I installed it as directed but it didn't work - wouldn't produce a spark. I had to re-install the old one which is working fine. The reason I wanted to replace the old one is because I had one instance of not getting spark and I suspected the CDI/ignition coil was the problem. Since this is an electrical product, I can't return the new one even though it didn't work out of the box. I've used other SPI products before and have had good luck with them.
I bought this for my 2007 Skidoo MXZ. It solved my issue. That was about 6 or 8 years ago. I just bought 2 more for a 2008 MXZ and 2008 380F. Its's a good fix. The sleds are running top shape again.
