It's 2 hours labour and you have to remember that when you refer to it as 'just connecting a couple of wires', it's actually a bit more than that.

We have to site and mount the valve, and pipe it up, which on some cars is a real arse and also mount the unit.

When you're doing it yourself it's OK to just chuck it in, but as a proper reputable garage, we can't do that.

Apexi AVC-R's have about 6-8 wires to connect, into the main ECU loom. They all vary. We fit lots and get no complaints from the Jap boys about what we charge.
