Hello to all. I’m strongly interested in upgrading my factory ignition coil packs which have been on the vehicle for a long time. I have a ‘91 TT which has what I considered a mild build. It has 740cc injs,, upgraded TBs and Ash Massives and Garrett 2860RS turbos. I was curious to see how many of you have considered or tried the R35 coil packs conversion kit from Polar Engineering. Or is staying with brand new OEM ones sufficient? Let me hear some of your inputs. Thanks!
