Ferrari Mailing List: Re: 308 Mods

[Grahame Reinthal (grahame]

Hi Hans,

Used original 328 plenum. Fitted 2 half fuel rails on the rear bank so as
not to block the plenum entry.  Put an extension between the plenum and
throttle body to clear the throttle mechanism away from the rails. Then
connected a flexible pipe from the throttle body to a K&N air filter mounted
near the right hand air intake scoop. Seems to work and looks quite neat and
tidy.

I posted some photos and blurb a while ago on Fchat but don't have them to
hand here.

Cheers,
 
Grahame

What did you use for an intake manifold?
