From: "Peter Park"Subject: NACA Duct Designed for 1.6 -- Does it Work on '94 1.8 engine? Date: Sun, 4 Feb 1996 16:17:23 -0500
o The NACA Duct was originally marketed for the pre- '94 1.6 engine with mounting on the driver's side. o I presume the driver's side placement was due to components benefitting from the increased airflow being on that side? o Does the same hold true for driver's side placement on the 1.8 liter engine? o There is at least one message on the boards that implies that the NACA duct is non-functional for any MIATA engine and is cosmetic only? o Need the facts for decision to buy one or not for my 1.8 liter 94 M edition -- I have no other preformance enhancements/mods onboard.
