Most everyone selling on the 'net to the US market sells for $325 to $350, but you can get them, shipping included, from for $250. It's a steal, I know, because I just had to buy one. >> The bad news is that you will most likely >> need one every 65K or so miles. > >I have never had to replace a DI cassette, and some weeks ago I saw >an old 9000 with the original DI cassette (the one with the connector >at the end of a short cable) still in place. From what I can tell, them older (pre 1990 ?) types were more dependable. The mid 90's & up and on seem to go with fair regularity. What shocked me was the rapidity with which it went... one day I had a serious engine hiccup while driving that went away after a mile or so. It did throw a misfire code to the ECU so I was watching it. It was fine for the next 25 miles on the next day. The day after that it went almost completely on a short 1 mile jaunt. I expect that maybe two cyl's were firing. Luckily I was only a mile from home. So, all in all, it was less than 30 miles from "initial warning" to "barely made it to the driveway". Thinking back through, it was idling a little rougher than normal but I didn't really notice that until I replaced the DI and saw the improvement. I assume it was misfiring a bit - but the bad thing is that it was not throwing computer codes until it got close to dead. >If I had the choice between an engine with a traditional ignition >system with electronic ignition module, distributor, distributor cap, >ignition coil, and spark plug wires or an engine with a DI cassette I >would, without hesitation, choose the engine with DI cassette. Me too, although I wish they made the individual coils replaceable like my Nissan's have. It only costs $75/cyl to do them and you can plug and play to see which are bad. Bob
