wizrdovoz twinspark manifold fitted!

please see this thread here:

https://www.alfaowner.com/Forum/just-...wizrdovoz.html

description shamelessly double-posted below!


right, i have the car back, and tis excellent! needs a throttle reset, but overall its smoother, more free revving, and quieter than with the supersprint manifold fitted.

its still got a "rasp" but this will quieten down once the manifold is carboned up inside.

the whole exhaust tone has changed, i will try and get a sound clip, its not as deep a sound, its a little higher note, but theres more of a burble, which makes the car sound more.....Italian.

cant think of a way to put it better!

ony *slight* downside is it sits touching the water pipe going down to behind the oil filter, heat exchanger area, but this pipe will be heated and moved slightly next week.

overall, im damn happy.

price, quality, performance all superb, will describe it again when the car gets mapped next week.
