what injectors? think i may have wrong ones?
 

Hi everyone... I have a 2003 wrx.

What injectors do I have standard?

Do I need side feed or top feed?

I have bought some denso 550s which are top feed will they fit?

Thanks

yes you need top feed, the ones you have bought will be ok.

2003 will be top feed :)

The pink STI injectors (which I guess you have) flow 565cc when tested but the factory rate those at 534-520cc (depending on what you read).

Your WRX blue injectors flow 440cc and factory rate them at circa 410cc.

Both are top feed :D
