looking to source 660 ijectors for 04 sti found some but they vary in colour, some are red and some are yellow both claim to be direct drop in versions. i may be wrong but i thought they were colour matched to the cc size or am i wrong.

 

I bought these SARD 650cc yellow injectors from this site. Cannot fault the service. If do decide to buy from them, use the gift wrapping service to avoid import duty. Worked for me.
