This set is made specifically for Hasegawa’s F/A-18 E/F kits and as Hasegawa’s EF/A-18 G Growler is the F/A-18F kit with extra sprues for the Growler add-ons, it can also be used on the Growler too.
The set consists of 6 resin parts, three for each exhaust. The parts are the actual nozzle, the exhaust can and the rear face of the engine. The parts are extremely well cast, as expected from Aires and in comparing the parts to photographs of the real nozzles, Aires is spot on, capturing the details perfectly.
