4 degree ignition advancer

[PieEater]

I have one fitted to my full montied Gen1 the altered timing gives better low down response at the expense of a few BHP off the top. It's made cold starts a doddle and low rev cruising even easier,  you'd most likely notice the benefits of fitting one rather than the slight loss of top end. I don't really see what Ivanising has to do with it as the effect will be the same regardless but others will no doubt have an opinion.
