Thread: Injectors for a 4.6 build.

So if your LR injectors are working is their any advantage to changing over?

Mine were working when I changed.
IMHO you get better idle stability in a 3.9 anyway. Idle used to deteriorate after a while with the old Lucas injectors. It was cheaper to get a set of reco injectors from the states than to have the Lucas ones cleaned. The problem with cleaning is that if one or more die in the cleaning process you are up for a new Lucas at big cost . Ask me how I know as 2 died on me.
Its hard to say whether you have better performance or economy as in my case I had many other modifications . However I felt that the engine ran more crisply and I had better economy. At the end I was getting about 17lper 100 around town and about 15 on the open road towing a 1000Kg trailer at speed limit.

The 14CUX fires all the injectors in one bank all together and some obviously fire against a closed valve so this may mitigate against the better vaporisation of the four hole injectors. I felt it was worth it.
