The cost for an Apikol kit is $345, and the 034 kit is $355.  If you brewed
your own, I'd say that you'd be staring at $200-250.  These are in United
States greenbacks, naturlich.

I have the 034 kit.  Instructions are missing one step, but it's obvious
what's going on when you start unplugging the car's electrical connectors at
the firewall.  Other than that, it's a well-designed and put-together kit.
It took me all of 10 minutes to put it on.

The other hour I spent was changing the damn spark plugs.  (Thanks to Dave
F. on that as well - the tool list was very helpful.)
