Exedy 2006-2006 Saab 9-2X Aero H4 Lightweight Flywheel
The Exedy FF502A is a lightweight flywheel for the 2006 Saab 9-2X Aero, the final-year Aero that moved to Subaru's 2.5L EJ255 turbo engine and five-speed manual. The 9-2X was built by Subaru on the Impreza platform, so this is the same drivetrain found in the 2006 WRX. Owners find this part when the original flywheel is heat-checked or worn during a clutch job, or when they want the turbo flat-four to rev and rev-match more quickly.
The flywheel bolts to the back of the crankshaft and does three things: it gives the clutch disc a flat, hard friction face, it carries the ring gear the starter engages, and its mass smooths out idle and low-speed take-up. Exedy's Sport flywheel line trims that rotating mass so the engine spins up faster between shifts and falls quicker when you rev-match a downshift. The trade is the usual one for any lighter flywheel: a little more care is needed pulling away from a stop and some extra gear noise at idle is normal. For a turbo car that sees spirited driving, most owners find that a fair trade, and the Exedy FF01 for the 2005 Aero is the matching part for the earlier 2.0L car.
Most flywheel trouble first shows up as a clutch complaint. Before pulling the five-speed, rule out a worn disc and the hydraulics with the road test in our slipping diagnosis guide. Once the gearbox is out, inspect the friction face under good light, measure runout with a dial indicator and check every ring gear tooth. Light glazing can be machined off by a shop; cracks or deep hot spots mean the flywheel should be replaced. If the car is mostly a commuter, think honestly about whether you want a lighter wheel before you order.
This listing is for the 2006 Saab 9-2X Aero with the 2.5L turbo engine and five-speed manual. Exedy's own catalog lists FF502A for the Subaru models that share that drivetrain: the 2006 to 2014 Impreza WRX, the 2005 to 2008 and 2010 to 2012 Legacy GT, and the 2005 to 2008 Outback XT. It is not the part for the 2005 Aero, which uses the 2.0L engine and the FF01 flywheel, and it does not fit the 9-2X 2.5i, automatic cars or the six-speed STI. If your car has a swapped engine or gearbox, send us the year and VIN and we will confirm before it ships. More parts for these cars are in our hard parts collection.
The FF502A is new, in stock, ships the same business day from the USA and is backed by a 1-year warranty.

No. The 2005 Aero used the 2.0L turbo engine and takes the Exedy FF01. The FF502A is for the 2006 Aero with the 2.5L EJ255 turbo and five-speed manual.
Mechanically yes. The 9-2X was built by Subaru on the Impreza platform and the 2006 Aero uses the same 2.5L turbo engine as the 2006 WRX. Exedy lists FF502A for 2006-2014 WRX, Legacy GT and Outback XT.
It revs faster, so pulling away needs a little more throttle and some extra gear noise at idle is normal. Most street drivers adapt within a few days.
Replace the clutch disc, pressure plate, release bearing and pilot bearing at the same time, and inspect the clutch fork and pivot for wear.
No relearn is needed for the flywheel. Bleed the clutch hydraulics and top up the manual gearbox oil if any was lost.
