Re: Northstar injectors

pocket,

I would take them down to a cadi dealership. Maybe the parts dept can look them up by the pn number or some kind of stamp ID number.

Re: Northstar injectors

Found it

23.5#

They are the same physical size as TPI injectors and use the same electrical clips

So these will interchange with stock TPI injectors? (Damn newb questions... )

Correct me if I'm wrong. I haven't read up on TPI for years and just getting back to it.

305TPI are 19#
350 dunno...

350 is 21lbs. They'll work, but might be a little rich in open loop.
