Noticeably heavier than the stock ignition coils. Happy with my purchase. I definitely plan on getting more APR upgrades in the future.
