NO if:

• They came from the Z6, or anything OBD-1 or OBD2A/B AND from a Honda

YES if:

• You're not sure where they came from, or what OBD they are, OR if they came from an OBD-0 (non OBD) Honda engine.

Some injector tips:

• Always go with the car you got them from... if it has one, use one.
• If you're unsure, use one anyway, it won't hurt.
• NEVER mix and match. Don't use 2 that need it and 2 that don't.
• DSM injectors, if you ever use them, some use it, some don't. Never just assume you don't need it. Always assume you will.
• Replace your lower injector seals, even if you don't think they need to be... you can't easily test for a vacuum leak under load.
