Title: VAG TSI/FSI Coils on M42
Post by: wazzu70 on February 08, 2015, 12:13:53 PM

I bought a VAG coil to see how it fits on the M42 valve cover. I have used a few different setups, but I was curious to know how these worked out since they have the igniters built in and are "smart" coils. For people going standalone this can have a huge benefit as not all systems have igniters buit into the ECU and would otherwise require a spark box to control dub coils like the M50 coils. The coils still sit too high to make the "BMW" plug cover work, but I think they fit better than the M50 coils and actually have igniters built in to them at a much lower cost.

Part number tested was 07K 905 715F, cost is around $25

Very nifty. I've been going back and forth on what the best plan of attack would be for ignitors for my Microquirt unit, and this may be the ticket. Are the coils secured in place in the pictures?
