First-generation FA20 FRS/BRZ/86 direct injectors. This is not a casual O-ring swap: depressurization, cleanliness, injector identification, seal installation/sizing and leak checking matter. Do not attribute every high-RPM misfire to injector seals without diagnosis.
OEM numbers
Genuine four-injector combustion-side seal kit contains SU003-00322 x4, SU003-05632 x4 and SU003-00321 x4. The checked installer/sizing tool path is a genuine Toyota FA20 direct-injector seal tool set. Confirm service procedure and VIN before disassembly.Supersession
Service-kit and tooling page, not a supersession. Each injector needs the specified seal stack and combustion seals must be installed and sized with the correct tool/process.
Fitment
First-generation FA20 FRS/BRZ/86 direct injectors. This is not a casual O-ring swap: depressurization, cleanliness, injector identification, seal installation/sizing and leak checking matter. Do not attribute every high-RPM misfire to injector seals without diagnosis.
Aftermarket options
Checked Fensport genuine four-injector seal kit and genuine Toyota installer tool set. Checked Injector Shop rebuild kit includes upper O-rings, retainers, spacers, filters and Teflon combustion seals, and explicitly says tooling is required for installation and sizing.
Before you buy
FA20 direct-injector service requires correct seal installation/sizing tooling and a clean service procedure. The checked genuine tool was not in stock. Diagnose codes, compression, ignition and fueling before assuming a seal failure. Seller-depth exception: Three exact paths are acceptable for this specialized bundled service. Do not pad with individual seals that do not match the verified kit or tool set.
