I have seen lots of Efini parts for sale, but who are they? All 99 spec bodywork comes from them.

Efini isn't a parts provider or anything like that.. that's what they call an RX-7 in japan.

Eini was another line up of higher end cars in japan. Like Acura is to honda .

this went from like(not sure the starting date) 1990 to 1998 for the RX-7.

It consisted of several cars like the MX-6 also.

In 99 they went to the flying bird emblem, and lost the Efini name and stuck with Mazda.
